by the end of 1911, the coffee market stood well above thirteen cents
judge verdicts (2)
- groundedness 0.70 pass — The passage directly states 'By the end of 1911, the coffee market stood well above thirteen cents.' The claim accurately captures this information, though it slightly simplifies 'well above thirteen cents' to 'stood at price thirteen cents,' which is a minor rewording that represents the general assertion without distortion.
- qualifier_fidelity 0.90 pass — The claim is nearly faithful to the passage qualifiers. The viewpoint, stance, and sentiment are all appropriate - the author presents this as a factual assertion. The time qualifier correctly captures 'by the end of 1911' with valid_from of 1911-12-31 and null valid_to. The context is appropriately empty. However, there is a minor issue with the quote: the passage states 'stood well above thirteen cents' but the claim's predicate says 'stood at price' which slightly misrepresents the quote's meaning of being 'above' rather than 'at' that price point. The quote itself is verbatim and accurate, but the predicate object pairing could be more precise to reflect the superlative nature ('well above').
a rise of more than one hundred percent in two years
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Here was a rise of more than one hundred percent in two years' referring to the coffee market price by the end of 1911, which supports the timeframe of approximately 1909-1911.
- qualifier_fidelity 0.80 pass — The claim is largely faithful to the passage. The quote is verbatim and accurate. However, the 'sentiment' qualifier is questionable: the passage frames this price rise as part of a scheme by bankers and merchants to manipulate the market, presenting it in a somewhat critical or neutral analytical tone rather than a positive sentiment. The passage does not celebrate this rise; it contextualizes it as part of a 'valorization' scheme by 'the bankers' committee.' The time qualifiers are correct (two years, valid_from 1909, valid_to 1911). The stance 'asserts' is appropriate. The viewpoint 'author' is acceptable since the passage presents this as factual observation without attributing it to a specific named source. Context is appropriately empty as no specific sense restriction is needed.
more than sixty percent in six months
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Here was a rise of more than one hundred percent in two years, more than sixty percent in six months.' The quoted text explicitly confirms the coffee market rose more than sixty percent in six months.
- qualifier_fidelity 0.85 pass — The claim is largely faithful to the passage. The quote appears verbatim and accurately supports the rise in coffee prices. The time qualifier 'in six months' is faithful to the passage. However, there is a minor issue with sentiment: the passage frames this price rise within a critical investigation of market manipulation ('Evidently, valorization coffee in the hands of the bankers' committee had become a gilt-edged security. But how?'), suggesting skepticism rather than a purely positive sentiment. The sentiment should be 'neutral' or 'mixed' rather than 'positive' to reflect the passage's investigative tone questioning whether this was genuine market growth or artificial manipulation. All other qualifiers are accurate.
