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.
