The centrals usually raise about one-half of the cane they grind
judge verdicts (2)
- groundedness 1.00 pass — This claim is directly stated in the passage: 'The centrals usually raise about one-half of the cane they grind.' The wording matches the passage exactly and requires no interpretation or outside knowledge.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage presents this as factual information without attributing it to a named source). The stance is accurately 'asserts' as the passage states this as fact. The sentiment is neutral, matching the passage's objective tone. The time qualifiers are appropriately null since the passage provides no specific temporal scope for this claim. The context is empty as appropriate since no specific sense or role restriction applies. The quote matches verbatim and directly supports the claim.
The rest they buy from the _colono_
judge verdicts (2)
- groundedness 0.95 pass — The claim is directly supported by the passage, which explicitly states 'The centrals usually raise about one-half of the cane they grind. The rest they buy from the _colono_.' The subject, predicate, and object are all clearly stated without requiring outside knowledge or over-generalization.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (implicit narration), the stance is appropriately 'asserts' for a straightforward factual statement, sentiment is neutral, time is correctly null (no specific temporal restriction given), context is empty (appropriate as no specific sense restriction applies), and the quote 'The rest they buy from the _colono_' appears verbatim and accurately supports the claim about central factories purchasing cane from colonos.
the price paid to the _colono_ for his cane is 5 per cent of the weight of the cane in sugar
judge verdicts (2)
- groundedness 0.70 pass — The passage states that 'the price paid to the _colono_ for his cane is 5 per cent of the weight of the cane in sugar.' The claim rewords this as 'central factories pay to colono 5 per cent of the weight of the cane in sugar,' which is a minor rewording that accurately captures the stated information, though it slightly personalizes the agent (central factories) where the passage speaks more generally about price paid.
- qualifier_fidelity 0.95 pass — Claim is highly faithful to passage. All qualifiers are correct: viewpoint is 'author' (passage presents as factual statement, not attributed source), stance is 'asserts' (appropriate for declarative statement), sentiment is 'neutral' (passage is factual/informational), time is null (passage provides no temporal scope for this practice), context is empty (appropriate as passage gives no qualifying context), and quote is verbatim. Minor deduction (0.05): The passage adds "As a rule" qualifier and notes "this is subject to modification at times," which slightly moderates the absoluteness of the claim's assertion. The claim could have reflected this hedging language more explicitly, though the core statement remains faithful.
they are equipped with the newest and best machinery
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'As the central factories are of recent construction, they are equipped with the newest and best machinery and the most scientific methods govern their operation.' The exact phrase 'equipped with the newest and best machinery' appears verbatim, making this fully grounded.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage presents this as a factual statement, not attributed to a named source). The stance 'asserts' is appropriate as the passage makes a direct declarative claim. The sentiment is positive, matching the connotation of 'newest and best'. The time is correctly null as the passage does not specify when this equipment status applies, only that the factories are 'of recent construction'. The context 'of recent construction' is faithful and appears in the preceding sentence. The quote appears verbatim in the passage and directly supports the claim.
Two mills were operated on the new plan as an experiment with such marked success
judge verdicts (4)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Two mills were operated on the new plan as an experiment with such marked success that an act was passed in 1893.' The passage explicitly confirms that central factories (mills) were operated as an experiment with marked success, supporting all key elements of the claim.
- qualifier_fidelity 0.60 fail — The time qualifier is unfaithful. The passage states the two mills were operated 'as an experiment with such marked success' but does not specify when this occurred or provide an end date. The claim's 'valid_to: 1893' is not supported by the passage—1893 is when an act was passed to foster central-factory development, not when the experimental period ended. The 'when' should remain null and 'valid_to' should also be null, as the passage provides no temporal boundaries for the experimental period.
- groundedness 1.00 pass — The claim is directly supported by the passage. The exact quote provided matches the text: 'Two mills were operated on the new plan as an experiment with such marked success,' which explicitly states that central factories (two mills) were operated as an experiment with marked success.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage presents this as factual narrative, not attributed to a named source). The stance 'asserts' matches the passage's declarative presentation. The sentiment 'positive' accurately reflects the passage's positive framing of 'marked success'. The time is correctly null as the passage does not specify when the experiment occurred (only that it was before 1893). The context is appropriately empty as the passage does not restrict the claim to a particular sense. The quote is verbatim and directly supports the claim.
Almost all of the cane grown in Porto Rico is ground in the large central factories
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the opening sentence of the passage: 'Almost all of the cane grown in Porto Rico is ground in the large central factories.' The wording matches the source material precisely, with no added interpretation or outside knowledge required.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The quote is verbatim and accurate. The viewpoint, stance, and sentiment are appropriately set to 'author', 'asserts', and 'neutral' respectively. The context qualifier 'present time of writing' is reasonable given the passage discusses this as current practice without specifying an exact date. Minor deduction: the time qualifiers (when, valid_from, valid_to) are all null, which is appropriate since the passage does not provide specific temporal boundaries for this claim, though it does mention 'the last ten or twelve years' as when this practice began. This temporal reference could arguably warrant a valid_from date, but null is defensible given the passage doesn't give a precise start date.
the legislative assembly voted £50,000 for the establishing of central factories
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'In 1885 the industry appeared to be in danger of extinction, and, as a remedial measure, the legislative assembly voted £50,000 for the establishing of central factories.' All elements—subject, predicate, object, and time—are explicitly supported.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage itself states this fact without attribution to a named source). The stance is 'asserts' which matches the declarative nature of the passage. The sentiment is appropriately positive given that this was presented as 'a remedial measure' to address industry crisis. The time (1885) matches the passage exactly ('In 1885 the industry appeared to be in danger of extinction, and, as a remedial measure, the legislative assembly voted'). The context is empty, which is correct as the passage provides no specific contextual qualifier for this statement. The quote appears verbatim in the passage and directly supports the claim.
