judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The opening sentence explicitly describes Hollingworth's investigation as 'at once the most comprehensive, carefully conducted, and scientifically accurate one yet performed,' which directly supports the claim's predicate and characterization.
- qualifier_fidelity 0.85 pass — The claim is largely faithful to the passage. However, the viewpoint qualifier should be 'author' (the passage itself makes this assessment), not attributed to a specific named source—this is correct. The stance and sentiment are accurately 'asserts' and 'positive.' The time qualifiers are correctly null as the passage provides no specific dates. The context is appropriately empty. The quote is verbatim from the passage and accurately supports the claim. Minor deduction: the claim slightly simplifies the original predicate by omitting 'Subsequent to these investigations was' framing, but this does not materially affect the fidelity of the core claim. All qualifiers are faithful.
