    • groundedness 1.00 pass — The claim is directly stated in the passage: 'Sucrose contains twelve atoms of carbon, twenty-two atoms of hydrogen and eleven atoms of oxygen.' This is an exact match with the source text.
    • qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage presents this as factual content without naming a specific source). The stance is correctly marked as 'asserts' since the passage states this as fact. The sentiment is neutral, which matches the objective, scientific tone. Time qualifiers are appropriately null since the passage provides no temporal scope. Context is empty as appropriate since no specific sense or role restriction applies.

  • substance charred and burned until free of carbon carbon ⟨ash preparation procedure⟩

    judge verdicts (2)
    • groundedness 1.00 pass — The claim is directly stated in the passage under section 7 (_Ash--Official_). The exact phrase 'Char a quantity of the substance... and burn until free of carbon' is quoted verbatim from the instructions, making this a fully supported and grounded claim.
    • qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly identified as 'author' (the passage is instructional/procedural without attributing the statement to a named source). The stance 'asserts' is appropriate for a procedural instruction. The sentiment 'neutral' matches the technical, matter-of-fact tone. The time qualifiers are correctly null since the passage provides no temporal scope. The context 'ash preparation procedure' accurately reflects the section heading '7. _Ash--Official_' and the procedural framework. The quote is verbatim and directly supports the claim about charring and burning the substance until free of carbon.
