judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'By the 1980s instant coffee and canned coffee had become fairly popular.' The subject, predicate, time period, and context all match the source text without requiring outside knowledge or over-generalization.
- qualifier_fidelity 0.90 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (narrator), stance is asserts, sentiment is positive ("fairly popular"), time span 1980-1989 correctly represents "by the 1980s", and the quote appears verbatim and supports the claim. Minor note: context is empty, which is appropriate since the passage provides no restricting context for canned coffee. The claim accurately reflects the passage's statement.
