judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage, which explicitly states: 'the polariscope has been devised for the purpose of measuring the rotation of the plane of polarization.' This is a verbatim match with no rewording needed.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly identified as 'author' since the passage presents this as a general statement without attribution to a named source. The stance is correctly 'asserts' as the passage makes a straightforward factual claim. Sentiment is neutral, matching the passage's objective tone. Time qualifiers are correctly null as the passage provides no temporal scope. Context is appropriately empty as the passage discusses polariscope in its general scientific sense without restricting to a specific role or period. The quote appears verbatim in the passage and directly supports the claim.
- polariscope is designed so that a standard weight of pure sugar dissolved in standard water rotates polarized light to one hundred degrees on the scale polarized light ⟨measurement of pure sugar concentration⟩
The polariscope is made and set so that a standard weight of pure sugar (C₁₂H₂₂O₁₁), dissolved in a standard quantity of pure water, and placed in a tube of given length, will rotate the ray of polarized light in passing through, to a point on the scale marked one hundred degrees
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The quoted text explicitly states that the polariscope is made and set so that a standard weight of pure sugar dissolved in standard water rotates polarized light to a point marked one hundred degrees on the scale, which matches the claim's subject-predicate-object formulation exactly.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (no named source in passage). The stance 'asserts' appropriately reflects the declarative framing. Sentiment is neutral as the passage presents technical specifications factually. Time qualifiers are correctly null as the passage provides no temporal scope. Context appropriately identifies this as measurement of sugar concentration. The quote is verbatim and directly supports the claim. No deductions warranted.
inserted in the polariscope between the eye of the operator and a strong artificial light
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly states that the tube 'is then inserted in the polariscope between the eye of the operator and a strong artificial light,' which directly supports the subject-predicate-object relationship claimed.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to 'author' (the passage is a general descriptive text without attribution to a named source). The stance 'asserts' matches the passage's straightforward declarative statement. The sentiment 'neutral' is appropriate for this technical description. The time qualifiers are correctly null as no temporal scope is specified. The context is empty as appropriate since no special sense or role restriction is indicated. The quote is verbatim from the passage and directly supports the claim about the tube being inserted in the polariscope.
