judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'It melts at 235-7 deg. C. and sublimes completely at 178 deg. C., though the sublimation starts at 120 deg.' This directly supports that sublimation of caffeine starts at 120 degrees Celsius.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (passage presents this as direct factual information without attribution to a named source). The stance is appropriately 'asserts' as the passage states this as fact. The sentiment is neutral, matching the technical/scientific tone of the passage. Time qualifiers are correctly null as no temporal scope is specified. Context is appropriately empty as no contextual restriction applies. The quote appears verbatim in the passage and accurately supports the claim about sublimation starting at 120 degrees Celsius.
