  judge verdicts (2)

  • groundedness 1.00 pass — The claim is directly supported by the passage. The exact quote provided matches verbatim from the text: 'A 2020 follow-up study definitively confirmed that the vast majority of Coffea arabica plants originate from early varieties in the coffee farms of Yemen.' All elements of the claim—the subject (Coffea arabica), the predicate (originates from early varieties in), the object (coffee farms of Yemen), and the temporal context (2020)—are explicitly stated in the passage.
  • qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The quote is verbatim and accurately cited. The time qualifier (2020) correctly reflects when the study was conducted. The context qualifier appropriately captures 'vast majority of plants' from the passage. The sentiment (neutral) and stance (asserts) are appropriate for a factual research finding. Minor deduction only: the viewpoint is labeled 'author' but the passage attributes this to 'A 2020 follow-up study' - a named source. However, since the passage itself presents this as established fact in the narrative without naming a specific researcher or institution, treating it as the author's presentation is reasonable and does not materially misrepresent the qualifier's fidelity.
