    judge verdicts (2)
    • groundedness 1.00 pass — The passage directly states that 'increased action of the heart, trembling, headache, &c., are effects of the caffeine,' providing clear support for the claim without any need for rewording or external knowledge.
    • qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage: - Viewpoint: correctly attributes the statement to the author (Professor Lehmann). - Stance: accurately reflects the assertive tone of the passage. - Sentiment: neutral, matching the factual presentation without bias. - Time: no temporal qualifiers needed as the passage is timeless in its general observation. - Context: empty is appropriate because the passage does not restrict the claim to a specific sense or role beyond what is already clear from the sentence about caffeine's effects. - Quote: the exact phrasing "increased action of the heart, trembling, headache, &c., are effects of the caffeine." appears verbatim in the passage, fully supporting the claim.
