First reliable date (1454)
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage under the 'Beverage' entry, which explicitly lists 'First reliable date (1454)' under the 'Origin' subsection. The passage directly supports this claim without requiring outside knowledge or over-generalization.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The quote appears verbatim and accurately reflects the passage's content about the beverage discovery date of 1454. The perspective, stance, and sentiment are all appropriate. However, there is a minor inconsistency: the 'when' field is set to null, but 'valid_from' is set to '1454'. For temporal consistency, if valid_from is specified as 1454, the 'when' field should typically align with this or clarify the temporal scope. The time qualifier structure is slightly awkward but not fundamentally unfaithful to the passage's presentation.
