judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Finley Acker, of Philadelphia, was granted a United States patent on a percolator employing two cylinders, perforated on the sides, with a sheet of percolator paper placed between them to act as a filtering medium' in 1905. All elements (subject, predicate, object, and time) are explicitly supported.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (passage narrative). The stance is appropriately 'asserts' as a factual statement. The sentiment is neutral. The time is correctly set to 1905, matching the passage. The context is empty, which is appropriate as the passage does not restrict the claim to a specific sense or role. The quote appears verbatim in the passage and accurately supports the claim.
