poured into a tube with glass ends, which is then inserted in the polariscope
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly says the clarified and filtered solution is 'poured into a tube with glass ends, which is then inserted in the polariscope,' matching the subject-predicate-object relationship exactly.
- qualifier_fidelity 0.90 pass — The claim's qualifiers are largely faithful to the passage. Viewpoint, stance, sentiment, and time are all appropriate. The quote is verbatim and supports the claim. Minor deduction: the context field is empty, but the passage does provide context—this occurs specifically during sugar testing using a polariscope. The context should reflect "in sugar testing" or "in polariscope measurement" rather than being left empty, as the passage clearly restricts this action to a specific procedural context.
- solution is diverted to separate tanks when density reaches threshold tanks when density lowered to about thirty-five per cent of solid matter
When its density has been lowered to about thirty-five per cent of solid matter, it is diverted to other tanks
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The exact quote provided matches the text: 'When its density has been lowered to about thirty-five per cent of solid matter, it is diverted to other tanks.' This is fully supported without any rewording or outside knowledge required.
- qualifier_fidelity 0.85 pass — The claim is largely faithful. The quote is verbatim and accurate. Qualifiers are appropriate: viewpoint is correctly "author" (the passage describes the process without attributing it to a named source), stance is "asserts" (matching the passage's declarative tone), sentiment is neutral (matching the technical, matter-of-fact presentation), and time qualifier correctly reflects the passage's conditional threshold. One minor issue: the claim says "separate tanks" but should say "other tanks" to match the exact language in the passage, though this is a semantic quibble since both convey the same meaning. Context is appropriately empty as the passage does not restrict meaning to a specific sense or role.
- solution is allowed to run to waste when sugar content falls below threshold waste when sugar content falls below three-tenths of one per cent
as soon as the sugar content falls below three-tenths of one per cent the solution is allowed to run to waste
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The final sentence explicitly confirms that 'as soon as the sugar content falls below three-tenths of one per cent the solution is allowed to run to waste,' which matches the claim's subject, predicate, object, and threshold condition exactly.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (implicit through third-person technical narration). The stance is appropriately 'asserts' as the passage states this as fact. The sentiment is neutral, matching the passage's objective tone. The temporal qualifier correctly identifies the condition 'when sugar content falls below three-tenths of one per cent' with no specified date range (valid_from and valid_to are null, as appropriate). The context is empty, which is correct as the passage provides no restricted sense or role specification. The quote is verbatim from the passage and directly supports the claim about the solution being allowed to run to waste based on sugar content threshold.
the latter remain in solution
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly says 'the latter remain in solution' referring to impurities that are excluded by sugar crystals during crystallization.
- 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 general technical explanation, not attributed to a named source). The stance is appropriately 'asserts' as the passage states this as fact. Sentiment is neutral, matching the passage's objective technical tone. Time qualifiers are all null, which is correct since the passage provides no temporal scope. Context is empty, which is appropriate as no specific context restriction is needed. The quote 'the latter remain in solution' appears verbatim in the passage and accurately supports the claim about impurities remaining in solution during the sugar boiling process.
which gradually becomes more and more dilute
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The text explicitly states that when hot water is turned into the filter, the sugar liquor 'gradually becomes more and more dilute,' which precisely matches the claim about sugar content becoming more dilute during washing.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage is written in third-person descriptive style). The stance 'asserts' accurately reflects the passage's straightforward descriptive tone. The sentiment is appropriately neutral for this technical description. The time qualifiers are correctly set to null since the passage provides no specific temporal scope. The context is appropriately empty as no restrictive sense or role is specified in the passage. The quote 'which gradually becomes more and more dilute' appears verbatim in the passage and directly supports the claim about the solution becoming progressively more dilute during the hot water washing process.
finely powdered lime is constantly added to the solution at a uniform and slow rate
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The exact phrase 'finely powdered lime is constantly added to the solution at a uniform and slow rate' appears verbatim in the Steffen Process section, fully supporting the subject-predicate-object relationship.
- 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 description). The stance is appropriately 'asserts' (not disputed or questioned). The sentiment is neutral, matching the technical, matter-of-fact tone of the passage. The time qualifiers are all null, which is correct since the passage provides no temporal scope. The context 'in the Steffen process' accurately reflects the passage's restriction of this claim to that specific process. The quote is verbatim from the passage and directly supports the claim.
