It is difficult and costly to extract sugar from low-purity juices
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The exact statement 'It is difficult and costly to extract sugar from low-purity juices' appears verbatim in the second paragraph, confirming all elements of the claim including the subject, predicate, and context.
- 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 general knowledge about sugar manufacturing, not attributed to a named source). The stance 'asserts' is appropriate as the passage states this as fact. The sentiment 'negative' accurately reflects the unfavorable connotation of 'difficult and costly'. The time qualifiers are correctly null since the passage provides no temporal scope. The context 'in sugar manufacturing' is appropriate and matches the passage's discussion. The quote is verbatim from the passage and directly supports the claim.
the extraction in the small, crude mills is poor
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'the extraction in the small, crude mills is poor' appears verbatim, making this a fully supported assertion with no rewording needed.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (implicit authorial assertion), the stance is 'asserts' (the passage states this as fact, not disputed), the sentiment is appropriately 'negative' (the word 'poor' conveys negative connotation), the time is null as the passage provides no temporal scope, the context is empty as none is specified in the passage, and the quote 'the extraction in the small, crude mills is poor' appears verbatim and directly supports the claim.
the extraction of sugar equals 8½ per cent of the weight of the cane
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'the extraction of sugar equals 8½ per cent of the weight of the cane.' The quote provided matches the text exactly, and the subject-predicate-object relationship is fully grounded in the source material.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage does not attribute this statement to a named source). The stance is properly marked as 'asserts' (the passage presents this as a factual statement, not disputed or questioned). The sentiment is neutral, matching the objective, technical tone of the passage. The time qualifiers are correctly set to null since the passage provides no temporal scope for this claim. The context is appropriately empty as the passage does not restrict the claim to a particular sense or role. The quote matches verbatim from the passage and directly supports the claim about sugar extraction equaling 8½ per cent of the weight of cane.
the amount of sugar extracted since 1904 averaged 10.95 per cent of the weight of the cane
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage with identical wording: 'the amount of sugar extracted since 1904 averaged 10.95 per cent of the weight of the cane.' All elements including the subject, predicate, object, and temporal scope 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 makes this assertion, not citing a named source). The stance of 'asserts' matches the passage's declarative presentation. The sentiment is neutral, consistent with the factual tone. The time qualifiers are accurate: 'when' is 'since 1904', 'valid_from' is 1904, and 'valid_to' is null (the passage provides no end date). The context 'since 1904' correctly reflects the temporal restriction stated in the passage. The quote is verbatim from the passage and directly supports the claim.
the residue is sold as molasses
judge verdicts (2)
- groundedness 0.90 pass — The claim is directly supported by the passage, which explicitly states 'the residue is sold as molasses' after describing the repeated reboiling and extraction process. The passage clearly establishes molasses as a residue product from sugar extraction with only minor conceptual rewording needed to match the claim's phrasing.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to 'author' (the passage describes the sugar extraction process without naming a specific source). The stance is appropriately 'asserts' - the passage states factually that molasses is the residue. Sentiment is neutral, matching the objective, technical tone of the passage. Time qualifiers are correctly null since no temporal scope is specified. Context is empty, which is appropriate as the passage does not restrict molasses to a particular sense or role when introducing it as residue. The quote 'the residue is sold as molasses' appears verbatim and directly supports the claim.
