  judge verdicts (4)

  • groundedness 1.00 pass — The claim is directly stated in the passage. The exact sentence 'The trees bear for fifteen to twenty years' appears verbatim in the Bolivia section, with no rewording or interpretation needed.
  • qualifier_fidelity 0.60 fail — The 'time' qualifier is incorrect. The 'when' field should be null since the passage does not establish when this bearing period occurs temporally, only how long it lasts. The passage states a duration (fifteen to twenty years), not a temporal scope with valid_from/valid_to dates. Additionally, 'context' should not be empty - it should specify that this refers to the lifespan/productive period of the trees, not a temporal context. The quote is accurate and the other qualifiers (viewpoint, stance, sentiment) are faithful to the passage.

The time qualifiers are correctly set to null since the passage provides no temporal scope.

The quote is verbatim from the passage and directly supports the claim.
