judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Steele & Price, Chicago, are the first to introduce all-paper cans (made of strawboard) for coffee' in 1881. All elements match exactly without any rewording or outside knowledge required.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage states this as fact, not attributed to a named source). The stance 'asserts' is appropriate. The sentiment is neutral, matching the passage's neutral tone. The time qualifiers (when, valid_from, valid_to all 1881) match the passage exactly. The context 'Chicago, for coffee' is accurate and faithful to the passage. The quote is verbatim and supports the claim.
