coal and coke burning roasters, the cylinders are heated by a fire underneath
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the opening sentence: 'In all types of coal and coke burning roasters, the cylinders are heated by a fire underneath.' This explicitly confirms that coal roasters have their cylinders heated by fire.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. All qualifiers are appropriate: viewpoint as 'author' is correct (the passage presents this as factual description), stance as 'asserts' matches the declarative nature, sentiment is neutral, and time qualifiers are correctly null since no temporal scope is given. The quote is verbatim and supports the claim. Context is appropriately empty as no specific sense or role restriction applies. Minor deduction: the quote could have been more complete to better represent 'in all types' of coal and coke roasters, but the selected quote is still accurate and representative.
