  judge verdicts (2)

  • groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly lists 'roasting by coal, coke, gas, and electricity' as fuel sources used in coffee roasting, which directly supports the subject-predicate-object relationship presented in the claim.
  • qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (implied by the instructional/informational text structure). The stance is appropriately 'asserts' as the passage presents this as factual information without dispute. The sentiment is neutral, matching the passage's objective tone. Time qualifiers are correctly null as no temporal scope is specified. Context is appropriately empty as the passage does not restrict the claim to a particular sense. The quote 'roasting by coal, coke, gas, and electricity' appears verbatim in the passage and directly supports the claim about fuel sources used in coffee roasting.
