judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage, which states: 'Burns & Brown started in the coffee roasting business in 1853 in an old building at the corner of Washington and Chambers Streets.' All elements of the claim match the source text exactly.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage narrative voice, not a named source). The stance is correctly marked as 'asserts' - the passage presents this as factual. The sentiment is neutral, matching the passage's straightforward tone. The time is accurate: 1853 with valid_from matching the start date and valid_to as null (no end date specified). The context is appropriately empty since the passage does not restrict the claim to a particular sense or role. The quote appears verbatim in the passage and directly supports all elements of the claim.

- groundedness 1.00 pass — The claim is directly stated in the passage: 'Burns & Brown started in the coffee roasting business in 1853 in an old building at the corner of Washington and Chambers Streets for which they paid an annual rental of one thousand dollars.' The subject, predicate, and object are all explicitly mentioned with the same wording as the quote provided.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage presents this as factual history without attribution to a named source). The stance 'asserts' matches the passage's straightforward presentation. The sentiment is neutral, appropriate for a factual statement about rental costs. The time qualifier correctly identifies 1853 as when Burns & Brown started and paid this rental. The context is appropriately empty as the passage provides no specific sense restriction. The quote is verbatim from the passage and directly supports the claim.
Burns & Brown continued for two years
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage with the exact wording 'Burns & Brown continued for two years, when they failed.' The time period 1853-1855 is correctly derived from the start date of 1853 plus two years.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The quote is verbatim, viewpoint and stance are correct (the author asserts this), sentiment is neutral and appropriate, and the calculated dates (1853-1855) are consistent with the passage statement that Burns & Brown started in 1853 and continued for two years. Minor deduction: the time qualifier uses 'when': null with valid_from/valid_to, which is a reasonable interpretation where the passage provides a duration rather than a specific moment, though this represents a slightly different temporal representation than typical null usage.
