and to D.B. Fraser in 1899
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'David B. Fraser, of New York, began to market in the United States a central-heated gas-fuel machine with an inner wire-cloth cylinder to keep the coffee from dropping into the flame, developed under United States patents granted to Carl H. Duehring, of Hoboken, in 1897, and to D.B. Fraser in 1899.' The subject, predicate, and object are all explicitly supported.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage itself states the fact rather than attributing it to a named source). The stance is appropriately 'asserts' as the passage presents this as factual information. The sentiment is neutral, matching the passage's objective tone. The time qualifier correctly identifies 1899 as when D.B. Fraser was granted the patent, which matches the passage statement 'to D.B. Fraser in 1899'. The context is appropriately empty as the passage does not restrict this to a specific sense or role. The quote 'and to D.B. Fraser in 1899' appears verbatim in the passage and directly supports the claim.
