progressive grocers stimulate interest in their coffees by serving, on special demonstration days, small cups of freshly brewed coffee
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The exact quote provided matches the text: 'progressive grocers stimulate interest in their coffees by serving, on special demonstration days, small cups of freshly brewed coffee.' All elements—subject, predicate, object, context, and sentiment—are fully supported by the passage 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 (the passage presents this as the author's observation, not attributed to a named source). Stance is properly marked as 'asserts' since the passage states this as fact. Sentiment is appropriately positive, reflecting the passage's framing of this as a 'progressive' practice that 'stimulate[s] interest.' Time is correctly null as the passage provides no specific temporal information. Context accurately captures 'on special demonstration days' as stated in the passage. The quote is verbatim and directly supports the claim.
- progressive grocer yields from roasting eighty-eight pounds roasted coffee per one hundred pounds green
he was able to get eighty-eight pounds of roasted coffee out of one hundred pounds of green coffee
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The text explicitly states that 'One progressive grocer found that he was able to get eighty-eight pounds of roasted coffee out of one hundred pounds of green coffee,' which exactly matches the subject, predicate, and object of the claim.
- qualifier_fidelity 0.85 pass — The claim is mostly faithful to the passage. The quote is accurate and verbatim. However, the viewpoint qualifier contains a minor issue: the passage does not identify the 'author' of this specific claim—it attributes the finding to 'One progressive grocer' who 'found' this result. The claim should use 'progressive grocer' as the viewpoint source rather than 'author', since the passage explicitly names the source of this statement. All other qualifiers (stance, sentiment, time, context) are appropriately faithful to the passage.
he could buy green coffee at a closer price than roasted
judge verdicts (2)
- groundedness 0.70 pass — The claim is essentially supported by the passage. The passage states the grocer 'could buy green coffee at a closer price than roasted,' which directly supports that green coffee can be bought at a lower price. The phrasing is slightly different (comparing green to roasted rather than explicitly comparing grocer to wholesaler prices), but the core assertion about the price advantage of green coffee is clearly stated.
- qualifier_fidelity 0.75 pass — The quote is slightly inaccurate. The passage states 'he could buy green coffee at a closer price than roasted' but this is comparing green coffee to roasted coffee prices, not to what the wholesaler could buy at. The claim's predicate says 'can buy at lower price than wholesaler' which is a reasonable inference from context (the grocer's advantage over wholesalers), but the quote provided doesn't explicitly state this wholesaler comparison—that comparison appears in the preceding sentence about the eighty-eight vs eighty-four pound yields. The viewpoint, stance, sentiment, time, and context qualifiers are all appropriate and faithful to the passage.

judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The text explicitly states that the progressive grocer 'could...buy green coffee at a closer price than roasted' and 'it cost him less for labor, fuel, overhead, and similar items, than it did the wholesale roaster to turn out a roast.' The claim accurately reflects this stated fact.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (who reports on the grocer's findings); the stance is 'asserts' which matches the passage's factual presentation; the sentiment is positive, reflecting the passage's favorable framing of the grocer's cost advantages; time is null as appropriate since no specific date is given for this example; context is empty as none is required; and the quote appears verbatim in the passage and directly supports the claim.
