The leaves are lanceolate, or lance-shaped
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage's opening sentence: 'The leaves are lanceolate, or lance-shaped, being borne in pairs opposite each other.' The exact language from the passage is used, making this fully grounded.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (descriptive botanical text). The stance is 'asserts' which matches the passage's declarative presentation. The sentiment is neutral, appropriate for factual description. The time qualifiers are all null, correctly reflecting that the passage provides no temporal scope. The context is empty, which is appropriate since the passage discusses the physical characteristics of coffee leaves without restricting to a particular sense or role. The quote is verbatim from the passage and directly supports the claim about lanceolate leaf shape.
being borne in pairs opposite each other
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'The leaves are lanceolate, or lance-shaped, being borne in pairs opposite each other.' This explicitly confirms that coffee leaves are borne in pairs opposite each other.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage presents this as descriptive botanical fact without naming a specific source). The stance is appropriately 'asserts' as the passage states this as a factual observation. Sentiment is neutral, matching the technical, descriptive tone of the passage. Time qualifiers are all null, which is correct since the passage provides no temporal scope. Context is empty, appropriate since the passage does not restrict this claim to a particular sense or role. The quote 'being borne in pairs opposite each other' appears verbatim in the opening sentence and directly supports the claim.
They are three to six inches in length
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'They are three to six inches in length' explicitly describes the length measurement of coffee leaves with no rewording or interpretation needed.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly identified as 'author' since the passage presents this as descriptive botanical information without attribution to a named source. The stance 'asserts' is appropriate for the declarative statement. The sentiment 'neutral' matches the objective, technical tone. Time qualifiers are correctly null as the passage provides no temporal scope. Context is appropriately empty as the passage does not restrict the claim to a particular sense or role. The quote 'They are three to six inches in length' appears verbatim and directly supports the claim about coffee leaf length measurements.
The coffee leaves are thin, but of firm texture, slightly coriaceous
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'The coffee leaves are thin, but of firm texture, slightly coriaceous.' This is an exact match to the source material with no added interpretation or outside knowledge required.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (passage presents this as descriptive fact). The stance is appropriately 'asserts' (not disputed or questioned). The sentiment is neutral, matching the objective botanical description. Time qualifiers are correctly null since the passage provides no temporal scope. Context is empty, which is appropriate as the passage does not restrict this to a particular sense or role. The quote appears verbatim in the passage and directly supports the claim.
They are very dark green on the upper surface
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'They are very dark green on the upper surface' explicitly describes the color of coffee leaves on their upper surface.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to 'author' (the passage is descriptive text without attribution to a named source). The stance 'asserts' matches the declarative nature of the statement. Sentiment is neutral, appropriate for botanical description. Time qualifiers are all null, correctly reflecting that the passage provides no temporal information. Context 'upper surface' accurately reflects the passage's restriction of the dark green color to that specific part of the leaf. The quote appears verbatim and directly supports the claim.
but much lighter underneath
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'They are very dark green on the upper surface, but much lighter underneath.' This explicitly describes the coffee leaves as being much lighter on their lower (underneath) surface compared to the upper surface.
- qualifier_fidelity 0.80 pass — The claim is largely faithful to the passage. The quote appears verbatim and accurately supports the predicate. Viewpoint, stance, sentiment, and time are all appropriate. However, there is a minor inconsistency: the context field uses 'underneath' as a descriptor, but the passage's actual contextual framing is that the leaves are 'much lighter underneath' referring to the underside of the leaf surface. The context should more precisely reflect that this describes the lower/under surface characteristics, though 'underneath' captures the essential meaning from the passage. All other qualifiers are faithful.
the natives brew a coffee tea from the leaves of the coffee tree
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'In some tropical countries the natives brew a coffee tea from the leaves of the coffee tree.' The subject, predicate, and object are all explicitly presented without requiring outside knowledge or over-generalization.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. Viewpoint, stance, sentiment, time, and context all match the passage accurately. The quote appears verbatim in the passage and supports the claim. Minor deduction: the passage states this practice occurs "in some tropical countries," which could be interpreted as adding a slight qualifier ("some") that isn't explicitly captured in the context field, though "tropical countries" as context is not incorrect.
