judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The text explicitly states that 'when once the plantation begins to yield, the crop is as large as that of _Coffea arabica_, and occasionally somewhat larger,' which directly matches the subject-predicate-object relationship in the claim.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author who presents the comparison. The stance is properly marked as 'asserts' since the passage states this as fact. Sentiment is neutral, matching the objective tone of the comparison. The time qualifier accurately captures the temporal scope ('when once the plantation begins to yield') as stated in the passage. The context 'when mature' appropriately reflects the passage's restriction to the post-maturation period. The quote is verbatim and directly supports the claim about yield comparison.
