coffee-tannin, which is soluble in water at any temperature
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'coffee-tannin, which is soluble in water at any temperature and is governed by the time of contact.' The subject, predicate, and object are all explicitly present with no rewording necessary.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (general instructional text without named sources). The stance is 'asserts' which matches the declarative nature of the claim in the passage. The sentiment is neutral, appropriate for a factual statement about chemical solubility. The time qualifiers are all null, which is correct since the passage provides no temporal scope. The context is empty, which is appropriate as the passage does not restrict the claim to a specific sense or period. The quote appears verbatim in the passage and accurately supports the claim about coffee-tannin's solubility properties.
- coffee-tannin is eliminated to practically nothing coffee-tannin presence ⟨in quick brewing methods⟩
Coffee-tannin, which is not the commercial tannic acid, is eliminated to practically nothing in the quick brewing methods
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The exact sentence 'Coffee-tannin, which is not the commercial tannic acid, is eliminated to practically nothing in the quick brewing methods' appears verbatim, fully supporting all elements of the claim.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (implicit in the text's instructional tone). The stance is 'asserts' as the passage makes a direct statement without dispute or question. The sentiment is appropriately positive regarding the elimination of an undesirable element. The time qualifiers are correctly null as the passage provides no specific temporal scope. The context 'in quick brewing methods' accurately reflects the passage's restriction of the claim. The quote appears verbatim and directly supports the claim.
draws out undesirable elements, such as coffee-tannin, which is soluble in water at any temperature and is governed by the time of contact
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly says 'The effort to make up this deficiency by longer contact of coffee and water, or repeated pouring through, results in no extraction of the oils, but draws out undesirable elements, such as coffee-tannin.' This fully supports the claim that prolonged contact or repeated pouring draws out undesirable elements including coffee-tannin.
- qualifier_fidelity 0.95 pass — The claim is highly faithful to the passage. The quote appears verbatim and accurately captures the passage's assertion that prolonged contact/repeated pouring draws out undesirable elements like coffee-tannin. All qualifiers are correct: viewpoint is 'author' (the passage presents this as factual statement, not attributed to a named source), stance is 'asserts' (the passage states this as fact, not disputed), sentiment is 'negative' (undesirable elements is clearly pejorative), time is null (passage provides no temporal scope), and context is empty (appropriate, as the passage gives no contextual restriction). Minor deduction only for slight semantic precision: the passage discusses this as a result of attempting to compensate for weak extraction, though this does not materially affect the claim's fidelity.
