Book's (1665)
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. Under 'Grinding machines' > 'Household', 'Book's (1665)' is explicitly listed as a household grinding machine from 1665, exactly as stated in the claim.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is appropriately 'author' as the passage is an index without attributed sources. The stance 'asserts' correctly reflects the straightforward listing. The sentiment is neutral as appropriate for a reference index. The time qualifiers (when: 1665, valid_from: 1665, valid_to: null) accurately match the passage's specification '(1665)'. The context 'household' is correct as Book's machine is listed under the 'Household' section of grinding machines. The quote 'Book's (1665)' appears verbatim in the passage and supports the claim that this is a household grinding machine from 1665.
