Two of the boilers exploded
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Two of the boilers exploded' toward the end of 1886, making it impossible to operate during 1887-88. All elements of the claim are explicitly supported without requiring outside knowledge or over-generalization.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage presents this as historical fact without attribution to a named source). The stance is accurately 'asserts' - the passage states this as fact. The sentiment is appropriately 'negative' given the characterization as 'disaster'. The time qualifiers correctly specify 'toward the end of 1886' with valid_from and valid_to both as 1886, matching the temporal scope in the passage. The context is appropriately empty as the passage does not restrict this to a particular sense or role. The quote 'Two of the boilers exploded' appears verbatim in the passage and directly supports the claim about the boiler explosions.
