The passage explicitly describes this negotiation method for coffee transactions.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (who describes the practice), the stance is appropriately 'asserts' (the passage presents this as factual description), sentiment is neutral (descriptive rather than evaluative), time qualifiers are correctly null (no specific date given), context is appropriately empty (the practice is described generally without restriction to a particular sense or period), and the quote appears verbatim and directly supports the claim.

judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage with the exact quote provided. The passage explicitly says 'Thus the buyer and the seller when entering upon a transaction know exactly what the difference will be between the standard No. 7 and the coffee that can be delivered.' No rewording or interpretation beyond what is written is required.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (implicit narrator of the passage). The stance of 'asserts' is appropriate as the passage presents this as fact. The sentiment is neutral, matching the passage's objective tone. Time qualifiers are correctly null, as the passage provides no specific temporal scope for this rule. Context accurately reflects 'when entering upon a transaction' as stated. The quote is verbatim and directly supports the claim about buyer and seller knowledge of grade differences.
