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.
