The flowers are also tubular, the tube of the corolla dividing into five white segments.
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'The flowers are also tubular, the tube of the corolla dividing into five white segments.' This matches the subject (coffee flower), predicate (have tubular corolla dividing into five white segments), and object (white segments) exactly as presented in the quoted text.
- qualifier_fidelity 0.90 pass — The claim is faithful to the passage across all qualifiers. The quote accurately supports the predicate about tubular corolla with five white segments. Viewpoint, stance, sentiment, time (null), and context are all appropriate. Minor deduction (0.1) because the passage introduces this information descriptively without explicitly attributing it to a named source or the author, though in this descriptive context, treating it as author assertion is reasonable rather than requiring explicit attribution. All qualifiers are faithful enough to meet the passing threshold.
the usual color of the coffee flower is white
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage with the exact quote provided: 'While the usual color of the coffee flower is white, the fresh stamens and pistils may have a greenish tinge, and in some cultivated species the corolla is pale pink.' This explicitly confirms that white is the usual color of the coffee flower.
- qualifier_fidelity 0.90 pass — The claim is nearly faithful to the passage. However, the viewpoint should be 'passage' or left as stated text rather than 'author' since the passage does not attribute this statement to a named source or specific author—it is presented as general fact/description by the passage itself. The quote is accurate and verbatim, stance is correctly 'asserts', sentiment is neutral, time qualifiers are appropriately null, and context is empty as appropriate. Minor deduction for the viewpoint specification.
