Coffee-tannin, which is not the commercial tannic acid
judge verdicts (4)
- groundedness 1.00 pass — The claim is directly stated in the passage with the exact quote 'Coffee-tannin, which is not the commercial tannic acid,' making it fully supported without requiring outside knowledge or over-generalization.
- qualifier_fidelity 0.50 fail — The claim has two unfaithful qualifiers: (1) STANCE: The passage makes a straightforward factual distinction ('is not'), not a dispute or questioning; the stance should be neutral/assertive, not 'disputes'. (2) VIEWPOINT: The passage does not attribute this statement to a named source or author; it presents it as objective fact. Using 'author' as viewpoint is incorrect when the passage makes an unattributed scientific claim. The quote is accurate and the other qualifiers (sentiment, time, context) are correctly faithful.
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Coffee-tannin, which is not the commercial tannic acid, is eliminated to practically nothing in the quick brewing methods.' The subject-predicate-object relationship is explicitly asserted without requiring outside knowledge or interpretation.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the passage itself. The stance is appropriately 'asserts' rather than disputes. The sentiment is neutral, matching the factual tone of the passage. The time qualifiers are null as the passage provides no temporal context. The context is empty as appropriate since no specific sense restriction is stated. The quote appears verbatim in the passage and directly supports the claim about coffee-tannin's distinction from commercial tannic acid.
