The char, as it goes in, has a temperature of from 170 to 180 degrees Fahrenheit
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The exact quote provided matches the text: 'The char, as it goes in, has a temperature of from 170 to 180 degrees Fahrenheit.' No rewording or outside knowledge is required.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly identified as 'author' (the passage presents this as a general statement of fact). The stance 'asserts' is appropriate. The sentiment 'neutral' matches the technical, descriptive tone. The time qualifiers are correctly set to null as no specific temporal scope is given. The context 'as it enters filter' accurately reflects the passage's specification that this temperature applies when 'the char, as it goes in.' The quote is verbatim and directly supports the claim.
the char, containing about twenty per cent of water, drops to the floor below
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'The bottom doors of the filter are then opened and the char, containing about twenty per cent of water, drops to the floor below.' This is a precise match to the source material without any added interpretation or outside knowledge.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage is a descriptive technical account with no named source). The stance is accurately 'asserts' - the passage presents this as factual description. The sentiment is neutral, matching the technical, objective tone. The time qualifiers are all null, which is correct since the passage provides no temporal information. The context 'from filter bottom doors' accurately reflects the passage's specification that 'The bottom doors of the filter are then opened and the char...drops to the floor below.' The quote is verbatim from the passage and directly supports the claim.
the char, containing about twenty per cent of water
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage with the exact phrase 'the char, containing about twenty per cent of water' when describing what drops to the floor below after the filter doors are opened.
- 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 describing the process). The stance 'asserts' accurately reflects how the passage presents this as factual information. The sentiment 'neutral' matches the technical, descriptive tone. Time qualifiers are appropriately null as the passage provides no temporal information. The context 'when dropped from filter' correctly captures the specific moment in the process described. The quote appears verbatim in the passage and directly supports the claim about water content in the char.
it passes through mechanical driers
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'the char, containing about twenty per cent of water, drops to the floor below. Here it passes through mechanical driers and is delivered comparatively free from moisture to the kilns.' The subject, predicate, and object are explicitly mentioned with no rewording needed.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage is a neutral technical description without named sources). The stance is correctly marked as 'asserts' - the passage states this as fact. Sentiment is neutral, matching the technical, objective tone. Time qualifiers are all null, which is correct since the passage provides no temporal information. Context is empty, which is appropriate as the passage does not restrict the claim to a specific sense or role. The quote 'it passes through mechanical driers' appears verbatim in the passage and accurately supports the claim.
delivered comparatively free from moisture to the kilns
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'is delivered comparatively free from moisture to the kilns.' The subject (char), predicate (is delivered to), and object (kilns) are explicitly mentioned with the exact context provided.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (no named source is specified in the passage). The stance is correctly marked as 'asserts' - the passage makes a straightforward declarative statement. The sentiment is appropriately neutral, matching the technical, factual tone of the passage. The time qualifiers are correctly null, as the passage provides no temporal information. The context 'comparatively free from moisture' is accurately extracted from the passage and appropriately restricts the claim to the state of the char at that specific point. The quote is verbatim from the passage: 'delivered comparatively free from moisture to the kilns' and directly supports the claim that char is delivered to kilns.
it is revivified, that is, the organic matter in the char which could not be removed by washing is converted into carbon by being heated to a cherry red in the absence of air
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The quoted sentence explicitly describes that char 'is revivified' through 'being heated to a cherry red in the absence of air,' which matches the subject-predicate-object relationship presented in the claim.
- 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 without attribution to a named source). The stance is appropriately 'asserts' - the passage states this as fact. Sentiment is neutral, matching the technical, objective tone. Time qualifiers are correctly null as the passage provides no temporal scope. Context is appropriately empty as the passage does not restrict the claim to a particular sense or period. The quote appears verbatim in the passage and directly supports the claim about char being revivified through heating.
the char to pass by gravity through the red-hot retorts of the kilns
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The final sentence explicitly states 'This is accomplished by allowing the char to pass by gravity through the red-hot retorts of the kilns,' which matches the subject, predicate, and object of the claim with the specified context of 'by gravity.'
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage describes the process without naming a specific source). The stance is appropriately 'asserts' as the passage states this as fact. Sentiment is neutral, matching the technical, descriptive tone. Time qualifiers are all null, which is correct as the passage provides no temporal information. Context accurately captures 'by gravity' from the passage. The quote 'the char to pass by gravity through the red-hot retorts of the kilns' appears verbatim in the passage and directly supports the claim.
the char passes gradually through the red-hot retorts, it becomes heated to 900 degrees Fahrenheit
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The text explicitly states 'As the char passes gradually through the red-hot retorts, it becomes heated to 900 degrees Fahrenheit,' which directly confirms that char is heated to a specific temperature (900°F) in the retorts.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage itself describes the process without naming a specific source). The stance is appropriately 'asserts' as the passage states the fact directly. The sentiment is neutral, matching the technical, descriptive tone of the passage. The time qualifiers are correctly null since no temporal scope is specified. The context is appropriately empty as the passage does not restrict the claim to a particular sense or period. The quote is verbatim and accurately supports the claim about char being heated to 900 degrees Fahrenheit in retorts.
the char becomes almost as good as new, or, as the term goes, revivified
judge verdicts (2)
- groundedness 1.00 pass — The passage directly states that char is revivified through the heating process in the kiln: 'As the char passes gradually through the red-hot retorts, it becomes heated to 900 degrees Fahrenheit and the organic matter it absorbed from the sugar liquor is changed into carbon. In this way the char becomes almost as good as new, or, as the term goes, revivified.' The claim accurately represents this directly stated relationship.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The viewpoint is correctly attributed to the author (the passage describes the process without naming a specific source). The stance 'asserts' and sentiment 'neutral' are appropriate. The time qualifiers are correctly set to null since the passage provides no temporal information. The context is appropriately empty as the passage does not restrict the claim to a particular sense or role. The quote is verbatim and supports the claim. The only minor consideration is that the claim's predicate 'revivified through heating in kiln' slightly simplifies the complex process described (the char passes through red-hot retorts within the kiln, not just 'in' the kiln generally), but this is a reasonable abstraction rather than an unfaithful qualifier.
liquor that has been filtered over the char at least twice
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly says 'liquor that has been filtered over the char at least twice,' which matches the subject (sugar liquor), predicate (is filtered over), and object (char) with the context of 'at least twice' all clearly supported.
- qualifier_fidelity 0.80 pass — The claim is largely faithful to the passage. The viewpoint, stance, sentiment, and time qualifiers are all appropriate. However, the context qualifier is imprecise: 'at least twice' is not a context that restricts the sense or role of the subject, but rather a quantifier/frequency modifier describing how many times the filtering occurs. The context field should be empty or null, as the passage does not restrict sugar liquor to a particular sense, role, or period. The quote is accurate and supports the claim.
