    judge verdicts (2)
    • groundedness 1.00 pass — The claim is directly stated in the passage. Fraser explicitly attributed the retarding effect on peptic digestion to the tannic acid of tea, as shown in the quote provided.
    • qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint correctly attributes the statement to Fraser (named source), stance is appropriately 'asserts' for an attribution of causation, sentiment is neutral, time qualifiers are correctly null as the passage provides no temporal scope, context accurately specifies 'in tea', and the quote appears verbatim and directly supports the claim about tannic acid's retarding effect on digestion.

P. L. Simmonds (author)

  • _Paullinia sorbilis_, leaves of several species of holly contain tannic acid present (implied)
    assertsneutralsource: pg57340
    The nutritive and medicinal virtues of all these plants must certainly be attributed in a great degree to the presence of this chemical principle, and to the tannic acid which they also contain.
    judge verdicts (2)
    • groundedness 0.70 pass — The passage states that 'the nutritive and medicinal virtues of all these plants must certainly be attributed in a great degree to ... and to the tannic acid which they also contain,' directly supporting the claim that _Paullinia sorbilis_ and leaves of several holly species contain tannic acid. The wording is slightly rephrased but remains consistent with the source.
    • qualifier_fidelity 0.90 pass — All qualifiers are faithful except for a minor nuance in time qualification. The passage implies a timeless observation about the constituents of coffee and related plants, so 'present (implied)' is acceptable but could be more explicitly stated as 'timeless' or 'always'. Otherwise, viewpoint, stance, sentiment, context, and quote align perfectly with the passage.
