Rios, which had started the year at fourteen and one-half to sixteen and one-quarter cents
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly says 'Rios, which had started the year at fourteen and one-half to sixteen and one-quarter cents,' confirming that Rios coffee started 1880 at this price range.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly identified as 'author' since the passage presents this as an authorial statement with no named source attribution. The stance 'asserts' and sentiment 'neutral' are appropriate. The time qualifier correctly specifies 1880 with valid_from as '1880-01' (January) matching 'started the year'. The context is appropriately empty as the passage provides no additional contextual restrictions. The quote is verbatim from the passage and directly supports the claim about Rios prices at the start of 1880.
twelve and three-quarters cents in December, 1880
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Rios, which had started the year at fourteen and one-half to sixteen and one-quarter cents, were down to twelve and three-quarters cents in December, 1880.' The subject, predicate, object, and temporal reference all match the passage exactly.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The viewpoint, stance, sentiment, and time qualifiers are all correct. The quote is accurately extracted from the passage verbatim. One minor note: the quote should ideally include more context showing it refers to Rios prices (e.g., 'Rios...were down to twelve and three-quarters cents in December, 1880'), but the partial quote as provided does appear verbatim in the passage and the claim's qualifiers correctly tie it to Rios. The context field is appropriately empty as the passage does not restrict this to a specific sense or role.
had dropped nine and one-half cents when the break in the market culminated in June, 1881
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The text explicitly states 'had dropped nine and one-half cents when the break in the market culminated in June, 1881,' confirming that Rios coffee prices fell to nine and one-half cents in June 1881.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The quote appears verbatim and supports the claim. The time qualifier (June, 1881) is accurate and properly normalized. The perspective, stance, and sentiment are appropriate for an authorial assertion. However, there is a minor ambiguity in the quote: the passage says 'had dropped nine and one-half cents' which technically means a drop OF nine and one-half cents (from a higher price), whereas the claim's predicate 'had dropped to' could be interpreted as having dropped TO that price level. The passage is slightly ambiguous on this point, but contextually (given prior prices mentioned), this interpretation is reasonable. The context qualifier is appropriately empty as no restrictive sense or role is specified in the passage.
