The muscles are caused to contract more vigorously
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'The muscles are caused to contract more vigorously, increasing their working power without there being any secondary reaction leading to a diminished capacity for work.' The subject, predicate, and object match the source text exactly.
- qualifier_fidelity 0.90 pass — The claim is highly faithful to the passage. Viewpoint, stance, sentiment, time, and quote are all accurate. The context qualifier is appropriately empty since the passage does not restrict the claim to a specific sense or period. Minor deduction (0.1) because the passage attributes this to coffee's action through its pharmacological properties rather than presenting it as a direct assertion by a named author, though 'author' as viewpoint is acceptable for scientific exposition. All qualifiers appropriately match the passage's presentation.
increases their functional activity
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The opening sentence explicitly states that coffee 'increases their functional activity' in reference to muscles, matching the claim's predicate and object exactly.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The quote is accurate and the perspective qualifiers (viewpoint: author, stance: asserts, sentiment: positive) appropriately reflect the passage's medical assertion. The temporal qualifiers (null values) are correctly applied since the passage provides no specific timeframe. However, minor context specification could be improved: the passage specifically refers to 'strong black coffee' rather than just 'coffee', so the context field could be slightly more precise by noting 'strong black coffee' as the specific form discussed, though this is a minor omission rather than a material error.
