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."}`
   - Ensure it's exactly one sentence for "why".
   - 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.

5.  **Format Output:**
   - Must be exactly: `{"verdict": "PASS", "why": "The source text explicitly states both the date of the murder and that Mike shot her in the back, fully supporting the statement."}`
   - Check constraints: single JSON object, nothing else, exact shape, verdict is PASS/FAIL/UNCERTAIN, why is one sentence.

   All constraints met. Proceed.
   Self-Correction/Refinement during thought:
   Check exact wording of source: "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."
   Matches perfectly. Verdict: PASS.
   Why sentence: The source text explicitly confirms both the date of the murder and that Mike shot her in the back. (One sentence)
   JSON format matches requirement.
   Ready.✅
   Output matches response.
   Proceeds.

   All constraints satisfied. Output matches.
   Proceeds.
   [Output Generation] -> `{"verdict": "PASS", "why": "The source text explicitly states both the date of the murder and that Mike shot her in the back, fully supporting the statement."}` (adjusted slightly for flow, still one sentence) -> matches.
   Final check of the prompt: "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." -> Direct match. PASS.
   Output matches exactly.✅
   Proceeds.
   [Output Generation] (matches the final refined version)
   `{"verdict": "PASS", "why": "The source text explicitly states both the date of the murder and that Mike shot her in the back, fully supporting the statement."}` -> valid JSON, one sentence why, correct verdict. All good.

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


Here's a thinking process:

1.  **Analyze the User Input:**
   - **Task:** Judge if the STATEMENT is fully supported by the SOURCE TEXT.
   - **Source Text:** "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"
   - **Statement:** "Packer Jack" Newman commissioned the bronze (sculptor James A. Wehn) and it was unveiled in 1930, 28 years after her death.
   - **Rules:** PASS if fully supported/necessarily follows. FAIL if contradicted or not stated. UNCERTAIN if too thin. Judge *only* from source text. World knowledge doesn't count. Output JSON with verdict and why.

2.  **Deconstruct the Statement:**
   - Claim 1: "Packer Jack" Newman commissioned the bronze.
   - Claim 2: Sculptor is James A. Wehn.
   - Claim 3: It was unveiled in 1930.
   - 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

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.

     - "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.

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`.

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.

   Construct JSON.✅

   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.

1.  **Analyze User Input:**
   - **Task:** Judge if the STATEMENT is fully supported by the SOURCE TEXT.
   - **Source Text:** `one of the last inductees`

2.  **Evaluate Source Text vs. Statement:**
   - 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.

3.  **Formulate Response:**
   - Verdict: FAIL

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.

   - 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."}`

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.
   - **Source Text:** "Ship's Register by Moore's Wharf began to be developed in the teens, perhaps earlier"
   - **Statement:** "Crews have been "autographing" the wall since 1928"

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.
     - FAIL if contradicted or not stated.
     - UNCERTAIN if too thin to tell.
     - 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."
