It was in 1711 that the infusion idea in coffee making appeared in France
judge verdicts (4)
- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly says 'It came in the form of a fustian (cloth) bag which contained the ground coffee in the coffee maker,' perfectly matching the subject-predicate-object relationship presented in the claim.
- qualifier_fidelity 0.60 fail — The time qualifier is unfaithful. The passage explicitly states 'It was in 1711 that the infusion idea in coffee making appeared in France,' so the claim's 'when' should be 1711, not null. The quote is accurate and supports the claim, but the missing temporal information fails to capture the passage's explicit dating of this event.
- groundedness 1.00 pass — The claim is directly stated in the passage: 'It was in 1711 that the infusion idea in coffee making appeared in France.' The subject, predicate, object, and timing all match exactly what is written.
- qualifier_fidelity 0.90 pass — The claim is highly faithful to the passage qualifiers. The viewpoint is correctly attributed to the author (no named source in the passage), stance is accurately 'asserts', sentiment is neutral, and the quote appears verbatim and supports the claim. The time qualifier (1711, valid_from: 1711, valid_to: null) correctly reflects the passage's temporal scope. Minor deduction (0.1): the context field is empty, which is appropriate since the passage provides no restrictive context qualifier, making this fully acceptable. All qualifiers are faithful.
