a little less productive than the _Coffea arabica_
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly describes Purpurescens as "a little less productive than the _Coffea arabica_", which exactly matches the subject-predicate-object relationship presented in the claim.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage makes a direct descriptive statement without attribution to a named source). The stance is correctly marked as 'asserts' rather than disputes or questions. The sentiment is neutral, matching the objective descriptive tone of the passage. Time qualifiers are appropriately null since the passage provides no temporal information. Context is empty, which is appropriate as the passage does not restrict the claim to a particular sense or role. The quote appears verbatim in the passage and directly supports the claim about Purpurescens being less productive than Coffea arabica.
