  • groundedness 0.70 pass — The passage states that the low rate of typhoid fever contraction 'has often been attributed to drinking of coffee instead of water, the action of the coffee being partly due to the bactericidal effect of the caffeol and partly to the boiling of the water before infusion.' The claim accurately captures that boiling water before infusion is presented as contributing to preventing typhoid fever, though the passage attributes this more indirectly through the coffee-drinking practice rather than as a standalone measure.
  • qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The viewpoint, stance, sentiment, time, and context qualifiers are all appropriate. The quote is verbatim and supports the claim. One minor issue: the passage attributes this maintenance of low typhoid rates to general practice ('has often been attributed'), not specifically to the author as a personal assertion, though the passage does present this as factual information. The viewpoint 'author' is acceptable as the author is reporting this medical understanding, though 'source' or leaving it unattributed might be more precise. Overall, qualifier fidelity is strong.
