Viehoever and Lepper carried on a series of cup tests of _robusta_
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage with the exact quote provided: 'Viehoever and Lepper carried on a series of cup tests of _robusta_'. This is a straightforward factual assertion with no rewording needed.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The subject, predicate, and object are accurately drawn from the text. The quote is verbatim. The perspective (author asserting neutrally) is appropriate as the passage directly states this fact without attribution to a named source or dispute. Time qualifiers are correctly null as the passage provides no specific temporal information. However, there is a minor issue: the context field is empty when it could specify this refers to coffee/the robusta variety's sensory/culinary properties, though this is not critical since the object already specifies 'robusta'. Overall, all major qualifiers are faithful to the passage.
