when Rio No. 7 is quoted at 17.10
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'By this scale one can determine that when Rio No. 7 is quoted at 17.10...' The specific price quotation of 17.10 for Rio No. 7 is explicitly mentioned with no rewording or generalization needed.
- 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 informational content without naming a specific source). The stance is properly marked as 'asserts' - the passage straightforwardly states the quotation. Sentiment is neutral, matching the factual tone. Time qualifiers are all null, which is correct since the passage provides no temporal information. Context accurately reflects 'price in pound and cents basis' as stated in the passage ('quotations are on the pound and cents basis'). The quote appears verbatim and directly supports the claim about Rio No. 7's quotation price.
By April 1890, the average import price per pound of Rio No. 7 in this country was nineteen cents
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'By April 1890, the average import price per pound of Rio No. 7 in this country was nineteen cents.' All details—the product (Rio No. 7), the price (nineteen cents per pound), the time (April 1890), and the location (the United States, referred to as 'this country')—are explicitly provided.
- qualifier_fidelity 0.90 pass — Qualifier fidelity is excellent. The viewpoint should be 'passage' rather than 'author' since the claim is a direct factual statement from the passage without attribution to a specific named source. All other qualifiers are faithful: stance is correctly 'asserts', sentiment is appropriately 'neutral', time is accurate with 'April 1890', context correctly specifies 'in the United States' (matching 'in this country'), and the quote is verbatim and supports the claim. Deduct 0.1 for the viewpoint term choice, though the substantive content is accurate.
by October of that year the price of Rio No. 7 in New York had fallen to about seven cents
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage, which explicitly states: 'By October of that year the price of Rio No. 7 in New York had fallen to about seven cents.' All elements (subject, predicate, object, time, and context) are accurately reflected from the source text without over-generalization.
- qualifier_fidelity 0.85 pass — The claim is largely faithful to the passage. The quote is verbatim and accurate. Viewpoint, stance, and sentiment are all appropriate. Context is correctly specified. However, there is a minor temporal issue: the claim's "when" field states "October 1896-97" which is awkward phrasing. The passage says "in 1896-97, when the new trees came into bearing" and then specifies "By October of that year the price...had fallen." The "when" should be normalized to "October 1897" (the October within the 1896-97 period) rather than the ambiguous "October 1896-97". The valid_from date of "1896-10" is also imprecise given the passage's framing. These are minor but represent slight unfaithfulness to the temporal scope as stated in the passage.
in 1903, it hung around five cents
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage, which explicitly states 'in 1903, it hung around five cents' when referring to the price of Rio No. 7 in New York. The subject, predicate, object, and time specification all match the text without requiring outside knowledge or over-generalization.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. Viewpoint is correctly attributed to the author (implicit narrator). Stance is appropriately marked as 'asserts' - the passage straightforwardly reports the price decline. Sentiment 'negative' accurately reflects the passage's framing of the price decline as part of 'Sao Paulo's folly' and 'discontent.' Time is correctly specified as 1903 with valid_from matching. Context appropriately identifies the New York market as stated in the passage. Quote appears verbatim ('in 1903, it hung around five cents') and directly supports the claim about Rio No. 7's price.
