of soft coal
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'The fire was about sixteen to eighteen inches below the cylinder and of soft coal.' The passage explicitly describes the fire as being made of soft coal.
- qualifier_fidelity 0.85 pass — The claim is largely faithful to the passage. The subject, predicate, and object are accurate (fire made of soft coal). The viewpoint is correctly 'author' since the passage uses first-person narration ('our medium', 'we had'). The stance 'asserts' and sentiment 'neutral' are appropriate. The time qualifiers (null values) are correct as the passage provides no specific dates. However, the quote 'of soft coal' is incomplete - the full relevant phrase from the passage is 'The fire was about sixteen to eighteen inches below the cylinder and of soft coal.' A more complete quote would better support the claim's context within the roasting apparatus description. The context is appropriately empty since the passage doesn't restrict this to a specific sense or role.
We still used soft coal
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The author explicitly states 'We still used soft coal, with the fire sixteen to eighteen inches under the cylinder,' confirming that soft coal was used as fuel in their roasting process.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author ('We still used soft coal' uses first-person perspective). The stance is appropriately 'asserts' as a straightforward statement of fact. The sentiment is neutral, matching the passage's matter-of-fact tone. The time qualifiers are correctly set to null as the passage provides no specific temporal scope. The context is appropriately empty as the passage does not restrict the claim to a particular sense or role. The quote appears verbatim in the passage and directly supports the claim that the roasting process used soft coal.
