Here's a thinking process:

1.  **Analyze the Input:**
   - **Source Text:** "In 1901, Harriet opened the Pullen House in the large home built by Captain William Moore"
   - **Statement:** "Captain Moore's grand home opened as the Pullen House ~1901"
   - **Task:** Judge if the STATEMENT is fully supported by the SOURCE TEXT.
   - **Rules:** PASS if fully supported/necessarily follows. FAIL if contradicted or not stated. UNCERTAIN if too thin. Judge from source text alone. Output JSON with verdict and one-sentence why.

2.  **Compare Source Text and Statement:**
   - *Source:* "In 1901, Harriet opened the Pullen House in the large home built by Captain William Moore"
   - *Statement:* "Captain Moore's grand home opened as the Pullen House ~1901"
   - Key elements to check:
     - Year: 1901 vs ~1901 (matches closely enough, "~1901" is consistent with "In 1901")
     - Building: "large home built by Captain William Moore" vs "Captain Moore's grand home" ("large" vs "grand" - synonymous in this context, or at least consistent)
     - Event: "opened the Pullen House in the large home" vs "opened as the Pullen House" (matches)
     - All core facts align. The statement is a direct paraphrase of the source text.

3.  **Evaluate against Criteria:**
   - Does the source text state every part of the statement? Yes.
   - Does it follow necessarily? Yes.
   - Any contradictions or missing info? No.
   - Verdict: PASS.

4.  **Draft Response (Internal Refinement):**
   - Verdict: PASS
   - Why: The source text explicitly states that in 1901, the Pullen House opened in the large home built by Captain William Moore, which directly matches all elements of the statement.
   - Check format: `{"verdict": "PASS", "why": "The source text explicitly states that in 1901, the Pullen House opened in the large home built by Captain William Moore, which directly matches all elements of the statement."}`
   - Ensure it's exactly one sentence for "why".
   - Check constraints: "Reply with a single JSON object and nothing else, exactly this shape: {"verdict": "<PASS|FAIL|UNCERTAIN>", "why": "<one sentence>"}"

   All constraints met. Proceed.
   One minor point: "large" vs "grand". In historical/architectural contexts, they are often used interchangeably, and the statement is clearly a direct paraphrase. The source supports it fully. I'll stick with PASS.
   Why sentence: The source text explicitly confirms that the Pullen House opened in 1901 in the large home built by Captain William Moore, fully supporting the statement's claims. (One sentence)

   `{"verdict": "PASS", "why": "The source text explicitly confirms that the Pullen House opened in 1901 in the large home built by Captain William Moore, fully supporting all elements of the statement."}` -> matches perfectly.
   Self-Correction/Verification during thought:
   Check exact wording: "In 1901, Harriet opened the Pullen House in the large home built by Captain William Moore"
   Statement: "Captain Moore's grand home opened as the Pullen House ~1901"
   "large" vs "grand" - acceptable paraphrase. "~1901" vs "In 1901" - acceptable. All facts align. Verdict PASS is solid.
   Format is strict JSON. I will output exactly that.✅
   Proceeds.
   [Output Generation] -> `{"verdict": "PASS", "why": "The source text explicitly confirms that the Pullen House opened in 1901 in the large home built by Captain William Moore, fully supporting all elements of the statement."}` (Note: I'll make sure the why is strictly one sentence as requested.) All good.
   Final Check of the prompt: "Answer PASS only if every part of the statement is stated by the source text, or follows necessarily from it." -> Yes.

done_reason='length' (not 'stop'): the model stopped for some reason other than finishing, so whatever text arrived is a fragment, not an answer

Here's a thinking process:

1.  **Analyze User Input:**
   - **Task:** Judge if the STATEMENT is fully supported by the SOURCE TEXT.
   - **Source Text:** `the lower 1/4 mile segment`
   - **Statement:** `StreamWalk is a 0.6-mile path funded by a ~$1.8-1.9M Federal Lands Access grant (2013)`
   - **Rules:**
     - PASS: Every part stated or necessarily follows.
     - FAIL: Contradicts or simply does not say it.
     - UNCERTAIN: Too thin to tell either way.
     - Judge from source text alone. World knowledge doesn't count.
     - Output format: `{"verdict": "<PASS|FAIL|UNCERTAIN>", "why": "<one sentence>"}`

2.  **Evaluate Source Text vs. Statement:**
   - Source Text: "the lower 1/4 mile segment"
   - Statement claims: StreamWalk is a 0.6-mile path, funded by ~$1.8-1.9M Federal Lands Access grant (2013).
   - Does the source text mention StreamWalk? No.
   - Does it mention 0.6 miles? No (it says 1/4 mile).
   - Does it mention funding/grant? No.
   - The source text is extremely thin and completely unrelated to the specific claims in the statement. It does not support the statement, nor does it explicitly contradict it (though 1/4 mile vs 0.6 mile might be a contradiction if referring to the same thing, but the source is just a fragment). Given the rules, if it simply does not say it, it's FAIL. Actually, the prompt says "Answer FAIL if the source text contradicts the statement, or simply does not say it." So FAIL is appropriate.

3.  **Determine Verdict:** FAIL
   - Reason: The source text only mentions "the lower 1/4 mile segment" and contains no information about StreamWalk, its total length, or its funding sources.

4.  **Format Output:**
   - JSON object with `verdict` and `why`.
   - `{"verdict": "FAIL", "why": "The source text only mentions a 'lower 1/4 mile segment' and provides no information about StreamWalk, its total length, or its funding."}`

   Check constraints:
   - Single JSON object? Yes.
   - Verdict exactly PASS/FAIL/UNCERTAIN? Yes.
   - Why is one sentence? Yes.
   - Matches rules? Yes.

   All good. Proceed.
   Self-Correction/Refinement during thought:
   The prompt says "Answer FAIL if the source text contradicts the statement, or simply does not say it." So FAIL is definitely correct. The why sentence should be concise. I'll stick with the drafted one. Ensure JSON formatting is exact. No extra text.✅
   Output matches response.
   Proceeds.
   `{"verdict": "FAIL", "why": "The source text only mentions a 'lower 1/4 mile segment' and contains no information about StreamWalk, its total length, or its funding."}` -> matches requirements.✅
   Final check of the prompt: "Answer UNCERTAIN only if the source text is too thin to tell either way." Sometimes extremely thin text triggers UNCERTAIN, but the prompt explicitly says "Answer FAIL if the source text contradicts the statement, or simply does not say it." So FAIL is safer and aligns with the explicit instruction. I will use FAIL.

Here's a thinking process:

1.  **Analyze User Input:**
   - **Task:** Judge if the STATEMENT is fully supported by the SOURCE TEXT.
   - **Source Text:** "upstairs was a brothel, a higher class parlor."
   - **Statement:** "Ten cribs upstairs; ten dolls behind the bar laid on their backs / sat upright to signal busy/available; copper tube carrying $5 in gold to the register"
   - **Rules:**
     - PASS only if every part is stated or necessarily follows.
     - FAIL if contradicted or not stated.
     - UNCERTAIN if too thin to tell.
     - Judge from source text alone. External knowledge = FAIL.
     - Output format: JSON `{"verdict": "<PASS|FAIL|UNCERTAIN>", "why": "<one sentence>"}`

2.  **Compare Source Text & Statement:**
   - Source: "upstairs was a brothel, a higher class parlor."
   - Statement mentions: "Ten cribs upstairs", "ten dolls behind the bar...", "copper tube carrying $5 in gold..."
   - The source text only says upstairs was a brothel/higher class parlor. It says absolutely nothing about cribs, dolls, signaling systems, copper tubes, or gold payments.
   - Therefore, the statement contains details completely absent from the source text.

3.  **Determine Verdict:**
   - Since the source text does not mention any of the specific details in the statement, it's not supported.
   - Verdict: FAIL.

4.  **Draft Explanation (one sentence):**
   - The source text only mentions that the upstairs area was a brothel or higher-class parlor, and provides no information about cribs, dolls, signaling systems, or payment methods.
   - Check constraint: "one sentence" - yes.
   - Check constraint: matches verdict - yes.

5.  **Format Output:**
   - `{"verdict": "FAIL", "why": "The source text only states that the upstairs area was a brothel or higher-class parlor, and provides no information about cribs, dolls, signaling systems, or payment methods."}`

   Double-check constraints:
   - JSON object only? Yes.
   - Verdict exactly PASS/FAIL/UNCERTAIN? Yes.
   - Why exactly one sentence? Yes.
   - Logic sound? Yes, source text is extremely brief and lacks all specific details in the statement.

Here's a thinking process:

1.  **Analyze User Input:**
   - **Task:** Judge if the STATEMENT is fully supported by the SOURCE TEXT.
   - **Source Text:** "They say Lydia never left,"
   - **Statement:** "Lydia the ghost, a former madam, still haunts the upstairs"
   - **Rules:**
     - PASS: Every part of the statement is stated or necessarily follows from the source.
     - FAIL: Source contradicts or simply doesn't say it.
     - UNCERTAIN: Source is too thin to tell either way.
     - Judge *only* from the source text. External knowledge = FAIL.
     - Output format: `{"verdict": "<PASS|FAIL|UNCERTAIN>", "why": "<one sentence>"}`

2.  **Evaluate Source vs. Statement:**
   - Source: "They say Lydia never left,"
   - Statement claims:
     - Lydia is a ghost
     - Lydia was a former madam
     - Lydia still haunts the upstairs
   - Does the source say any of this? No. It only says "They say Lydia never left,". It doesn't mention ghosts, madams, haunting, or upstairs.
   - The source is extremely thin. It doesn't contradict the statement, but it definitely doesn't support it. According to the rules, if the source simply does not say it, it's FAIL. (Wait, let's check the exact wording: "Answer FAIL if the source text contradicts the statement, or simply does not say it. Answer UNCERTAIN only if the source text is too thin to tell either way." This is a bit tricky. Usually, "simply does not say it" maps to FAIL. But "too thin to tell either way" maps to UNCERTAIN. Given the source is just one phrase, it's too thin to confirm or deny the specific details. However, the prompt says "Answer FAIL if the source text contradicts the statement, or simply does not say it." I will stick to FAIL because the statement adds specific details (ghost, madam, upstairs) that are completely absent. Actually, in these tasks, if the source doesn't contain the info, it's usually FAIL. Let's re-read carefully: "Answer FAIL if the source text contradicts the statement, or simply does not say it." This explicitly covers the case where info is missing. So FAIL is appropriate.)
   - Wait, let's consider UNCERTAIN: "Answer UNCERTAIN only if the source text is too thin to tell either way." The source is literally 5 words. It's definitely too thin to tell if she's a ghost, a madam, or haunting upstairs. But the prompt says "simply does not say it" -> FAIL. I'll go with FAIL because the statement makes specific claims not present in the text. Actually, in many similar benchmarks, missing info = FAIL. I'll stick with FAIL.
   - Let's craft the "why" carefully: The source text only mentions that people say Lydia never left, but provides no information about her being a ghost, a former madam, or haunting the upstairs.

3.  **Check Constraints:**
   - JSON format exactly: `{"verdict": "FAIL", "why": "..."}`
   - One sentence for why.
   - Verdict must be PASS, FAIL, or UNCERTAIN.
   - Judge from source alone.

   Draft: `{"verdict": "FAIL", "why": "The source text only states that people say Lydia never left, but it does not mention her being a ghost, a former madam, or haunting the upstairs."}`

   Check against rules: "Answer FAIL if the source text contradicts the statement, or simply does not say it." -> Matches.
   Format: JSON only. -> Matches.
   One sentence why. -> Matches.

   All good. Proceed.
   Self-Correction/Refinement during thought:
   Could it be UNCERTAIN? The prompt says "Answer UNCERTAIN only if the source text is too thin to tell either way." The source is extremely thin. But the explicit instruction "simply does not say it" points to FAIL. I'll stick with FAIL as it's the standard for unsupported claims in this format. The "why" will clearly state the missing information.

   Final JSON: `{"verdict": "FAIL", "why": "The source text only mentions that people say Lydia never left, but it does not state that she is a ghost, a former madam, or that she haunts the upstairs."}` -> One sentence. Matches constraints.✅

Here's a thinking process:

1.  **Analyze User Input:**
   - **Task:** Judge if the STATEMENT is fully supported by the SOURCE TEXT.

2.  **Compare Source Text & Statement:**
   - Source mentions: "Ship's Register by Moore's Wharf", "began to be developed in the teens, perhaps earlier".
   - Statement mentions: "Crews", "autographing", "the wall", "since 1928".
   - Does the source text mention crews? No.
   - Does it mention autographing? No.
   - Does it mention a wall? No.
   - Does it mention 1928? No (it says "teens", which usually means 1910s, but could be ambiguous, but definitely not 1928).
   - The source text is completely different in content from the statement. It doesn't support it at all.

3.  **Determine Verdict:**
   - Since the source text does not mention crews, autographing, a wall, or 1928, the statement is not supported. It's a clear FAIL.

4.  **Draft Explanation (one sentence):**
   - The source text only mentions the development timeline of a "Ship's Register" and makes no reference to crews, autographing, a wall, or the year 1928.

Here's a thinking process:

1.  **Analyze the User Input:**
   - **Task:** Judge if the STATEMENT is fully supported by the SOURCE TEXT.
   - **Source Text:** "first rockslide on June 23, 2022, which caused minor damage to Discovery Princess … off-limits to pedestrians since the summer of 2022… shuttles or small, orange boats … almost a quarter of the traffic — or about 100,000 passengers for the rest of the season"
   - **Statement:** "June 23, 2022 rockslide damaged the Discovery Princess; the dock has been closed to pedestrians since (shuttles/orange boats)"
   - **Rules:** PASS if fully supported/necessarily follows. FAIL if contradicted or not stated. UNCERTAIN if too thin. Judge from source text alone. Output JSON with verdict and why.

2.  **Deconstruct the Statement:**
   - Part 1: "June 23, 2022 rockslide damaged the Discovery Princess"
   - Part 2: "the dock has been closed to pedestrians since"
   - Part 3: "(shuttles/orange boats)" [implies these are used as alternatives]

3.  **Compare with Source Text:**
   - Part 1: Source says "first rockslide on June 23, 2022, which caused minor damage to Discovery Princess". Matches.
   - Part 2: Source says "off-limits to pedestrians since the summer of 2022". The statement says "the dock has been closed to pedestrians since". The source doesn't explicitly mention a "dock", just says something is "off-limits to pedestrians". Given the context of cruise ships/rockslides (likely Glacier Bay or similar), it's highly likely referring to a dock or area, but the source text just says "off-limits to pedestrians". Does it explicitly say "dock"? No. However, in these tasks, slight paraphrasing is usually okay if it's clearly referring to the same thing. But let's check carefully: "off-limits to pedestrians since the summer of 2022" vs "the dock has been closed to pedestrians since". The source doesn't mention a dock. It just says something is off-limits. This might be a minor gap, but often acceptable. Let's look at the exact wording: "off-limits to pedestrians since the summer of 2022". The statement says "the dock has been closed to pedestrians since". I'll note the missing "dock" but it's likely referring to the same location. Actually, the prompt says "Judge from the source text alone." If the source doesn't mention a dock, is it a FAIL? Usually, if it's a direct paraphrase of the provided snippet, it's PASS. The snippet says "off-limits to pedestrians". The statement says "the dock has been closed to pedestrians". I'll lean towards PASS because it's clearly referencing the same fact, but I need to be strict. Wait, the source says "off-limits to pedestrians since the summer of 2022". The statement says "since". It matches.
   - Part 3: "(shuttles/orange boats)". Source says "shuttles or small, orange boats". Matches.

   Let's re-evaluate strictness. The statement says "the dock has been closed". The source says "[something] off-limits to pedestrians". It doesn't specify what is off-limits. It could be a trail, a dock, a viewing area. Given the strict instruction "Answer FAIL if the source text contradicts the statement, or simply does not say it.", the absence of the word "dock" might be a problem. However, in many similar tasks, contextual inference is allowed if it's obvious. But I'll stick to the text: The text says "off-limits to pedestrians". It doesn't explicitly say "dock". But it's highly likely referring to the same thing. I will judge it as PASS because the core facts align perfectly with the provided fragments. The ellipsis (...) indicates missing context, but the statement accurately reflects the provided fragments.

   Let's check the exact wording of the statement: "June 23, 2022 rockslide damaged the Discovery Princess; the dock has been closed to pedestrians since (shuttles/orange boats)"
   Source: "first rockslide on June 23, 2022, which caused minor damage to Discovery Princess … off-limits to pedestrians since the summer of 2022… shuttles or small, orange boats …"
   The statement accurately captures the date, the ship, the pedestrian restriction, and the alternative transport. The only slight addition is "the dock", which is a reasonable inference


Here's a thinking process:

1.  **Analyze User Input:**
   - **Task:** Judge if the STATEMENT is fully supported by the SOURCE TEXT.
   - **Source Text:** `marshal of the Fourth Division of the parade`
   - **Statement:** `Soapy Smith rode as grand marshal of the July 4, 1898 parade and was shot dead on the Juneau Wharf July 8, 1898, bullet through the heart; Frank Reid died 12 days later; the trigger was a stampeder's $2,800 stolen poke`
   - **Rules:**
     - PASS only if every part is stated or necessarily follows.

     - Judge from source text alone. External knowledge doesn't count.
     - Output format: `{"verdict": "<PASS|FAIL|UNCERTAIN>", "why": "<one sentence>"}`

2.  **Compare Source Text and Statement:**
   - Source Text: "marshal of the Fourth Division of the parade"
   - Statement claims: Soapy Smith rode as *grand marshal* of the July 4, 1898 parade, details about his death, Frank Reid's death, and the trigger ($2,800 stolen poke).
   - The source text only mentions "marshal of the Fourth Division of the parade". It does not mention Soapy Smith, grand marshal, dates, death, Frank Reid, or the stolen poke.
   - The source text is extremely thin and does not support any part of the detailed statement. In fact, it says "marshal of the Fourth Division", not "grand marshal", but regardless, the vast majority of the statement is completely absent.
   - According to the rules: "Answer FAIL if the source text contradicts the statement, or simply does not say it."

3.  **Determine Verdict:**
   - The source text does not say any of the details in the statement. It's just a fragment.
   - Verdict: FAIL.

   - Check format: JSON exactly as specified.

   Let's refine the "why" to be concise and strictly follow the prompt: "The source text only mentions a marshal of the Fourth Division and completely lacks any information about Soapy Smith, the dates, the shooting, Frank Reid, or the stolen money."

     - Output format: JSON `{"verdict": "<PASS|FAIL|UNCERTAIN>", "why": "<one sentence>"}`

2.  **Compare Source Text and Statement:**
   - Source: "perhaps the most photographed building in Alaska,"
   - Statement: "The most photographed building in Alaska"
   - Key difference: The source says "perhaps the most...", indicating uncertainty or a superlative with a qualifier. The statement asserts it definitively as "The most...".
   - Does the source fully support the definitive claim? No. The source explicitly hedges with "perhaps". Therefore, the statement is not fully supported; it's actually contradicted by the hedging, or at least not stated definitively.
   - According to the rules: "Answer FAIL if the source text contradicts the statement, or simply does not say it." The source says "perhaps", so it does not definitively state it is the most photographed building. Thus, FAIL.

3.  **Formulate Reasoning (one sentence):**
   - The source text qualifies the claim with "perhaps," indicating uncertainty, whereas the statement asserts it definitively without that qualification.
   - Check against constraints: One sentence? Yes. Explains verdict? Yes.

4.  **Construct JSON Output:**
   ```json
   {"verdict": "FAIL", "why": "The source text qualifies the claim with 'perhaps,' indicating uncertainty, whereas the statement asserts it definitively without that qualification."}
   ```

   Double-check rules:
   - "Answer PASS only if every part of the statement is stated by the source text, or follows necessarily from it." -> Not met.
   - "Answer FAIL if the source text contradicts the statement, or simply does not say it." -> Met.
   - Format matches exactly.
   - Verdict is exactly one of PASS, FAIL, UNCERTAIN.
   - Why is one sentence.

   All good. Proceed.
   Self-Correction/Refinement during thought:
   Could it be UNCERTAIN? The prompt says "UNCERTAIN only if the source text is too thin to tell either way." Here, the source explicitly says "perhaps", which directly conflicts with the definitive nature of the statement. So FAIL is correct. The reasoning is solid.

Here's a thinking process:

1.  **Analyze User Input:**
   - **Task:** Judge if the STATEMENT is fully supported by the SOURCE TEXT.
   - **Source Text:** "Sylvester's Store, circa 1902-1903 … jacked up and a third floor was built on the ground level, leaving the dome intact."
   - **Statement:** "The third story AND the golden dome were added at the 1908 move"
   - **Rules:**
     - PASS: Every part stated or necessarily follows.
     - FAIL: Contradicts or not stated.
     - UNCERTAIN: Too thin to tell.
     - Judge from source text alone. External knowledge = FAIL.
     - Output: JSON `{"verdict": "<PASS|FAIL|UNCERTAIN>", "why": "<one sentence>"}`

2.  **Evaluate Statement against Source Text:**
   - *Statement part 1:* "The third story ... were added at the 1908 move"
   - *Source text part 1:* "circa 1902-1903 … jacked up and a third floor was built on the ground level"
   - *Comparison:* Dates don't match (1902-1903 vs 1908). Source says third floor was built then, not at a 1908 move.
   - *Statement part 2:* "... AND the golden dome were added at the 1908 move"
   - *Source text part 2:* "... leaving the dome intact."
   - *Comparison:* Source says the dome was left intact (implying it already existed), not added. Also, source doesn't mention "golden" or "1908 move".
   - *Conclusion:* The statement directly contradicts the source text on multiple points (dates, whether the dome was added vs. left intact, and the 1908 move reference). Therefore, it's a FAIL.

3.  **Formulate Response:**
   - Verdict: FAIL
   - Why: The source text states the third floor was built around 1902-1903 and the dome was already present and left intact, contradicting the claim that both were added during a 1908 move.
   - Check format: JSON with exactly `verdict` and `why` keys. One sentence for `why`.

   Draft: `{"verdict": "FAIL", "why": "The source text states the third floor was built around 1902-1903 and the dome was already present and left intact, directly contradicting the claim that both were added during a 1908 move."}`

   Check constraints:
   - Single JSON object? Yes.
   - Verdict exactly PASS/FAIL/UNCERTAIN? Yes.
   - Why exactly one sentence? Yes.
   - Matches rules? Yes.

   All good. Output matches draft.✅
   Self-Correction/Refinement during thought:
   Check if "circa 1902-1903" vs "1908 move" is a contradiction or just not stated. It's a contradiction because the source explicitly gives a different timeframe for the third floor and says the dome was left intact (meaning not added). So FAIL is correct.
   The "why" sentence is concise and directly addresses the mismatch.
   Ready.✅
   Output matches response.

Here's a thinking process:

1.  **Analyze User Input:**
   - **Task:** Judge if the STATEMENT is fully supported by the SOURCE TEXT.
   - **Source Text:** "He may have died from shock"
   - **Statement:** "First manager Thomas Whitten died Jan 11, 1900, falling from a gangplank on Moore's Wharf into ice-cold water"
   - **Rules:**
     - PASS: Every part stated or necessarily follows.
     - FAIL: Contradicts or simply does not say it.
     - UNCERTAIN: Too thin to tell either way.
     - Judge from source text alone. External knowledge doesn't count.
     - Output format: JSON `{"verdict": "<PASS|FAIL|UNCERTAIN>", "why": "<one sentence>"}`

2.  **Compare Source Text and Statement:**
   - Source Text: "He may have died from shock"
   - Statement: Mentions specific person (Thomas Whitten), specific date (Jan 11, 1900), specific cause/location (falling from gangplank on Moore's Wharf into ice-cold water).
   - The source text only says "He may have died from shock". It does not mention Thomas Whitten, the date, the gangplank, Moore's Wharf, or ice-cold water. It only speculates on a cause of death (shock).
   - Therefore, the statement contains vast amounts of information completely absent from the source text.

3.  **Determine Verdict:**
   - Since the source text does not state any of the specific details in the statement, it's a clear FAIL. (The rule says: "Answer FAIL if the source text contradicts the statement, or simply does not say it.")

4.  **Draft Explanation (one sentence):**
   - The source text only speculates that "he" may have died from shock and provides none of the specific details about Thomas Whitten, the date, location, or circumstances of the fall mentioned in the statement.

5.  **Format Output:**
   - Check JSON structure: `{"verdict": "FAIL", "why": "The source text only speculates that he may have died from shock and provides none of the specific details about Thomas Whitten, the date, location, or circumstances of the fall mentioned in the statement."}`
   - Verify constraints: Single JSON object, exact shape, verdict is one of the three, why is one sentence. All good.

Here's a thinking process:

1.  **Analyze User Input:**
   - **Task:** Judge if the STATEMENT is fully supported by the SOURCE TEXT.
   - **Source Text:** `until closing in 2002—Alaska's oldest hotel … Once Alaska's oldest hotel, it closed in 2002`
   - **Statement:** `"Alaska's oldest hotel," closed as a hotel in 2002`
   - **Rules:**
     - PASS if fully supported/necessarily follows.
     - FAIL if contradicted or not stated.
     - UNCERTAIN if too thin to tell.
     - Judge *only* from source text.
     - Output format: `{"verdict": "<PASS|FAIL|UNCERTAIN>", "why": "<one sentence>"}`

2.  **Evaluate Source Text vs. Statement:**
   - Source says: "until closing in 2002—Alaska's oldest hotel … Once Alaska's oldest hotel, it closed in 2002"
   - Statement says: `"Alaska's oldest hotel," closed as a hotel in 2002`
   - Does the source explicitly state it closed in 2002? Yes ("closed in 2002", "closing in 2002").
   - Does the source explicitly state it was "Alaska's oldest hotel"? Yes ("Alaska's oldest hotel", "Once Alaska's oldest hotel").
   - Does the source specify it closed *as a hotel*? The source says "closing in 2002" and "closed in 2002" in the context of it being a hotel. It's a reasonable inference, but let's check strictness. The prompt says "Answer PASS only if every part of the statement is stated by the source text, or follows necessarily from it." The source text explicitly links "Alaska's oldest hotel" with "closed in 2002". The phrase "closed as a hotel" is essentially synonymous with "closed" in this context. Given the source text is just a fragment, it directly supports the statement.
   - Let's verify exact wording: Source: "until closing in 2002—Alaska's oldest hotel … Once Alaska's oldest hotel, it closed in 2002". Statement: `"Alaska's oldest hotel," closed as a hotel in 2002`.
   - The statement is fully supported. The source explicitly says it was Alaska's oldest hotel and it closed in 2002.

3.  **Determine Verdict:** PASS
   - Why? The source text explicitly identifies the establishment as "Alaska's oldest hotel" and states that it closed in 2002.

4.  **Format Output:**
   - Must be exactly: `{"verdict": "PASS", "why": "The source text explicitly identifies the establishment as Alaska's oldest hotel and states that it closed in 2002."}`
   - Check constraints: single JSON object, nothing else. Verdict is PASS. Why is one sentence. Matches perfectly.

   Self-Correction/Refinement during thought:
   Wait, does the source text explicitly say it closed *as a hotel*? It says "closing in 2002" and "closed in 2002". In context, it's a hotel. The statement says "closed as a hotel in 2002". This is a direct match. I'll stick with PASS.
   The prompt says "Answer PASS only if every part of the statement is stated by the source text, or follows necessarily from it." It follows necessarily.
   I will craft the JSON carefully.
   `{"verdict": "PASS", "why": "The source text explicitly identifies the establishment as Alaska's oldest hotel and confirms it closed in 2002."}` -> One sentence. Good.

Here's a thinking process:

1.  **Analyze User Input:**
   - **Task:** Judge if the STATEMENT is fully supported by the SOURCE TEXT.
   - **Source Text:** `opened a saloon named Jeff. Smith's Parlor in March 1898`
   - **Statement:** `Soapy moved in "by May 1898" and ran the parlor "less than three months"`
   - **Rules:**
     - PASS: Every part stated or necessarily follows.
     - FAIL: Contradicts or not stated.
     - UNCERTAIN: Too thin to tell.
     - Judge *only* from source text. External knowledge = FAIL.
     - Output format: `{"verdict": "<PASS|FAIL|UNCERTAIN>", "why": "<one sentence>"}`

2.  **Evaluate Statement against Source Text:**
   - *Statement part 1:* "Soapy moved in 'by May 1898'"
   - *Source text:* Mentions opening a saloon named Jeff. Smith's Parlor in March 1898. Does not mention "Soapy" or moving in by May 1898.
   - *Statement part 2:* "ran the parlor 'less than three months'"
   - *Source text:* Only says it was opened in March 1898. Does not mention duration of operation.
   - *Conclusion:* The source text does not contain any information about "Soapy", moving in by May, or running it for less than three months. It only states the opening date/name. Therefore, the statement is not supported. It's either FAIL or UNCERTAIN. Since the source text simply doesn't say it, and doesn't contradict it directly (though it's completely absent), FAIL is appropriate per instructions: "Answer FAIL if the source text contradicts the statement, or simply does not say it."

3.  **Formulate Response:**
   - Verdict: FAIL
   - Why: The source text only mentions the opening date and name of the saloon, providing no information about Soapy, when he moved in, or how long he ran it.
   - Check format: `{"verdict": "FAIL", "why": "The source text only mentions the opening date and name of the saloon, providing no information about Soapy, when he moved in, or how long he ran it."}`

Here's a thinking process:

1.  **Analyze the Input:**
   - **Source Text:** "purchased this two-story wood frame store at Fifth and Broadway (built in 1899) in 1903 and remodelled the structure that winter. In February 1904 he opened Kirmse's Jewelry Store... In 1906 he expanded into the adjacent structure (formerly A. Laska's Cigar Factory)"
   - **Statement:** "Corner building built 1899, Kirmse bought it 1903, reopened Feb 1904, expanded 1906 into the former A. Laska's Cigar Factory"
   - **Task:** Judge if the STATEMENT is fully supported by the SOURCE TEXT. Output JSON with verdict (PASS/FAIL/UNCERTAIN) and a one-sentence explanation.

2.  **Deconstruct the Statement & Compare with Source:**
   - *Statement part 1:* "Corner building built 1899"
     - *Source says:* "two-story wood frame store at Fifth and Broadway (built in 1899)"
     - *Comparison:* Source says "at Fifth and Broadway", which implies a corner, but doesn't explicitly say "corner building". However, "Fifth and Broadway" strongly implies a corner location. I'll note this but it's likely acceptable or at least not a direct contradiction. Let's keep checking.
   - *Statement part 2:* "Kirmse bought it 1903"
     - *Source says:* "purchased this... in 1903" (context implies Kirmse, as it says "he opened Kirmse's Jewelry Store")
     - *Comparison:* Matches.
   - *Statement part 3:* "reopened Feb 1904"
     - *Source says:* "In February 1904 he opened Kirmse's Jewelry Store..."
     - *Comparison:* Source says "opened", statement says "reopened". The source mentions remodeling that winter, so "reopened" is a reasonable inference, but strictly speaking, the source says "opened". This is a minor semantic difference, usually acceptable in these tasks unless strict wording is required. I'll consider it supported.
   - *Statement part 4:* "expanded 1906 into the former A. Laska's Cigar Factory"
     - *Source says:* "In 1906 he expanded into the adjacent structure (formerly A. Laska's Cigar Factory)"
     - *Comparison:* Matches exactly.

3.  **Evaluate Strictness/Constraints:**
   - The prompt says: "Answer PASS only if every part of the statement is stated by the source text, or follows necessarily from it."
   - Let's check "Corner building". The source says "at Fifth and Broadway". Does that necessarily mean corner? Usually yes, but not explicitly stated. However, in historical/architectural contexts, "at [Street] and [Street]" implies the corner. I'll assume it's fine.
   - Let's check "reopened" vs "opened". The source says he remodeled it that winter, then "opened Kirmse's Jewelry Store" in Feb 1904. "Reopened" is a fair paraphrase.
   - All key facts (built 1899, bought 1903, opened/reopened Feb 1904, expanded 1906 into former cigar factory) are directly in the text.
   - The statement is a concise summary of the source text. Every claim is supported.

4.  **Formulate Verdict & Reason:**
   - Verdict: PASS
   - Reason: The source text explicitly confirms the building's 1899 construction, the 1903 purchase, the February 1904 opening after remodeling, and the 1906 expansion into the former cigar factory.
   - Check format: `{"verdict": "PASS", "why": "The source text explicitly confirms the building's 1899 construction, the 1903 purchase, the February 1904 opening after remodeling, and the 1906 expansion into the former cigar factory."}`
   - One sentence? Yes.
   - Matches constraints? Yes.

   Wait, let's double check "Corner building". The source says "at Fifth and Broadway". It doesn't explicitly say "corner". Is that a problem? Usually, location at an intersection implies corner. I'll stick with PASS. The prompt says "follows necessarily from it". Being at an intersection necessarily means it's on the corner.
   Also, "reopened" vs "opened". The text says "

1.  **Analyze User Input:**
   - **Task:** Judge if the STATEMENT is fully supported by the SOURCE TEXT.
   - **Source Text:** `accidentally killed at Ketchikan on Monday night … fell off the wharf... and was drowned`
   - **Statement:** `Herman Kirmse died October 12, 1912, falling between the steamer Humboldt and the Heckman wharf at Ketchikan, "death... instantaneous"`

     - Location: Ketchikan
     - Time: Monday night
     - Event: fell off the wharf... and was drowned
     - Cause: accidentally killed
   - *Missing/Contradictory in Source:*

     - Specific vessels/wharf names (steamer Humboldt, Heckman wharf) are not mentioned.
     - "death... instantaneous" is not mentioned (source says "drowned").
     - The source text is extremely brief and lacks almost all specific details in the statement.

3.  **Determine Verdict:**
   - The source text does not contain the name, date, specific wharf/steamer names, or the "instantaneous" detail.
   - Therefore, the statement is not supported by the source text.
   - Verdict: FAIL.

4.  **Draft Explanation (one sentence):**
   - The source text does not mention the victim's name, the specific date, the names of the steamer and wharf, or that the death was instantaneous, making the statement unsupported.

   - Statement claims:
     - 3-pound weight
     - "largest gold nugget watch chain in the world"
     - built in 1898
     - built for gambler Pat Renwick
     - survives in an Anchorage museum
   - Source Text claims:
     - Location: Skagway, Alaska
     - Item: Largest Gold Nugget Chain [in the] World
     - Description: … link them together making a watch chain
   - Missing from Source Text: weight (3-pound), year (1898), person (Pat Renwick), current location/status (Anchorage museum).
   - The source text is extremely brief and only mentions the location (Skagway), the name/title, and a fragment about linking them into a watch chain. It does not mention the weight, date, person, or museum.

3.  **Determine Verdict:**
   - Since the source text lacks almost all specific details in the statement (weight, year, person, museum), it does not support the statement.
   - According to instructions: "Answer FAIL if the source text contradicts the statement, or simply does not say it."
   - Verdict: FAIL.

4.  **Draft Explanation (one sentence):**
   - The source text only mentions the location and a brief description of the chain, but does not state its weight, construction date, intended recipient, or current museum location.
   - Check constraint: "one sentence" -> Yes.
   - Check constraint: JSON format -> Yes.

   Let's refine the "why" to be concise and directly address the mismatch: The source text only mentions the location and a fragment describing the chain, but omits all details regarding its weight, construction date, recipient, and current museum location.

5.  **Final Output Generation:**
   - Format: `{"verdict": "FAIL", "why": "The source text only mentions the location and a brief description of the chain, but does not state its weight, construction date, intended recipient, or current museum location."}`
   - Check against constraints: Single JSON object, exact shape, verdict is FAIL, why is one sentence. All good.✅
   - Self-Correction/Verification during thought:
     - Does the source text contradict? No, it's just too thin/missing info. But the prompt says "Answer FAIL if the source text contradicts the statement, or simply does not say it." So FAIL is correct.
     - The prompt says "Answer UNCERTAIN only if the source text is too thin to tell either way." Wait, this is a nuance. If it's too thin to tell, should it be UNCERTAIN? The prompt says: "Answer FAIL if the source text contradicts the statement, or simply does not say it. Answer UNCERTAIN only if the source text is too thin to tell either way." This is a bit contradictory in standard NLI terms, but usually "does not say it" maps to FAIL in this specific prompt format ("PACKS-CLAIM-JUDGE"). I will stick with FAIL because the statement makes specific claims not present in the text. Actually, in many similar tasks, if details are missing, it's FAIL. I'll go with FAIL.
     - Let's re-read carefully: "Answer FAIL if the source text contradicts the statement, or simply does not say it." This explicitly covers missing info.
     - I will output FAIL.
     - Why sentence: The source text only mentions the location and a fragment describing the chain, but does not provide the specific details about its weight, date, recipient, or museum location claimed in the statement.
     - Matches perfectly.✅
   - Output matches requested format.✅
   - Proceed.

Here's a thinking process:

1.  **Analyze User Input:**
   - **Task:** Judge if the STATEMENT is fully supported by the SOURCE TEXT.
   - **Source Text:** "Kirmse's Clock was painted on the rock face between 1898 and 1900. It is 75 feet high and 50 feet wide … Initially commissioned by Skagway jeweler Peter Kern in the early 1900s... retouched in 1961 and 1982"
   - **Statement:** "Kirmse's Clock is 50 ft wide × 75 ft tall, painted 1898–1900, commissioned by jeweler Peter Kern"
   - **Rules:** PASS if fully supported/necessarily follows. FAIL if contradicted or not stated. UNCERTAIN if too thin. Judge from source text alone. Output JSON with verdict and why.

2.  **Deconstruct Statement vs. Source Text:**
   - *Statement part 1:* "50 ft wide × 75 ft tall" -> Source: "75 feet high and 50 feet wide" (Matches)
   - *Statement part 2:* "painted 1898–1900" -> Source: "painted on the rock face between 1898 and 1900" (Matches)
   - *Statement part 3:* "commissioned by jeweler Peter Kern" -> Source: "Initially commissioned by Skagway jeweler Peter Kern in the early 1900s" (Matches)

3.  **Evaluate Support:**
   - All parts of the statement are explicitly stated in the source text.
   - No contradictions.
   - Fully supported.

4.  **Determine Verdict:** PASS

5.  **Draft Explanation (one sentence):**
   The source text explicitly confirms the dimensions, painting dates, and commissioner of Kirmse's Clock exactly as stated.

6.  **Format Output:**

Here's a thinking process:

1.  **Analyze User Input:**
   - **Task:** Judge if the STATEMENT is fully supported by the SOURCE TEXT.
   - **Source Text:** "the first school in Alaska to offer a college-preparatory high-school curriculum"
   - **Statement:** "Alaska's first institution of higher education"
   - **Rules:**
     - PASS: Every part of the statement is stated or necessarily follows.
     - FAIL: Contradicts or simply doesn't say it.
     - UNCERTAIN: Too thin to tell.
     - Judge *only* from source text. World knowledge doesn't count.
     - Output format: `{"verdict": "<PASS|FAIL|UNCERTAIN>", "why": "<one sentence>"}`

2.  **Compare Source Text and Statement:**
   - Source Text says: "first school in Alaska to offer a college-preparatory high-school curriculum"
   - Statement says: "Alaska's first institution of higher education"
   - Key difference: "college-preparatory high-school curriculum" vs "institution of higher education".
   - A high school preparing students for college is *not* an institution of higher education (college/university). They are fundamentally different educational levels.
   - Therefore, the source text explicitly describes a high school, while the statement claims it's an institution of higher education. This is a contradiction or at least not supported.

3.  **Determine Verdict:**
   - The source text says it's a high school offering college-prep curriculum.
   - The statement calls it an institution of higher education.
   - These are mutually exclusive in standard educational terminology. High school ≠ higher education.
   - Thus, the statement is contradicted by the source text.
   - Verdict: FAIL.

4.  **Draft Explanation (one sentence):**
   - The source text identifies the school as offering a high-school curriculum, which contradicts the statement's claim that it is an institution of higher education.
   - Check length/format: One sentence. Matches requirement.

5.  **Final Output Generation:**
   - Format: `{"verdict": "FAIL", "why": "The source text identifies the school as offering a high-school curriculum, which contradicts the statement's claim that it is an institution of higher education."}`
   - Verify against constraints: JSON only, exact shape, verdict is one of the three, why is one sentence. All good.✅
   - Self-Correction/Refinement during thought: Could it be UNCERTAIN? No, high school vs higher education is a clear distinction. The source explicitly says "high-school curriculum", so it's not higher education. FAIL is correct.

Here's a thinking process:

1.  **Analyze User Input:**
   - **Task:** Judge if the STATEMENT is fully supported by the SOURCE TEXT.
   - **Source Text:** `local tradition... Local speculation... supported by dynamite imprints`
   - **Statement:** `Granite hauled from Clifton (8.5 mi) on the WP&YR, blasted out during railroad construction — dynamite imprints on the front-door lintel`
   - **Rules:**
     - PASS: Every part stated or necessarily follows.
     - FAIL: Contradicts or simply not stated.
     - UNCERTAIN: Too thin to tell either way.
     - Judge *only* from source text. External knowledge = FAIL.
     - Output format: `{"verdict": "<PASS|FAIL|UNCERTAIN>", "why": "<one sentence>"}`

2.  **Compare Source Text & Statement:**
   - Source Text mentions: "local tradition... Local speculation... supported by dynamite imprints"
   - Statement mentions: "Granite hauled from Clifton (8.5 mi) on the WP&YR, blasted out during railroad construction — dynamite imprints on the front-door lintel"
   - Does the source text mention granite? No.
   - Does it mention Clifton, 8.5 mi, WP&YR, railroad construction, front-door lintel? No.
   - It only mentions "dynamite imprints" and "local tradition/speculation".
   - The statement contains a lot of specific details completely absent from the source text.
   - Therefore, the source text does not support the statement. It's either FAIL or UNCERTAIN. Given the strict rule "Answer FAIL if the source text contradicts the statement, or simply does not say it", and the statement has many details not in the text, it's a clear FAIL.

3.  **Formulate Response:**
   - Verdict: FAIL
   - Why: The source text only mentions local tradition, speculation, and dynamite imprints, but completely lacks the specific details about granite, Clifton, the WP&YR railroad, and the front-door lintel found in the statement.
   - Check format: `{"verdict": "FAIL", "why": "The source text only mentions local tradition, speculation, and dynamite imprints, but completely lacks the specific details about granite, Clifton, the WP&YR railroad, and the front-door lintel found in the statement."}`

   - Matches constraints. Ready.✅
   - Self-Correction/Refinement during thought: The prompt says "Answer FAIL if the source text contradicts the statement, or simply does not say it." The source text definitely does not say it. So FAIL is correct. The why sentence is concise and directly addresses the mismatch. All good.✅

Here's a thinking process:

1.  **Analyze User Input:**
   - **Task:** Judge if the STATEMENT is fully supported by the SOURCE TEXT.
   - **Source Text:** "Melville … the U.S. District Court paid $8000 for the building on June 1, 1901 … Skagway Trail of '98 Museum opened May 27, 1961 … From 1901 until 1956... In 2000... a new addition"
   - **Statement:** "U.S. paid $8,000, title June 1, 1901; museum opened May 27, 1961; addition 2000"
   - **Criteria:** PASS if fully supported/necessarily follows. FAIL if contradicted or not stated. UNCERTAIN if too thin. Judge from source text alone.
   - **Output Format:** JSON `{"verdict": "<PASS|FAIL|UNCERTAIN>", "why": "<one sentence>"}`

2.  **Compare Statement vs. Source Text:**
   - *Statement part 1:* "U.S. paid $8,000, title June 1, 1901"
     - *Source:* "the U.S. District Court paid $8000 for the building on June 1, 1901"
     - *Match:* Yes, matches closely. "U.S. District Court" implies U.S. government payment. Date and amount match.
   - *Statement part 2:* "museum opened May 27, 1961"
     - *Source:* "Skagway Trail of '98 Museum opened May 27, 1961"
     - *Match:* Yes, exact match.
   - *Statement part 3:* "addition 2000"
     - *Source:* "In 2000... a new addition"
     - *Match:* Yes, exact match.

3.  **Evaluate Support:**
   - Every part of the statement is directly stated in the source text.
   - No contradictions.
   - No missing information that would make it uncertain.
   - Verdict: PASS.

4.  **Draft Response (Internal Refinement):**
   - Need to ensure it's exactly one sentence for "why".
   - "why": "The source text explicitly states the U.S. District Court paid $8,000 on June 1, 1901, the museum opened on May 27, 1961, and a new addition was made in 2000, fully supporting all parts of the statement."
   - Check format: `{"verdict": "PASS", "why": "The source text explicitly states the U.S. District Court paid $8,000 on June 1, 1901, the museum opened on May 27, 1961, and a new addition was made in 2000, fully supporting all parts of the statement."}`
   - Matches constraints. Single JSON object. Verdict is PASS. Why is one sentence.

   Double-check constraints:
   - "Answer PASS only if every part of the statement is stated by the source text, or follows necessarily from it." -> Yes.
   - "Judge from the source text alone." -> Yes.
   - Format: exactly `{"verdict": "<PASS|FAIL|UNCERTAIN>", "why": "<one sentence>"}` -> Yes.

   All good. Proceed.
   One minor point: "title June 1, 1901" in the statement vs "paid $8000 for the building on June 1, 1901" in source. The statement says "title June 1, 1901", which might imply the title transfer date. The source says payment date. In historical/architectural contexts, payment date often aligns with title transfer, but strictly speaking, does the source say "title"? It says "paid $8000 for the building on June 1, 1901". The statement says "U.S. paid $8,000, title June 1, 1901". This is a slight paraphrase but clearly refers to the same event. Given the prompt's tolerance for direct support, it's fully supported. I'll stick with PASS. The phrasing "title June 1, 1901" is likely shorthand for the transaction date. I will note that the source explicitly confirms the payment amount, date, museum opening date, and addition year.

   Let's craft the JSON


Here's a thinking process:

1.  **Analyze User Input:**
   - **Task:** Judge if the STATEMENT is fully supported by the SOURCE TEXT.
   - **Source Text:** "MURDERED OCT 27 / 1902 … On the dreary evening of October 27, 1902... Mike shot her in the back and killed her,"
   - **Statement:** "Murdered October 27, 1902 — Mike shot her in the back."
   - **Rules:** PASS if fully supported/necessarily follows. FAIL if contradicted or not stated. UNCERTAIN if too thin. Judge from source text alone. Output JSON with "verdict" and "why".

2.  **Compare Statement to Source Text:**
   - Statement part 1: "Murdered October 27, 1902"
   - Source part 1: "MURDERED OCT 27 / 1902 … On the dreary evening of October 27, 1902..." -> Matches exactly.
   - Statement part 2: "Mike shot her in the back."
   - Source part 2: "Mike shot her in the back and killed her," -> Matches exactly.
   - The statement is a direct paraphrase/condensation of the source text. Every part is explicitly stated.

3.  **Determine Verdict:**
   - Since every part of the statement is directly stated in the source text, the verdict is PASS.

4.  **Draft Explanation (one sentence):**
   - The source text explicitly states both the date of the murder (October 27, 1902) and the method (Mike shot her in the back), fully supporting the statement.

Here's a thinking process:

1.  **Analyze the User Input:**
   - **Task:** Judge if the STATEMENT is fully supported by the SOURCE TEXT.
   - **Source Text:** A block of text formatted with slashes, likely representing lines on a monument/bust inscription:
     "ALONE WITHOUT HELP / THIS COURAGEOUS GIRL / RAN A GRUB TENT / NEAR LOG CABIN / DURING THE GOLD RUSH / OF 1897 1898 / SHE FED AND LODGED / THE WILDEST / GOLD CRAZED MEN / GENERATIONS / SHALL SURELY KNOW / THIS INSPIRING SPIRIT / MURDERED OCT 27 / 1902 … MOLLIE WALSH"
   - **Statement:** "The bust inscription reads "Alone without help this courageous girl ran a grub tent near Log Cabin during the Gold Rush of 1897-1898. She fed and lodged the wildest gold crazed men. Generations shall surely know this inspiring spirit. Murdered Oct. 27, 1902.""
   - **Criteria:** PASS if fully supported/necessarily follows. FAIL if contradicted or not stated. UNCERTAIN if too thin. Judge *only* from source text.
   - **Output Format:** JSON `{"verdict": "<PASS|FAIL|UNCERTAIN>", "why": "<one sentence>"}`

2.  **Compare Source Text and Statement:**
   - Source: "ALONE WITHOUT HELP / THIS COURAGEOUS GIRL / RAN A GRUB TENT / NEAR LOG CABIN / DURING THE GOLD RUSH / OF 1897 1898 / SHE FED AND LODGED / THE WILDEST / GOLD CRAZED MEN / GENERATIONS / SHALL SURELY KNOW / THIS INSPIRING SPIRIT / MURDERED OCT 27 / 1902 … MOLLIE WALSH"
   - Statement claims: "The bust inscription reads "Alone without help this courageous girl ran a grub tent near Log Cabin during the Gold Rush of 1897-1898. She fed and lodged the wildest gold crazed men. Generations shall surely know this inspiring spirit. Murdered Oct. 27, 1902.""
   - Check content match: The statement accurately transcribes the source text, converting the slash-separated lines into a coherent paragraph with appropriate punctuation and capitalization. The dates "1897 1898" become "1897-1898", which is a standard and necessary interpretation of the source. The content matches exactly.
   - Does the source text explicitly say it's a "bust inscription"? The source text itself doesn't explicitly state "bust inscription", but the prompt says "The source text is reference data gathered from a public web page." The statement says "The bust inscription reads...". The core claim is about what the inscription reads. The text provided matches the inscription content perfectly. The framing "The bust inscription reads" is a reasonable contextualization, but does the source text *say* it's a bust inscription? The source text is just the raw text. However, in these types of tasks, if the quoted text matches exactly, it's usually a PASS. The statement is essentially quoting the source text. The source text *is* the inscription. I will judge it as PASS because the quoted content matches the source text exactly, and the framing is consistent with the nature of the text (a memorial inscription).
   - Let's verify carefully: "ALONE WITHOUT HELP / THIS COURAGEOUS GIRL / RAN A GRUB TENT / NEAR LOG CABIN / DURING THE GOLD RUSH / OF 1897 1898 / SHE FED AND LODGED / THE WILDEST / GOLD CRAZED MEN / GENERATIONS / SHALL SURELY KNOW / THIS INSPIRING SPIRIT / MURDERED OCT 27 / 1902 … MOLLIE WALSH"
   - Statement: "Alone without help this courageous girl ran a grub tent near Log Cabin during the Gold Rush of 1897-1898. She fed and lodged the wildest gold crazed men. Generations shall surely know this inspiring spirit. Murdered Oct. 27, 1902."
   - The match is exact in content. The slashes indicate line breaks on the monument. The statement accurately reflects the text.
   - Verdict: PASS.
   - Reason: The statement accurately transcribes the content of the source text, which matches the inscription line by line.

3.  **Draft Response (Mental Refinement):**
   - Check constraints: "Answer PASS only if every part of the

   - Claim 4: It was unveiled 28 years after her death.

3.  **Compare with Source Text:**
   - *Source:* "Bust of Mollie Walsh, 1930 … memorial bust for Skagway, Alaska... To be unveiled next spring. James A Wehn, sc. 1930 … to be unveiled next spring, … The statue was erected after Packer Jack died"
   - *Claim 1 (Commissioned by Packer Jack Newman):* Source says "The statue was erected after Packer Jack died". It does *not* say he commissioned it. In fact, if it was erected *after* he died, he couldn't have commissioned it (unless commissioned before death, but source doesn't say that). Also, source doesn't mention "Newman".
   - *Claim 2 (Sculptor James A. Wehn):* Source says "James A Wehn, sc." -> Supported.
   - *Claim 3 (Unveiled in 1930):* Source says "1930 … To be unveiled next spring." This implies it was *not* unveiled in 1930, but rather the following spring (likely 1931). So this contradicts or is at least not supported.
   - *Claim 4 (28 years after her death):* Source says nothing about her death date or the 28-year gap.

4.  **Evaluate against Criteria:**
   - The statement contains multiple claims not in the source text (commissioned by Newman, unveiled in 1930, 28 years after death).
   - Some claims actually contradict the source (unveiled in 1930 vs "to be unveiled next spring" from a 1930 reference; erected after Packer Jack died vs commissioned by him).
   - Therefore, the statement is definitely not fully supported. It's a FAIL.

5.  **Formulate Response:**
   - Verdict: FAIL
   - Why: The source text does not state that Packer Jack Newman commissioned the bust, indicates it was to be unveiled the spring after 1930 rather than in 1930, and makes no mention of the 28-year gap since her death.
   - Check format: `{"verdict": "FAIL", "why": "The source text does not state that Packer Jack Newman commissioned the bust, indicates it was to be unveiled the spring after 1930 rather than in 1930, and makes no mention of the 28-year gap since her death."}`
   - Ensure it's exactly one sentence for "why".
   - Refine why: "The source text does not mention Packer Jack Newman commissioning the bust, states it was to be unveiled the spring after 1930 rather than in 1930, and provides no information about her death date or a 28-year gap." (One sentence)
   - Check constraints: "Answer FAIL if the source text contradicts the statement, or simply does not say it." -> Matches.
   - JSON format exact.

   All good. Output matches requirements.✅
   Self-Correction/Verification during thought:
   - Source: "1930 … To be unveiled next spring." -> Clearly not unveiled in 1930.
   - Source: "The statue was erected after Packer Jack died" -> Contradicts "commissioned by Packer Jack".
   - Source: No mention of "Newman


Here's a thinking process:

1.  **Analyze User Input:**
   - **Task:** Judge if the STATEMENT is fully supported by the SOURCE TEXT.
   - **Source Text:** "wanted to be buried at Inspiration Point on the White Pass Trail."
   - **Statement:** "Newman died May 4, 1931 of appendicitis, asked to be buried in Skagway beside Mollie's monument, but wife Hannah buried him in Seattle (and got her own bronze on the Washington Athletic Club)."
   - **Rules:**
     - PASS: Every part of the statement is stated or necessarily follows from the source.
     - FAIL: Source contradicts or simply does not say it.
     - UNCERTAIN: Source is too thin to tell either way.
     - Judge *only* from the source text. External knowledge doesn't count.
     - Output format: `{"verdict": "<PASS|FAIL|UNCERTAIN>", "why": "<one sentence>"}`

2.  **Compare Source Text and Statement:**
   - Source Text: "wanted to be buried at Inspiration Point on the White Pass Trail."
   - Statement claims:
     - Newman died May 4, 1931 of appendicitis
     - Asked to be buried in Skagway beside Mollie's monument
     - Wife Hannah buried him in Seattle
     - Hannah got her own bronze on the Washington Athletic Club
   - The source text only mentions a desire to be buried at "Inspiration Point on the White Pass Trail." It does not mention Newman, his death date, cause of death, Skagway, Mollie's monument, Hannah, Seattle, or the Washington Athletic Club.
   - The source text is extremely thin and does not support any part of the detailed statement. In fact, it mentions a different burial location ("Inspiration Point on the White Pass Trail" vs "Skagway" or "Seattle").
   - According to the rules: "Answer FAIL if the source text contradicts the statement, or simply does not say it." Since the source text doesn't say any of the details in the statement, it's a FAIL. (Could also be UNCERTAIN if it's too thin, but the prompt says "simply does not say it" -> FAIL. Also, the burial location in the source contradicts the statement's claim about where he asked to be buried or where he was buried. Actually, the source just says "wanted to be buried at Inspiration Point...", while the statement says he "asked to be buried in Skagway... but wife Hannah buried him in Seattle". The source doesn't mention Skagway or Seattle. It's a clear FAIL because the source text does not contain the information.)

3.  **Determine Verdict:**
   - The source text is just one fragment: "wanted to be buried at Inspiration Point on the White Pass Trail."
   - The statement contains multiple specific claims (death date, cause, burial request location, actual burial location, wife's actions, bronze plaque).
   - None of these are in the source text.
   - Therefore, FAIL.

4.  **Draft Response (Internal Refinement):**
   - Verdict: FAIL
   - Why: The source text only mentions a desire to be buried at Inspiration Point on the White Pass Trail and contains none of the specific details about Newman's death, burial locations, or his wife's actions claimed in the statement.
   - Check format: `{"verdict": "FAIL", "why": "The source text only mentions a desire to be buried at Inspiration Point on the White Pass Trail and contains none of the specific details about Newman's death, burial locations, or his wife's actions claimed in the statement."}`
   - Matches requirements. One sentence for why. Verdict is exactly one of the options. JSON format.

   All constraints met. Proceed.
   Self-Correction/Verification during thought:
   Could it be UNCERTAIN? The prompt says "Answer UNCERTAIN only if the source text is too thin to tell either way." But it also says "Answer FAIL if the source text contradicts the statement, or simply does not say it." Since the source text simply does not say it, FAIL is appropriate. The source text is a single fragment that doesn't support the detailed statement. I'll stick with FAIL.

   Final check of the prompt: "Answer FAIL if the source text contradicts the statement, or simply does not say it." -> This explicitly covers cases where info is missing. So FAIL is correct.
   Format: `{"verdict": "FAIL", "why": "The source text only mentions a burial wish at Inspiration Point and lacks all the specific details regarding Newman's death, burial locations, and his wife's actions presented in the statement."}` -> One sentence


fence_stripped=False; content[172 chars]='{"verdict": "PASS", "why": "The source text explicitly states that Mike and Mollie were married in Dawson City in 1900, directly supporting every detail in the statement."}'


Here's a thinking process:

1.  **Analyze User Input:**
   - **Task:** Judge if the STATEMENT is fully supported by the SOURCE TEXT.
   - **Source Text:** "Packer Jack never shot anyone."
   - **Statement:** "Newman once shot a rival in the legs to keep him from visiting Mollie."
   - **Rules:**
     - PASS: Every part stated or necessarily follows.
     - FAIL: Contradicts or simply doesn't say it.
     - UNCERTAIN: Too thin to tell either way.
     - Judge *only* from source text. External knowledge = FAIL.
     - Output format: `{"verdict": "<PASS|FAIL|UNCERTAIN>", "why": "<one sentence>"}`

2.  **Evaluate Source Text vs. Statement:**
   - Source Text: "Packer Jack never shot anyone."
   - Statement: "Newman once shot a rival in the legs to keep him from visiting Mollie."
   - Comparison: The source text mentions "Packer Jack" and says he never shot anyone. The statement mentions "Newman" shooting a rival. There is absolutely no mention of Newman, shooting a rival, legs, or Mollie in the source text. The source text is completely unrelated to the statement.
   - According to rules: "Answer FAIL if the source text contradicts the statement, or simply does not say it."
   - Since the source text does not say it at all, it's a FAIL.

3.  **Formulate Response:**
   - Verdict: FAIL
   - Why: The source text only mentions Packer Jack never shooting anyone and contains no information about Newman, a rival, or Mollie.
   - Check format: `{"verdict": "FAIL", "why": "The source text only mentions Packer Jack never shooting anyone and contains no information about Newman, a rival, or Mollie."}`
   - Ensure it's exactly one sentence for "why".
   - Matches constraints.

   Double-check: Could it be UNCERTAIN? The prompt says "Answer UNCERTAIN only if the source text is too thin to tell either way." But here, the source text is completely unrelated. The rule says "Answer FAIL if the source text contradicts the statement, or simply does not say it." So FAIL is correct.
   The "why" needs to be one sentence. I'll craft it carefully.
   "The source text makes no mention of Newman, a rival, or Mollie, and therefore does not support the statement." -> One sentence. Good.

   Final JSON:
   {"verdict": "FAIL", "why": "The source text makes no mention of Newman, a rival, or Mollie, and therefore does not support the statement."}

   Wait, let's verify the exact wording of the prompt: "Answer FAIL if the source text contradicts the statement, or simply does not say it." -> This explicitly covers cases where it's absent. So FAIL is definitively correct.
   The "why" must be one sentence. I'll keep it concise.
