judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Bourbon cane is the variety principally grown.' The subject, predicate, and object are all explicitly presented without any rewording or outside knowledge required.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly identified as 'author' since the passage itself makes the assertion without attributing it to a named source. The stance 'asserts' accurately reflects the declarative nature of the statement. The sentiment is appropriately neutral. The time qualifiers are correctly null since the passage provides no temporal scope. The context 'Guadeloupe and Martinique' is faithful to the passage's opening discussion of sugar plantations in these locations. The quote appears verbatim in the passage and directly supports the claim about Bourbon cane being the principal variety grown.

judge verdicts (2)

- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (implicit narrator). The stance is appropriately 'asserts' as the passage states this as fact. The sentiment is neutral, matching the passage's factual tone. The time qualifier accurately reflects the passage's temporal scope ('up to this time' referring to 1875, with valid_to set to 1875). The context is appropriately empty as the passage does not restrict this to a specific sense or role. The quote is verbatim from the passage and directly supports the claim about Bourbon cane being the generally grown variety until 1875.
the growers to substitute it and other sturdy species of cane for the Bourbon
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The text explicitly states: 'The hardiness of this variety encouraged the growers to substitute it and other sturdy species of cane for the Bourbon.' This directly confirms that growers substituted sturdy species for Bourbon cane after the 1875 rust disease.
- qualifier_fidelity 0.90 pass — All qualifiers are faithful to the passage. The viewpoint is correctly identified as 'author' (the passage presents this as historical fact without attribution to a named source). The stance 'asserts' is appropriate for the straightforward factual presentation. The sentiment 'positive' accurately reflects the passage's framing that the substitution "proved entirely successful and the planters enjoyed good times once more." The time qualifier correctly uses "after 1875" with valid_from set to 1875, matching the passage's chronology. The context is appropriately empty as the passage does not restrict the claim to a specific sense or role. The quote is verbatim and supports the claim. Minor note: valid_to is null, which is correct since the passage provides no end point for this practice.
