- complete extraction is effected with clear solution ⟨when filter medium has proper fineness and water flows at correct rate⟩
complete extraction is effected with the production of a clear solution
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage, which explicitly states 'complete extraction is effected with the production of a clear solution' in the context of proper filter medium fineness and correct water flow rate. This is a verbatim match to the passage text.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage presents this as objective instruction without naming a specific source). The stance 'asserts' matches the passage's confident instructional tone. The sentiment 'positive' is appropriate given the passage frames this as producing 'a desirable drink.' The time qualifiers are correctly null as the passage provides no temporal scope. The context accurately reflects the passage's conditional framing: 'if the filter medium be of the proper fineness, the water flows through at the correct rate of speed, and complete extraction is effected.' The quote is verbatim from the passage and directly supports the claim.
- contrivances operating on filtration principle have proven successful in causing water to pass slowly through coffee without channeling complete extraction
have proven quite successful in causing all of the water to go slowly through the coffee without channeling, thus accomplishing practically complete extraction
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The exact quote provided matches the passage verbatim: 'have proven quite successful in causing all of the water to go slowly through the coffee without channeling, thus accomplishing practically complete extraction.' The subject, predicate, and object are all explicitly stated in the source material.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (implicit narrator of the technical passage). The stance 'asserts' matches the declarative framing. The sentiment 'positive' is appropriate given 'quite successful' conveys approval. The time qualifiers are correctly null as the passage provides no temporal specification. The context is appropriately empty as the passage does not restrict the claim to a particular sense or role. The quote is verbatim from the passage and directly supports the claim.
