Add water to the ash, in the platinum dish
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Add water to the ash, in the platinum dish, heat nearly to boiling' - the passage explicitly instructs to add water to the ash.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly set to 'author' as the passage presents instructional directives without attribution to a named source. The stance of 'asserts' is appropriate for the imperative instruction. The sentiment is neutral, matching the technical, factual nature of the procedural text. The time qualifiers are correctly null as the passage provides no temporal scope. The context is appropriately empty as there are no sense or role restrictions needed for this straightforward procedural claim. The quote 'Add water to the ash, in the platinum dish' appears verbatim in the passage and directly supports the claim that water is added to ash.
- water could be turned off into other channels when fruit began to ripen other channels when fruit began to ripen
the water could be turned off into other channels when the fruit began to ripen
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'These were so constructed that the water could be turned off into other channels when the fruit began to ripen.' The subject (water), predicate (could be turned off into other channels when fruit began to ripen), and object (other channels) are all explicitly mentioned with identical wording.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (not a named source). The stance is appropriately 'asserts' as the passage states this as fact. The sentiment is neutral, matching the passage's descriptive tone. The time qualifier correctly references the temporal condition 'when fruit began to ripen' without imposing absolute dates. The context is appropriately empty as the passage provides no restrictive sense or role. The quote appears verbatim in the passage and directly supports the claim about water management in Arab coffee plantations.
when a pumping percolator or a double glass filtration device is used, the water may be cold or boiling at the beginning
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly says 'When a pumping percolator or a double glass filtration device is used, the water may be cold or boiling at the beginning as the maker prefers,' which exactly 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 (not a named source). The stance is appropriately 'asserts' for a factual statement about procedure. The sentiment is neutral, matching the instructional tone. The time qualifiers are all null, which is correct as the passage provides no temporal scope. The context accurately reflects the restriction to 'pumping percolator or double glass filtration device' usage. The quote is verbatim from the passage and directly supports the claim about water temperature options.
the water as near the boiling point as possible, all during the process
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The first section explicitly says 'the water as near the boiling point as possible, all during the process' is essential to the success of making coffee, matching the subject-predicate-object relationship precisely.
- qualifier_fidelity 0.85 pass — The claim is mostly faithful to the passage. The quote is verbatim and supports the claim. However, the viewpoint qualifier is problematic: the passage explicitly attributes this statement to 'our experience' (the first-person plural voice describing the Hotel Astor method), not to an unnamed 'author.' While the claim captures the correct perspective from the passage, the viewpoint should reflect that this is from the Hotel Astor's experience/method rather than a generic authorial assertion. All other qualifiers (stance, sentiment, time, context) are appropriate and faithful to the passage.
boil one-third of it away what quantity soever it be, and it is fit for use
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The text explicitly states 'Take clean water, and boil one-third of it away what quantity soever it be, and it is fit for use,' which precisely matches the claim that water is fit for use after boiling one-third away.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (implied instructional voice). The stance is 'asserts' which matches the prescriptive tone. The sentiment is neutral, appropriate for a technical instruction. Time qualifiers are all null, which is correct as the passage provides no temporal scope. Context is empty, which is appropriate as no specific sense or role restriction applies. The quote appears verbatim in the passage and accurately supports the claim about water fitness after boiling one-third away.
The whole water to be used must be divided into two equal parts
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage's opening sentence: 'The whole water to be used must be divided into two equal parts.' The subject, predicate, and object are all explicitly present without any rewording or inference required.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The quote is verbatim and accurately supports the statement. However, there is a minor issue with the viewpoint qualifier: the passage attributes this instruction to 'Professor Donovan's suggestions' and the context of 'Webster and Parkes' published method, not to an unnamed 'author.' The claim should specify the source (Professor Donovan or Webster and Parkes) rather than using the generic 'author.' All other qualifiers—stance (asserts), sentiment (neutral), time (null), context (coffee preparation)—are faithful to the passage.
The water not only retains the valuable oil and other aromatic elements
judge verdicts (2)
- groundedness 0.70 pass — The claim is directly supported by the passage. The quoted text states that water 'retains the valuable oil and other aromatic elements,' which matches the predicate. The structure as a knowledge graph triple is slightly awkward (with 'oily matter' as object), but the core assertion about water retaining valuable oils and aromatic elements is explicitly stated in the passage.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. Viewpoint is correctly attributed to 'author' (the passage presents this as general advice without naming a specific source). Stance is correctly marked as 'asserts' - the passage states this as fact. Sentiment is correctly 'positive' - retaining valuable elements is presented favorably. Time qualifiers are correctly null as the passage provides no temporal scope. Context is appropriately empty as the passage discusses water in its general role without restricting to a specific sense. The quote is verbatim and directly supports the claim about water retaining oil and aromatic elements.
Let the water percolate over the grounds for five or ten minutes
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The exact phrase 'Let the water percolate over the grounds for five or ten minutes' appears verbatim in the PERCOLATED COFFEE section, fully supporting all elements of the claim including the subject, predicate, object, time duration, and context.
- qualifier_fidelity 0.85 pass — The claim is largely faithful to the passage. The quote is verbatim, the context correctly identifies 'percolated coffee', the time qualifier accurately reflects the passage's duration, and the sentiment is appropriately neutral. However, there is a minor issue with the viewpoint qualifier: the passage explicitly attributes this instruction to Charles W. Trigg ('Charles W. Trigg has contributed the following discussion'), not to 'author'. The viewpoint should be 'Charles W. Trigg' rather than 'author' to be fully faithful to the passage's attribution.
The water as it comes into contact with the ground coffee extracts the soluble material
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage with the exact quote provided: 'The water as it comes into contact with the ground coffee extracts the soluble material.' This is a verbatim extraction from the text with no added knowledge or over-generalization.
- 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 an explanatory description rather than attributing it to a named source). 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 all null, which is correct since the passage provides no temporal scope. The context 'upon contact with ground coffee' accurately reflects the passage's specification of when extraction occurs. The quote is verbatim from the passage and directly supports the claim about water extracting soluble material.
It is very soluble in water
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'It is very soluble in water, slightly soluble in alcohol, and only very slightly soluble in ether, chloroform or benzol.' The subject (trigonellin), predicate (is very soluble in), and object (water) are all explicitly mentioned without rewording needed.
- 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 information without attribution to a named source). The stance is 'asserts' which matches the passage's straightforward assertion. The sentiment is neutral, appropriate for a scientific description of a chemical property. The time qualifiers are all null, which is correct since the passage provides no temporal scope. The context is empty, which is appropriate as the passage does not restrict this solubility to a particular sense or role. The quote 'It is very soluble in water' appears verbatim in the passage and directly supports the claim.
The crystals were insoluble in water
judge verdicts (2)

The Arab drinks water before taking coffee
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'The Arab drinks water before taking coffee, but never after it.' This sentence explicitly asserts the subject, predicate, and object without requiring any outside knowledge or interpretation.
- 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 knowledge, not attributed to a named source). The stance 'asserts' is appropriate as the passage states this as fact. The sentiment is neutral, matching the passage's factual tone. The time qualifier correctly reflects the temporal relationship ('before taking coffee') as stated in the passage. The context is empty, which is appropriate as the passage makes no contextual restrictions. The quote is verbatim from the passage and directly supports the claim.
but never after it
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'The Arab drinks water before taking coffee, but never after it.' This is explicitly asserted and further supported by the anecdote about the traveler being recognized as a foreigner for asking for water after coffee.
- qualifier_fidelity 0.85 pass — The claim is largely faithful to the passage. Viewpoint, stance, sentiment, and time qualifiers are all accurate. The quote 'but never after it' appears verbatim and supports the claim. However, there is a minor issue with the context qualifier: it is empty, but the passage provides a cultural context by attributing this practice to 'the Arab' and explaining the reasoning (not spoiling the taste of coffee). While this is not a critical fidelity issue, the context could more precisely reflect that this describes Arab coffee-drinking customs/culture. The empty context is acceptable given the passage doesn't restrict it to a specific technical sense, but noting the cultural context would be more complete.
Maronita infused two ounces of powder in three litres of water
judge verdicts (2)
- groundedness 0.70 pass — The passage states that 'Maronita infused two ounces of powder in three litres of water,' which directly supports the claim. The only minor issue is that the passage says 'powder' without explicitly naming it as 'coffee powder,' though the context makes clear this is about coffee preparation methods. The core claim is supported with minor rewording of 'powder' to 'coffee powder.'
- qualifier_fidelity 0.85 pass — The claim is largely faithful. The quote is verbatim and supports the predicate. Viewpoint, stance, sentiment, and time qualifiers are correct. However, the context field should not be empty - the passage specifies 'powder' (coffee powder by inference from context), and the claim's predicate explicitly states 'coffee powder,' which introduces terminology not literally in the passage. The context should clarify this is about the preparation method or leave the predicate as 'powder' to strictly match the passage's language. Minor deduction for this slight inference beyond the text.
All of these compounds, with the possible exception of the proteins, are easily soluble in both hot and cold water.
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the opening sentence of the passage. The passage explicitly asserts that compounds in coffee are easily soluble in both hot and cold water, with the noted exception of proteins, which is correctly captured in the claim's context field.
- 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 the author's assertion). The stance is accurately marked as 'asserts' - the passage states this as a fact. The sentiment is neutral, matching the objective, technical tone. The time qualifiers are all null, which is correct as the passage provides no temporal scope. The context accurately reflects the passage's qualification about proteins being a possible exception. The quote is verbatim and directly supports the claim.
