judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly says that carbonic acid gas is 'obtained from the lime-kilns, as the result of the decomposition of limestone and the combustion of the fuel used for burning it,' which matches the subject-predicate-object relationship exactly.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage is written in expository/informational style without attribution to a named source). The stance is properly 'asserts' - the passage states this as fact. Sentiment is neutral, matching the technical, matter-of-fact tone. The time qualifiers are correctly null as the passage provides no temporal scope. The context accurately reflects the passage's explanation that the gas results from limestone decomposition and fuel combustion in lime-kilns. The quote is verbatim and directly supports the claim about the origin of carbonic acid gas.
