judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Marcus Mason & Co., established in 1873 at Worcester, Mass.' All elements (company name, establishment year, and location) are explicitly provided without any rewording or inference needed.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (not a named source). The stance of 'asserts' matches the passage's straightforward presentation. The sentiment is appropriately neutral. The time qualifier correctly shows 1873 as the establishment date with no end date specified. The context is empty as appropriate since no specific sense or role restriction applies. The quote appears verbatim in the passage and directly supports the claim about Marcus Mason & Co.'s establishment in Worcester, Mass.

assignor to Marcus Mason & Co., New York, is granted United States patents on a coffee pulper and a coffee drier
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The final entry states that Douglas Gordon, assignor to Marcus Mason & Co., New York, is granted United States patents on a coffee pulper and a coffee drier during 1904-05, which matches all elements of the claim including the company, patents, time period, and location.
- qualifier_fidelity 0.85 pass — The claim is largely faithful to the passage. Viewpoint, stance, sentiment, time, and context are all accurate. However, there is a minor issue with the quote: it does not appear verbatim in the passage. The passage states 'Douglas Gordon, assignor to Marcus Mason & Co., New York, is granted United States patents on a coffee pulper and a coffee drier.' The claim's quote omits 'Douglas Gordon' at the beginning, making it incomplete though still supportive of the claim. The predicate 'is assigned patents for' slightly simplifies the original 'is granted United States patents on,' though this is a minor semantic variance rather than a substantive qualifier issue.
