In 1856 no fertilizers were used
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'In 1856 no fertilizers were used and practically nothing was known of irrigation.' The subject, predicate, and object are all explicitly supported 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 (the passage presents this as historical fact without attribution to a named source). The stance is appropriately 'asserts' as a factual statement. The sentiment is neutral, matching the passage's objective tone. The time qualifier correctly identifies 1856 as specified in the passage, with valid_from matching and valid_to correctly set to null since the passage provides no end date. The context is appropriately empty as the passage does not restrict this claim to a particular sense or role. The quote 'In 1856 no fertilizers were used' appears verbatim in the passage and directly supports the claim.
practically nothing was known of irrigation
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage, which explicitly states 'In 1856 no fertilizers were used and practically nothing was known of irrigation.' This directly confirms that irrigation was practically unknown in Hawaiian sugar cane cultivation in 1856.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The quote 'practically nothing was known of irrigation' appears verbatim and supports the claim. The viewpoint is correctly attributed to the author (narrative voice), stance is appropriately 'asserts', sentiment is neutral as the passage states this as a factual historical observation. Time is correctly set to 1856 with valid_from matching the passage's temporal reference. Context is empty, which is appropriate since the passage does not restrict the claim to a specific sense or role. The time qualifier uses valid_to as null, which is consistent with the passage's statement about 1856 without specifying an endpoint for when this condition changed.
