he found 0.9 percent caffein, a reducing sugar, caffetannic acid, and phytosterol
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage, which explicitly states that Graf examined flowers from 20-year-old coffee trees and found phytosterol among other compounds. The subject, predicate, and object are all clearly stated without requiring outside knowledge or generalization.
- qualifier_fidelity 0.75 pass — The claim is largely faithful with minor qualifier issues. VIEWPOINT: Correctly attributed to 'Graf' as the passage states 'One of the few chemical investigations of the growing tree is the examination by Graf.' STANCE and SENTIMENT: Correctly marked as 'asserts' and 'neutral' - the passage presents Graf's findings factually. TIME: Correctly marked as null since the passage provides no date for Graf's examination. CONTEXT: Appropriately specifies '20-year-old coffee trees' matching the passage 'flowers from 20-year-old coffee trees.' QUOTE: The quote is verbatim from the passage and supports the claim. However, there is a minor issue: the quote includes multiple substances ('caffein, a reducing sugar, caffetannic acid, and phytosterol') but the claim's predicate isolates only phytosterol. While this is not technically unfaithful to qualifiers, the selective extraction of one item from Graf's findings without the full list slightly misrepresents the scope of his findings, though the claim itself remains supported by the passage.
