in Amsterdam and Hamburg, in 1887
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'the opening of coffee exchanges in Havre in 1882, in Amsterdam and Hamburg, in 1887' confirms that coffee exchanges opened in Amsterdam and Hamburg in 1887.
- qualifier_fidelity 0.95 pass — All qualifiers are faithful to the passage. The viewpoint 'author' is appropriate since the passage is presented as an authoritative statement without attribution to a named source. Stance 'asserts' correctly reflects the factual presentation. Sentiment is appropriately neutral. Time qualifiers (when: 1887, valid_from: 1887, valid_to: null) match the passage exactly. Context is correctly empty as the passage provides no specific sense restriction. The quote 'in Amsterdam and Hamburg, in 1887' appears verbatim and directly supports the claim. Minor deduction only for the slight redundancy between 'when' and 'valid_from' fields both being 1887, though this is a schema choice rather than a fidelity issue.
Five years later, coffee exchanges were opened in Amsterdam and Hamburg
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Five years later, coffee exchanges were opened in Amsterdam and Hamburg' (five years after Havre's 1882 exchange = 1887). The subject, predicate, and object are all explicitly supported without requiring outside knowledge or over-generalization.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage narrative voice). The stance is properly 'asserts' - a straightforward factual claim. Sentiment is neutral, matching the passage's neutral tone. The time qualifier correctly interprets 'five years later' (from 1882, the founding of Havre's exchange) as 1887, with valid_from set to 1887 and valid_to as null (the passage provides no end date). The context is appropriately empty as the passage makes no sense-specific restrictions. The quote is verbatim and directly supports the claim.
