Bone-char has the peculiar property of removing from the sugar liquor, in some unknown mechanical way, not only the soluble salts but the coloring matter as well
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The quoted sentence explicitly states that bone-char removes both soluble salts and coloring matter from sugar liquor, matching the subject, predicate, and object of the claim exactly.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. Viewpoint is correctly identified as 'author' since the passage presents this as general knowledge rather than attributing it to a named source. Stance 'asserts' is appropriate as the passage states this as fact. Sentiment 'neutral' matches the passage's objective, descriptive tone. Time qualifiers are correctly null as the passage provides no temporal scope. Context is empty as appropriate since no specific sense or role restriction applies. The quote is verbatim and directly supports the claim about bone-char's property of removing salts and coloring matter.
through which it drops into the retorts of the kiln
judge verdicts (2)
- groundedness 0.90 pass — The claim is directly supported by the passage. The text explicitly states that dried bone-char 'runs freely by gravity from the bottom of the drier into a second set of hoppers, through which it drops into the retorts of the kiln.' The claim accurately captures this process with only minor rewording of the original text.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (implicit narrator of the technical description). The stance is appropriately 'asserts' as the passage describes this process as fact. Sentiment is neutral, matching the objective, technical tone. Time qualifiers are all null, which is correct as the passage provides no temporal information. Context is empty, which is appropriate as bone-char has a single, consistent sense throughout. The quote 'through which it drops into the retorts of the kiln' appears verbatim in the passage and accurately supports the claim about bone-char dropping from second hoppers into retorts.
the bone-char is tested every twenty-four hours as a check upon the process of revivification in the kilns
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The exact quote provided matches verbatim: 'the bone-char is tested every twenty-four hours as a check upon the process of revivification in the kilns.' All elements—subject, predicate, object, timing, and context—are explicitly supported.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly identified as 'author' (the passage presents this information directly without attribution to a named source). The stance 'asserts' is appropriate as the passage states this as fact. The sentiment is neutral, matching the passage's objective, technical tone. The time qualifier 'every twenty-four hours' is directly supported by the passage. The context 'in kilns' correctly reflects the passage's specification of where the revivification process occurs. The quote is verbatim and directly supports the claim.
once a month the bone-char is completely analyzed to determine the deterioration that has taken place in it
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The exact phrase 'once a month the bone-char is completely analyzed to determine the deterioration that has taken place in it' appears verbatim, making this a fully supported assertion with no rewording necessary.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (implicit narrator describing laboratory procedures). The stance is properly marked as 'asserts' rather than 'disputes' or 'questions'. The sentiment is neutral, matching the objective, technical tone of the passage. The time qualifier 'once a month' matches exactly what the passage states. The context is appropriately empty since the passage does not restrict bone-char to a specific sense or role. The quote is verbatim from the passage and directly supports the claim.
beet-sugar factories in the United States do not use bone-char
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Contrary to the general practice in Europe, beet-sugar factories in the United States do not use bone-char.' This is an explicit assertion that matches the subject, predicate, and object of the claim exactly.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author who asserts this as fact. The stance of 'asserts' is appropriate as the passage states this as a direct claim, not a dispute or question. The sentiment is neutral, matching the passage's factual tone. The time qualifiers are correctly null, as the passage provides no specific temporal scope. The context 'United States' accurately reflects the geographical restriction stated in the passage. The quote is verbatim and directly supports the claim.
Contrary to the general practice in Europe
judge verdicts (2)
- groundedness 0.70 pass — The passage states 'Contrary to the general practice in Europe, beet-sugar factories in the United States do not use bone-char,' which directly implies that the general practice in Europe is to use bone-char. This supports the claim with minor logical rewording—the passage doesn't explicitly state 'European beet-sugar factories use bone-char' but establishes this through contrast.
- qualifier_fidelity 0.90 pass — Minor issue with quote selection: The quoted phrase 'Contrary to the general practice in Europe' supports the claim's meaning but doesn't directly state that European beet-sugar factories use bone-char. A more direct quote would be 'beet-sugar factories in the United States do not use bone-char' (which by implication of 'contrary to the general practice in Europe' indicates European ones do use it). However, the quote is accurate and does support the claim. All other qualifiers are faithful: viewpoint (author), stance (asserts), sentiment (neutral), time (null - passage gives no temporal scope), and context (Europe) are all correct.
hot air obtained from cooling the char in the cooling pipes below the retorts is drawn through the drier, coming in direct contact with the char
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The exact quote provided matches the passage text stating that 'hot air obtained from cooling the char in the cooling pipes below the retorts is drawn through the drier, coming in direct contact with the char,' confirming all elements of the subject-predicate-object relationship.
- 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 factual description without attribution to a named source.

Time qualifiers are correctly null as no temporal information is provided. Context is appropriately empty as the passage does not restrict the claim to a particular sense or role. The quote is verbatim from the passage and directly supports the claim about hot air being drawn through the drier in direct contact with the char.
Each kiln has a capacity of revivifying sixty thousand pounds of bone-char per day
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage's final sentence: 'Each kiln has a capacity of revivifying sixty thousand pounds of bone-char per day.' All elements—subject (kiln), predicate (capacity to revivify), object (bone-char), and context (per day)—are explicitly present with no rewording or generalization needed.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (passage presents this as factual description). The stance is appropriately 'asserts' as the passage states this as fact. The sentiment is neutral, matching the technical/descriptive tone. The time qualifiers are correctly null as no temporal scope is specified beyond the daily capacity mentioned in context. The context 'per day' accurately reflects the passage's specification. The quote is verbatim from the passage and directly supports the claim about kiln capacity.
