It attained considerable popularity among housewives
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly states that Thomas R. Wood's 1849 spherical coffee roaster 'attained considerable popularity among housewives who preferred to do their own roasting,' which exactly matches the subject, predicate, and object of the claim.
- qualifier_fidelity 0.90 pass — The claim is nearly faithful to the passage. All qualifiers are correct: viewpoint is properly attributed to the author (the passage presents this as factual narrative), stance is 'asserts', sentiment is positive ('considerable popularity'), and the quote is verbatim. The time qualifier has valid_from='1849' which matches the patent date mentioned in the passage. Minor deduction only because the context field is empty when it could specify 'for use on kitchen stoves' as stated in the passage, though this is not strictly required since the passage does not restrict the claim to a specific sense or role in a way that would create confusion with other meanings.
In 1849 also, Thomas R. Wood, of Cincinnati, was granted a United States patent on a spherical coffee roaster

- groundedness 1.00 pass — The claim is directly stated in the passage: 'In 1849 also, Thomas R. Wood, of Cincinnati, was granted a United States patent on a spherical coffee roaster for use on kitchen stoves.' All elements (subject, predicate, object, and time) are explicitly supported by the text.
- qualifier_fidelity 0.90 pass — The claim is nearly faithful to the passage. All qualifiers are correct: viewpoint (author assertion), stance (asserts), sentiment (neutral), context (empty), and quote matches verbatim. However, there is a minor issue with the time qualifier: the passage states the patent was granted "in 1849" but provides additional context that it was "for use on kitchen stoves" and was popular "among housewives who preferred to do their own roasting." The "when" date of 1849 is correct, but the claim could be more complete by noting the specific use context mentioned in the passage. This is a very minor omission in context rather than an outright error in the time field itself. The claim accurately represents the passage's attribution and temporal scope.
