judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly says Rio coffee was carried 'up to eleven and one-half cents late in November' in the New York market, making this a peak price that matches the claim's subject, predicate, object, timing, and context precisely.
- qualifier_fidelity 0.90 pass — All qualifiers are faithful to the passage. The viewpoint, stance, and sentiment are appropriate; the time specification (late November 1883) is accurate; the context (New York market) is correctly identified from 'in this market'; and the quote is verbatim and supports the claim. Minor note: the quote could be more complete ('up to eleven and one-half cents late in November') but the selected portion is accurate and sufficient.
