judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'As far as the American coffee trade is concerned, the first sensational upheaval took place in 1880-81.' The subject, predicate, and object are all explicitly mentioned with no additional inference required.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (not a named source). The stance is 'asserts' which matches the passage's direct statement. The sentiment is 'negative' which is appropriate given 'upheaval' and 'collapse' language. The time qualifiers (when: 1880-81, valid_from: 1880, valid_to: 1881) are exact matches. The context is empty, which is appropriate since the passage provides no specific sense restriction. The quote appears verbatim and directly supports the claim.
