- Lahaina cane proved profitable to raise Lahaina cane fifteen or sixteen years after 1854-1855
The latter proved to be profitable to raise
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The text explicitly states 'The latter proved to be profitable to raise' referring to Lahaina cane, and confirms it began displacing other species 'fifteen or sixteen years later,' which aligns with the specified timeframe of 1869-1871.
- qualifier_fidelity 0.85 pass — Most qualifiers are faithful. Viewpoint correctly uses 'author' since the passage itself presents this assessment. Stance 'asserts' and sentiment 'positive' both match the passage's framing. Time calculation is reasonable: 'fifteen or sixteen years later' after 1854-1855 yields 1869-1871, though the passage phrases this prospectively rather than providing exact dates. The quote is accurate and verbatim. Minor deduction: the claim's 'time' object specifies a narrow range (1869-1871) when the passage only provides a relative timeframe ('fifteen or sixteen years later'), making the normalized dates somewhat more precise than the source warrants, though this is a reasonable interpretation rather than an outright error.
- Lahaina cane began to displace other species fifteen or sixteen years after 1854-1855 ⟨Hawaiian islands⟩
fifteen or sixteen years later began to displace other species throughout the islands
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The text explicitly states that Lahaina cane 'proved to be profitable to raise and fifteen or sixteen years later began to displace other species throughout the islands,' which matches the claim's subject, predicate, and object exactly with proper temporal contextualization.
- qualifier_fidelity 0.90 pass — Nearly all qualifiers are faithful to the passage. The viewpoint, stance, sentiment, context, and quote are all accurate. The time calculation is reasonable (15-16 years after 1854-1855 yields 1869-1871), though the passage itself provides only the relative timeframe without specifying exact normalized dates. Minor note: the passage does not explicitly attribute this observation to a named source, so "author" is appropriate, though the passage reads as historical narrative rather than authored analysis. All major qualifiers check out against the passage text.
- Lahaina cane was the variety most in favor Hawaiian plantations up to twenty years ago ⟨up to twenty years ago⟩
it was the variety most in favor on all Hawaiian plantations
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'up to twenty years ago it was the variety most in favor on all Hawaiian plantations.' The subject, predicate, object, and temporal qualifier all match the source text precisely without any rewording or inference required.
- qualifier_fidelity 0.85 pass — The claim is largely faithful to the passage. The viewpoint, stance, and sentiment are all appropriate - the passage presents this as factual assertion with positive connotation. The temporal qualifier 'up to twenty years ago' correctly reflects the passage's phrasing. However, there is a minor issue with the 'context' field: it should be empty or null rather than restating the time qualifier, since the passage does not restrict the claim to a particular sense or role of Lahaina cane - it refers to the variety itself without contextual restriction. The quote is accurate and supports the claim.
In 1898 Lahaina and Rose Bamboo seemed to have outlived their usefulness on the Hamakua coast
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage, which explicitly states 'In 1898 Lahaina and Rose Bamboo seemed to have outlived their usefulness on the Hamakua coast of the island of Hawaii.' The subject, predicate, object, and time are all clearly stated in the source text without requiring outside knowledge or over-generalization.
- qualifier_fidelity 0.85 pass — One minor issue: The claim uses 'viewpoint': 'author', but the passage uses the attribution phrase 'seemed to have outlived' which conveys the author's qualified observation rather than a direct attribution to a named source. This is acceptable as 'author' - the passage does not attribute this to a specific named source, so 'author' is appropriate. The quote is accurate and verbatim. The stance 'asserts' is correct - the passage presents this as fact without dispute framing. The sentiment 'negative' is appropriate given the context of usefulness being outlived. The time qualifier correctly reflects 1898 as stated in the passage. The context is empty, which is appropriate since the passage does specify a geographic restriction (Hamakua coast) but this is already captured in the 'object' of the claim. Overall, all qualifiers are faithful to the passage.
brought from Tahiti two varieties of cane, one known as Cuban and the other as Lahaina
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage, which explicitly states that 'Captain Edwards of the American whaler _George Washington_ brought from Tahiti two varieties of cane, one known as Cuban and the other as Lahaina' in the year 1854 or 1855.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The viewpoint, stance, sentiment, time qualifiers, and quote are all accurate and properly sourced to the author's account of Captain Edwards' actions. Minor note: the quote includes the Cuban variety mention which is not strictly necessary to support the claim about Lahaina, but this is not an error—the quote is verbatim and does support the claim. The context is appropriately left empty as the passage provides no specific sense restriction.
- Rose Bamboo cane compared in productiveness with Lahaina cane 1880 ⟨high altitudes⟩
of these only one—the Rose Bamboo—compared with the Lahaina in productiveness, and that only in high altitudes
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly says that of the twelve varieties imported from Queensland in 1880, 'only one—the Rose Bamboo—compared with the Lahaina in productiveness, and that only in high altitudes,' which precisely matches the subject, predicate, object, time, and context specified in the claim.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The quote is verbatim, the context "high altitudes" is correctly specified, the perspective viewpoint and stance are appropriate, and the temporal reference to 1880 (when the varieties were imported) is accurate. The only minor imprecision is the time object: the passage does not specify an end date for this comparison, so valid_to should remain null (which it does), and the "when" field of 1880 correctly reflects the import date mentioned in the passage, making this a strong claim overall.
