- groundedness 1.00 pass — The claim is directly stated in the passage: 'The "great coffee boom" forces the price of Rio 7's from seven and a half to twenty-two and a quarter cents, the subsequent panic reducing the price to nine cents.' The quote provided matches the source text exactly.
- qualifier_fidelity 0.85 pass — The claim is largely faithful to the passage. Viewpoint, stance, and sentiment are all appropriate. The quote is verbatim and supports the claim. However, there is a minor issue with the time qualifier: the passage states the price reduction to nine cents occurred during the 'great coffee boom' period (1886-88), but it specifically describes this as happening after the 'subsequent panic.' The temporal scope of 1886-88 encompasses the entire boom period, but the reduction itself is presented as a consequence event following the panic, which technically narrows the timing. The context qualifier accurately reflects the 'subsequent panic' framing from the passage. Overall, the claim faithfully represents the passage despite this minor temporal ambiguity.
