  judge verdicts (2)

  • groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly says 'by certain optical devices they may be confined to a single plane, and light thus confined is called polarized,' which directly supports the subject-predicate-object relationship that polarized light is light confined to a single plane.
  • qualifier_fidelity 0.90 pass — The claim is nearly faithful to the passage. All qualifiers are appropriate: viewpoint is correctly attributed to 'author' (the passage presents this as general knowledge, not from a named source), stance is 'asserts' (the passage states this definitively), sentiment is neutral (no evaluative language), time qualifiers are properly null (no temporal scope given), and context correctly reflects 'by certain optical devices.' The quote is verbatim and supports the claim. Minor note: the claim's predicate 'is light confined to' slightly reorders the passage's phrasing 'light thus confined is called polarized,' but this is a reasonable paraphrase that maintains fidelity to the core meaning.
