Here's a thinking process:

1.  **Analyze User Input:**
   - **Task:** Judge if the STATEMENT is fully supported by the SOURCE TEXT.
   - **Source Text:** "Moore cabin is the oldest building in Skagway"
   - **Statement:** "The log cabin "remains the oldest structure in Skagway""
   - **Rules:**
     - PASS: Every part stated or necessarily follows.
     - FAIL: Contradicts or not stated.
     - 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: "Moore cabin is the oldest building in Skagway"
   - Statement: "The log cabin "remains the oldest structure in Skagway""
   - Key differences/alignments:
     - "Moore cabin" vs "The log cabin" -> The source doesn't specify it's a "log" cabin. It just says "Moore cabin".
     - "is the oldest building" vs "remains the oldest structure" -> "building" vs "structure" are close, but "remains" implies a temporal continuity not explicitly stated, though "is" could imply current state. The bigger issue is "log cabin" vs "Moore cabin". The source text does not mention it's a log cabin.
     - Does the source text support that it's a *log* cabin? No.
     - Does the source text support that it *remains* the oldest? It says "is", which is present tense, but "remains" adds a nuance of continuity. More importantly, the material ("log") is completely absent.
     - According to strict rules: "Answer FAIL if the source text contradicts the statement, or simply does not say it."
     - The source text does not say it's a log cabin. Therefore, the statement is not fully supported.

3.  **Determine Verdict:**
   - Verdict: FAIL
   - Reason: The source text does not specify that the Moore cabin is made of logs, nor does it explicitly state that it "remains" the oldest structure, making the statement unsupported by the provided text.

4.  **Format Output:**
   - Must be exactly: `{"verdict": "FAIL", "why": "The source text does not mention that the cabin is made of logs or that it 'remains' the oldest structure, so the statement is not fully supported."}`
   - Check constraints: single JSON object, nothing else. Verdict is one of PASS/FAIL/UNCERTAIN. Why is one sentence.

   Let's refine the "why" to be strictly one sentence and directly address the mismatch.
   "The source text identifies the Moore cabin as the oldest building but does not specify that it is a log cabin or use the word 'remains'." -> One sentence. Good.

   Double check: Could "Moore cabin" imply log cabin? Not necessarily. In strict textual entailment, adding "log" is unsupported. So FAIL is correct.
   Format matches requirement.
   Proceed.
   Output matches exactly.✅

   - Source: "Moore cabin is the oldest building in Skagway"
   - Statement: "The log cabin "remains the oldest structure in Skagway""
   - Missing info: "log", "remains", "structure" vs "building".
   - Verdict: FAIL.
   - Why: The source text does not state that the cabin is made of logs or that it "remains" the oldest structure.
   - All constraints met. Output matches.✅

Here's a thinking process:

1.  **Analyze User Input:**
   - **Task:** Judge if the STATEMENT is fully supported by the SOURCE TEXT.
   - **Source Text:** "Ogilvie named the new route... the White Pass … When Oglivie heard of this new route, he named it White Pass, after Thomas White, the Minister of the Interior"
   - **Statement:** "Moore scouted the pass in June 1887 with Skookum Jim and "christened it 'White Pass'" for Thomas White"
   - **Rules:**
     - PASS: Every part stated or necessarily follows.
     - FAIL: Contradicts or simply 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.  **Compare Statement vs. Source Text:**
   - *Statement claims:* Moore scouted the pass in June 1887 with Skookum Jim.
   - *Source text says:* Ogilvie named the new route... the White Pass... after Thomas White.
   - *Discrepancy 1:* The source text says *Ogilvie* named it, not Moore.
   - *Discrepancy 2:* The source text does not mention Moore, Skookum Jim, or June 1887.
   - *Conclusion:* The statement introduces entities and details completely absent from the source text, and directly contradicts the source text regarding who named it (Ogilvie vs. Moore). Therefore, it's not supported.

3.  **Determine Verdict:**
   - Since the source text explicitly attributes the naming to Ogilvie, and the statement attributes it to Moore (and adds unmentioned details), the statement is not supported. It contradicts the source on the naming agent. Verdict: FAIL.

4.  **Draft Explanation (one sentence):**
   - The source text explicitly states that Ogilvie named the pass, not Moore, and makes no mention of Skookum Jim or June 1887.
   - Check constraint: "one sentence" -> Yes.
   - Check constraint: "Judge from the source text alone" -> Yes.
   - Check constraint: Format -> JSON.

   Refined why: The source text attributes the naming of the pass to Ogilvie rather than Moore and does not mention Skookum Jim or June 1887.

5.  **Final Output Generation:**
   - Construct JSON exactly as requested.
   - `{"verdict": "FAIL", "why": "The source text attributes the naming of the pass to Ogilvie rather than Moore and does not mention Skookum Jim or June 1887."}`

Here's a thinking process:

1.  **Analyze User Input:**
   - **Task:** Judge if the STATEMENT is fully supported by the SOURCE TEXT.
   - **Source Text:** "Moore put up a fight but in the end his home was uprooted and moved to another location."
   - **Statement:** "The crowbar story (Moore charged the surveyors swinging a crowbar)"
   - **Criteria:** 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:** JSON `{"verdict": "<PASS|FAIL|UNCERTAIN>", "why": "<one sentence>"}`

2.  **Evaluate Statement against Source Text:**
   - Source text mentions: Moore fought, his home was uprooted and moved.
   - Statement mentions: "The crowbar story", "Moore charged the surveyors swinging a crowbar".
   - Does the source text mention a crowbar? No.
   - Does it mention surveyors? No.
   - Does it mention Moore charging them? No.
   - The source text is completely silent on the specific details in the statement. It only says he "put up a fight" and his home was moved.
   - Therefore, the statement is not supported by the source text. It introduces new, unmentioned details.
   - Verdict: FAIL.

3.  **Formulate Response:**
   - Verdict: FAIL
   - Why: The source text makes no mention of a crowbar, surveyors, or Moore charging them, so the statement cannot be supported by the provided text.
   - Check format: JSON with exactly `verdict` and `why` keys. One sentence for `why`.

   Draft: `{"verdict": "FAIL", "why": "The source text does not mention a crowbar, surveyors, or Moore charging them, so the statement is not supported."}`

   - Output matches exactly.✅
   - Proceed.

Here's a thinking process:

1.  **Analyze the User Input:**
   - **Task:** Judge if the STATEMENT is fully supported by the SOURCE TEXT.
   - **Source Text:** "In 1900, the Moores detached the log cabin and moved it to its present site 50 feet north of the house … The building sits west of the Moore House"
   - **Statement:** "The cabin was moved a short distance within the lot"
   - **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.  **Evaluate the Statement against the Source Text:**
   - *Statement part 1:* "The cabin was moved" -> Source says "moved it to its present site". Supported.
   - *Statement part 2:* "a short distance" -> Source says "50 feet north of the house". 50 feet is generally considered a short distance. Supported/Reasonable inference.
   - *Statement part 3:* "within the lot" -> Source says "moved it to its present site 50 feet north of the house … The building sits west of the Moore House". It does *not* explicitly state that the move was "within the lot". It just says it was moved 50 feet north of the house. While it's highly likely it stayed on the same property, the source text does not explicitly mention a "lot" or confirm the move was within the same lot boundaries. It could have been moved to an adjacent property, or the text just doesn't specify lot boundaries.
   - Let's check the strictness: "Answer FAIL if the source text contradicts the statement, or simply does not say it." The phrase "within the lot" is not in the text. The text only gives relative position to the house (50 feet north, west of Moore House). It doesn't mention lot boundaries. Therefore, "within the lot" is not stated.
   - Could "50 feet north of the house" imply within the lot? Usually yes, but strictly speaking, the source text doesn't say it. The prompt says "Answer FAIL if the source text ... simply does not say it."
   - Let's consider if "within the lot" is a necessary inference. Not necessarily. It could be on a different lot. The text just says where it sits relative to the house.
   - I will lean towards FAIL because "within the lot" is not mentioned or necessarily implied by the text. The text only specifies distance/direction relative to the house.
   - Wait, could it be UNCERTAIN? "Answer UNCERTAIN only if the source text is too thin to tell either way." The text doesn't say whether it's within the lot or not. So it's too thin to confirm "within the lot". But the prompt says FAIL if it simply does not say it. I'll stick with FAIL because the specific claim "within the lot" is absent.
   - Let's re-read carefully: "In 1900, the Moores detached the log cabin and moved it to its present site 50 feet north of the house … The building sits west of the Moore House"
   - Statement: "The cabin was moved a short distance within the lot"
   - The source says it was moved 50 feet. 50 feet is a short distance. But "within the lot" is not stated. I will mark FAIL.
   - Reasoning: The source text specifies the cabin was moved 50 feet north of the house but does not mention lot boundaries or confirm the move occurred within the same lot.

3.  **Draft Response (Mental Refinement):**
   - Verdict: FAIL
   - Why: The source text states the cabin was moved 50 feet north of the house but does not mention lot boundaries or confirm the move occurred within the same lot.
   - Check format: `{"verdict": "FAIL", "why": "The source text states the cabin was moved 50 feet north of the house but does not mention lot boundaries or confirm the move occurred within the same lot."}`
   - Does it meet criteria? Yes. One sentence. JSON format. Verdict is one of the three. Strictly follows source text.

   Let's double check "short distance". 50 feet is short. That's fine. The main issue is "within the lot". The prompt says "Answer FAIL if the source text contradicts the statement, or simply does not say it." So FAIL is correct.

   Final check of the prompt: "Answer PASS only if every part of the statement


Here's a thinking process:

1.  **Analyze the Input:**
   - **Source Text:** "started as the Hotel Rosalie in 1897 … a one room hotel where patrons curled up in corners"
   - **Statement:** "Began as Hotel Rosalie (1897), where patrons slept en masse"
   - **Task:** Judge if the STATEMENT is fully supported by the SOURCE TEXT.
   - **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:* "Began as Hotel Rosalie (1897)" -> Matches "started as the Hotel Rosalie in 1897"
   - *Statement part 2:* "where patrons slept en masse" -> Source says "where patrons curled up in corners"
   - *Analysis of part 2:* "curled up in corners" implies a cramped, sparse, or makeshift sleeping arrangement, likely not "en masse" (which means in large numbers/groups together). Actually, "en masse" usually means all together or in a large group. The source says it was a "one room hotel where patrons curled up in corners". This suggests limited space, but does it support "slept en masse"? "En masse" implies a large group sleeping together. The source text doesn't explicitly say they slept en masse; it says they "curled up in corners". These are different descriptions. "Curled up in corners" suggests individual, cramped sleeping spots, not necessarily a mass gathering. More importantly, the source text does *not* state they slept "en masse". It just says they curled up in corners. The statement adds/changes the description to "slept en masse", which is not supported by the source. In fact, "one room hotel" + "curled up in corners" might imply crowding, but "en masse" is a specific claim not in the text. The prompt says: "Answer FAIL if the source text contradicts the statement, or simply does not say it."
   - Since the source text does not say patrons slept "en masse", and actually describes a different scenario ("curled up in corners"), the statement is not fully supported.

3.  **Determine Verdict:**
   - The statement claims patrons "slept en masse".
   - The source says patrons "curled up in corners".
   - These are not equivalent. The source does not support "en masse". Therefore, FAIL.

4.  **Draft Explanation (one sentence):**
   The source text states that patrons "curled up in corners" in a one-room hotel, which does not support the claim that they slept "en masse."

5.  **Check Constraints:**
   - JSON format? Yes.
   - Verdict exactly PASS/FAIL/UNCERTAIN? FAIL.
   - Why exactly one sentence? Yes.
   - Judge from source alone? Yes.
   - Matches criteria? Yes.

   Final check of the text: "started as the Hotel Rosalie in 1897 … a one room hotel where patrons curled up in corners" vs "Began as Hotel Rosalie (1897), where patrons slept en masse". The discrepancy is clear. "En masse" means all together or in a large group, while "curled up in corners" implies scattered, cramped individual spots. The source doesn't support "en masse". Verdict: FAIL.

   Could "curled up in corners" imply sleeping? Yes, but "en masse" is the key mismatch. The prompt says "Answer FAIL if the source text contradicts the statement, or simply does not say it." It definitely doesn't say it. So 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:** "the building is distinctive because it was never moved from its original location, unlike so many other buildings in Skagway … rebuilding the entire store based on historical evidence"
   - **Statement:** "The building has never been moved; the adjoining Red Front is a 2000 reconstruction"
   - **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.  **Deconstruct Statement:**
   - Part 1: "The building has never been moved"
   - Part 2: "the adjoining Red Front is a 2000 reconstruction"

3.  **Compare with Source Text:**
   - Source says: "the building is distinctive because it was never moved from its original location" -> Matches Part 1.
   - Source says: "… rebuilding the entire store based on historical evidence" -> Mentions rebuilding, but does *not* mention "adjoining Red Front", does *not* mention "2000", and does *not* explicitly link the rebuilding to the Red Front or specify the year.
   - Therefore, Part 2 is completely absent from the source text.

4.  **Determine Verdict:**
   - Since Part 2 is not in the source text, the statement is not fully supported.
   - Verdict: FAIL.

5.  **Draft Explanation (one sentence):**
   - The source text confirms the building was never moved, but it does not mention the adjoining Red Front or state that it was reconstructed in 2000.
   - Check constraints: "one sentence", matches requirement.

6.  **Format Output:**

   - Source Text: "one of the last inductees"
   - Statement claims: Harding visited Skagway on a specific date, spoke at a specific place, became the *final* man ever inducted, and died three weeks later.
   - Comparison: The source text only says "one of the last inductees". It does not mention Harding, Skagway, July 11, 1923, Pullen House, Arctic Brotherhood, or his death. It also says "one of the last" which contradicts "final man ever" (though the main issue is the massive lack of information).
   - Conclusion: The source text does not support the statement at all. It's completely absent. Therefore, FAIL.

     - 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)

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.✅

   - 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 constraint: "one sentence" -> Yes.
   - 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."

Here's a thinking process:

1.  **Analyze User Input:**
   - **Task:** Judge if the STATEMENT is fully supported by the SOURCE TEXT.
   - **Source Text:** "perhaps the most photographed building in Alaska,"
   - **Statement:** "The most photographed building in Alaska"
   - **Rules:**
     - PASS: Every part stated or necessarily follows.

     - UNCERTAIN: Too thin to tell.
     - Judge from source text alone.
     - 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.
   All constraints met. Output matches request.✅

   Done.
   [Output Generation] -> `{"verdict": "PASS", "why": "The source text explicitly identifies the establishment as Alaska's oldest hotel and states that it closed in 2002."}` (or similar one-sentence justification) -> I'll make it concise.


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"`

     - 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.

   - 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.
   - Output Generation.

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:**
   ```json
   {"verdict": "PASS", "why": "The source text explicitly confirms the dimensions, painting dates, and commissioner of Kirmse's Clock exactly as stated."}
   ```

   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:
   Wait, let's double check the exact wording. "50 ft wide × 75 ft tall" vs "75 feet high and 50 feet wide". Matches.
   "painted 1898–1900" vs "painted on the rock face between 1898 and 1900". Matches.
   "commissioned by jeweler Peter Kern" vs "Initially commissioned by Skagway jeweler Peter Kern". Matches.
   Everything is directly supported. Verdict is PASS.
   Output matches requested format.✅
   Proceed.
   Output Generation.
   `{"verdict": "PASS", "why": "The source text explicitly confirms the dimensions, painting dates, and commissioner of Kirmse's Clock exactly as stated."}` -> matches requirements.✅
   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.
   "Reply with a single JSON object and nothing else, exactly this shape:" -> Yes.
   All constraints met.✅
   Output matches.
   [Done]
   *Self-Correction/Verification during generation prep*:
   I will ensure the JSON is strictly formatted as requested. No extra text. One sentence for "why". Verdict is PASS. All good.
   Proceeds.
   Output Generation.
   `{"verdict": "PASS", "why": "The source text explicitly confirms the dimensions, painting dates, and commissioner of Kirmse's Clock exactly as stated."}` -> ready.
   [Output Generation] -> *Proceeds*
   *(Note: I'll make sure the JSON is perfectly formatted without markdown if possible, but the prompt says "Reply with a single JSON object and nothing else", so I will output raw JSON or markdown JSON, both are fine, but I'll stick to raw JSON to be safe, or standard markdown. The prompt says "exactly this shape", I'll just output the JSON string.)*
   Actually, I'll output just the JSON object as requested.

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.
   - Output matches exactly.✅
   - Proceed.
   - Output generation.
   - `{"verdict": "FAIL", "why": "The source text explicitly describes a high school offering college-preparatory curriculum, which contradicts the statement's claim that it is an institution of higher education."}` (Slightly refined for precision) -> matches constraints.✅
