judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the opening sentence of the passage: 'bone-char, bone-coal or bone-black, as it is variously called, is made from the bones of animals.' This matches the subject, predicate, and object exactly as presented in the claim.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to 'author' as the passage presents this as general knowledge rather than attributing it to a named source. The stance 'asserts' is appropriate as the passage states the fact directly. Sentiment is neutral, matching the informational tone. Time qualifiers are correctly null as the passage provides no temporal scope. Context is appropriately empty as no specific sense or role restriction applies. The quote is verbatim from the passage and directly supports the claim.
