only 0.087 percent of the alkaloid in the stems of the plant separated from the leaves
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The text explicitly states that 'Power and Chestnut found...only 0.087 percent of the alkaloid in the stems of the plant separated from the leaves,' confirming that coffee plant stems contain alkaloid at this concentration.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint correctly attributes the finding to Power and Chestnut (named sources, not generic author). The stance is properly marked as 'asserts' reflecting the passage's straightforward reporting. Sentiment is neutral, matching the objective, data-driven nature of the scientific finding. Time qualifiers are appropriately null since the passage provides no temporal information about when this research was conducted. Context correctly specifies 'separated from leaves,' which is explicitly stated in the passage and distinguishes this measurement from the leaves' alkaloid content (0.82 percent). The quote appears verbatim in the passage and accurately supports the claim about alkaloid content in plant stems.
