judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The quoted sentence explicitly asserts that 1880 was notable for failures in the American coffee trade as a result of syndicate planting and speculative buying of coffees in Brazil, Mexico, and Central America. All elements of the claim are fully supported by the passage.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly identified as 'author' since the passage presents this as a historical statement without attribution to a named source. The stance 'asserts' is appropriate as the passage states this factually. The sentiment 'negative' correctly reflects the negative connotation of 'failures.' The time qualifier accurately captures 1880 as specified in the passage, with valid_from matching and valid_to as null since no end date is provided. The context is appropriately empty as the passage does not restrict the claim to a particular sense or role. The quote is verbatim and directly supports all elements of the claim.
Great failures in the American coffee trade as a result of syndicate planting and buying of coffees in Brazil, Mexico, and Central America
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The 1880 entry explicitly states 'Great failures in the American coffee trade as a result of syndicate planting and buying of coffees in Brazil, Mexico, and Central America,' which precisely matches the subject, predicate, time period, and supporting context provided in the claim.
- qualifier_fidelity 0.90 pass — Nearly all qualifiers are faithful to the passage. The quote is verbatim and supports the claim. The time (1880), sentiment (negative), and stance (asserts) all match the passage. The viewpoint is correctly attributed to the author rather than a named source. The context is appropriately empty since the passage provides no contextual restriction. One minor deduction: the predicate 'experiences great failures' is slightly rephrased from the passage's 'Great failures in the American coffee trade', though this is a negligible semantic variation and the meaning is preserved.

The context is appropriately empty as none is specified in the passage. The quote is verbatim and directly supports the claim.
