By 1777 there were 18,791,680 coffee trees in Martinique
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage with an exact quote: 'By 1777 there were 18,791,680 coffee trees in Martinique.' All elements of the claim (subject, predicate, object, time, and context) are precisely supported by this sentence.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (no named source in passage), stance is 'asserts' (presented as factual statement), sentiment is neutral, time is accurate ('By 1777' with valid_from 1777 and valid_to null), context correctly specifies 'in Martinique', and the quote appears verbatim in the passage supporting the claim.
- coffee trees are grown most generally from seeds selected from trees of known productivity and longevity seeds
Coffee trees are grown most generally from seeds selected from trees of known productivity and longevity
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The exact quote appears verbatim in the PROPAGATION section, asserting that coffee trees are grown most generally from seeds selected from trees of known productivity and longevity.
- 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 a general statement without attribution to a named source. The stance 'asserts' is appropriate as the passage makes a straightforward claim. The sentiment 'neutral' matches the factual, informational tone. The time qualifiers are correctly set to null as the passage provides no temporal scope. The context is appropriately empty as no specific sense or period restriction is given. The quote appears verbatim in the passage and directly supports the claim about coffee tree propagation.
The coffee trees are in bloom from September to December
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'The coffee trees are in bloom from September to December.' The subject, predicate, and object are all explicitly mentioned with no rewording or external knowledge required.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (passage does not cite a named source). The stance is accurately represented as assertion. The sentiment is neutral, matching the passage's factual tone. The time qualifiers correctly reflect the passage's stated blooming period of September to December with no other temporal restrictions given. The context is appropriately specified as Brazil's coffee belt, which matches the passage's opening reference to 'Brazil's coffee belt.' The quote is verbatim from the passage and directly supports the claim.
About 700 trees are usually planted to the acre
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'About 700 trees are usually planted to the acre.' The subject, predicate, and object all match the source text without any rewording or interpretation required.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage itself makes this statement without attribution to a named source). The stance is correctly marked as 'asserts' (the passage states this as fact). The sentiment is neutral, which matches the passage's straightforward presentation. The time qualifiers are correctly set to null, as the passage provides no temporal specificity for this general cultivation practice. The context is appropriately empty, as the passage discusses coffee trees in their general agricultural sense without restricting to a particular sense, role, or period. The quote is verbatim from the passage and directly supports the claim.
in 1888 there were 168,000,000 coffee trees in the country on 346,000 acres of land
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'in 1888 there were 168,000,000 coffee trees in the country on 346,000 acres of land.' The subject, predicate, object, time period, and context all match the quoted text exactly without any rewording or outside knowledge required.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The quote is verbatim and accurate. The time qualifier is correct (1888). The context correctly specifies Venezuela. The perspective viewpoint is labeled as 'author' rather than a named source, which is appropriate here since the passage presents this information without attribution to a specific named source. However, there is a minor issue: the passage states the figure 'in 1888' without explicitly framing it as the author's assertion or an estimate—it presents it as fact. The 'asserts' stance is reasonable and matches the passage's presentation. The sentiment of 'neutral' is appropriate. All qualifiers are faithful to the passage.
The trees are usually planted from two to two and a quarter meters apart
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'The trees are usually planted from two to two and a quarter meters apart.' This is a verbatim match with no rewording needed, making it fully grounded in 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 information without attributing it to a named source). The stance is appropriately 'asserts' as the passage states this as fact. The sentiment is neutral, matching the passage's objective tone. The time qualifiers are correctly null since the passage provides no specific temporal scope for this practice. The context is appropriately empty as the claim refers to coffee trees without qualification to a specific sense or period. The quote is verbatim from the passage and directly supports the claim.
Under cultivation are from 70,000,000 to 100,000,000 trees
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage with the exact quote provided: 'Under cultivation are from 70,000,000 to 100,000,000 trees.' This is a precise match requiring no rewording or interpretation.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (passage states facts without attribution to a named source). The stance is 'asserts' which matches the declarative presentation. The sentiment is neutral, appropriate for a factual statement. The time qualifiers are null, which is correct as the passage provides no temporal scope. The context is empty, which is appropriate as the passage discusses coffee trees generally without restricting to a specific sense or role. The quote appears verbatim in the passage and directly supports the claim.
The trees are usually in flower in February, March, and April
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'The trees are usually in flower in February, March, and April.' The subject, predicate, and object all match the source text without any rewording or addition of outside knowledge.
- 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 information without attributing it to a named source). The stance is 'asserts' which matches the passage's straightforward statement. The sentiment is neutral, appropriate for a factual claim about flowering times. The time qualifier correctly captures the temporal scope given ('in February, March, and April') with null values for valid_from and valid_to, which is appropriate since no broader temporal restriction is mentioned in the passage. The context 'Guatemala' is accurate as the passage explicitly discusses Guatemala's coffee industry. The quote is verbatim from the passage and directly supports the claim.
the trees were largely permitted to fall into a wild natural state
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The exact phrase 'the trees were largely permitted to fall into a wild natural state' appears verbatim in the first paragraph describing Haiti's coffee cultivation history.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (passage narrative voice). The stance is correctly marked as 'asserts' - the passage states this as fact. The sentiment is appropriately negative, reflecting the passage's framing of this as a problem retarding industry advancement. The time qualifiers are correctly null, as the passage provides no specific temporal scope for this state beyond the general historical context. The context is appropriately empty as the passage does not restrict this to a specific sense or role. The quote appears verbatim and directly supports the claim about coffee trees falling into wild natural state.
Trees flower in January and March, and in high altitudes as late as June or July
judge verdicts (4)
- groundedness 0.70 pass — The passage directly states 'Trees flower in January and March' with the noted caveat that at high altitudes flowering occurs as late as June or July. The claim accurately captures the stated flowering period for typical altitudes, though it omits the high-altitude exception mentioned in the passage.
- qualifier_fidelity 0.60 fail — The qualifier 'context' is unfaithful. The passage states trees flower in January and March, and separately notes that at high altitudes flowering occurs 'as late as June or July.' The claim restricts this to low altitudes, but the passage does not attribute the January-March timeframe specifically to low altitudes—it applies this general statement to all altitudes, then adds an exception for high altitudes. The context should be empty or should note 'general/all altitudes' rather than 'low altitudes.' Additionally, the quote is incomplete: the full relevant sentence is 'Trees flower in January and March, and in high altitudes as late as June or July,' which provides important temporal qualification that contradicts the claim's contextual restriction.
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Trees flower in January and March, and in high altitudes as late as June or July.' The subject (coffee trees), predicate (flower in), and object (January and March) are all explicitly supported by the text.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The quote is verbatim and accurately supports the claim. Viewpoint, stance, and sentiment are all appropriate. The time qualifier correctly reflects when the passage states trees flower. However, there is a minor issue: the claim presents the flowering time as simply "January and March" when the passage actually indicates this is the primary/general flowering time, with high altitudes flowering "as late as June or July." The context is appropriately empty since the passage does not restrict this to a specific sense. The quote provided is accurate but incomplete - it omits the important qualification about high altitudes. This incompleteness in the quote selection, while the claim itself remains accurate for the general case, represents a minor fidelity concern in terms of representing the full temporal scope the passage conveys.
in high altitudes as late as June or July
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Trees flower in January and March, and in high altitudes as late as June or July.' The subject, predicate, and object are all explicitly present with the qualifying context of high altitudes.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The viewpoint, stance, and sentiment are correctly identified as 'author', 'asserts', and 'neutral'. The context 'high altitudes' accurately reflects the passage's qualifier 'in high altitudes'. The quote is verbatim and supports the claim. However, there is a minor issue with the 'time' qualifier: the passage provides specific months (June or July), but the 'when' field should represent the temporal scope more clearly. The claim states 'when': 'June or July', which is acceptable, though ideally it should reflect that this is a seasonal occurrence rather than a single point in time. The valid_from and valid_to being null is appropriate since the passage provides no date range. Overall, the qualifiers are faithful to the passage.
the trees are planted about eight feet apart
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'the trees are planted about eight feet apart, an average of 680 trees to the acre.' This is an exact match with no rewording needed.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (implied narrator), the stance is properly asserted, sentiment is neutral as appropriate, time qualifiers are correctly null since no specific temporal scope is given for the planting distance practice, context is appropriately empty as no specific sense restriction applies, and the quote appears verbatim in the passage supporting the claim about spacing coffee trees eight feet apart.
On account of the size of the trees, only about four hundred can be planted to the acre
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The exact quote provided matches the text about Liberian coffee trees, clearly indicating that only about four hundred trees can be planted to the acre due to their size.
- qualifier_fidelity 0.90 pass — The claim is faithful to the passage qualifiers with one minor issue. The viewpoint is correctly attributed to the author (the passage makes this assertion in its text). The stance is correctly marked as 'asserts' (not disputed or questioned). The sentiment is neutral, matching the passage's factual tone. The time qualifiers are correctly set to null, as the passage provides no temporal scope for this statement. The context appropriately specifies 'Liberia' and references the causal factor (size of trees). The quote is verbatim and supports the claim. However, the context could be slightly more precise by specifying 'cultivated Liberian coffee' rather than just 'coffee trees,' since the passage specifies this constraint applies to 'Cultivated Liberian coffee, Coffea liberica' specifically. This is a minor refinement rather than a substantial error. Overall, the qualifier fidelity is high.
The trees bear for fifteen to twenty years
judge verdicts (4)
- groundedness 1.00 pass — The claim is directly stated in the passage. The exact sentence 'The trees bear for fifteen to twenty years' appears verbatim in the Bolivia section, with no rewording or interpretation needed.
- qualifier_fidelity 0.60 fail — The 'time' qualifier is incorrect. The 'when' field should be null since the passage does not establish when this bearing period occurs temporally, only how long it lasts. The passage states a duration (fifteen to twenty years), not a temporal scope with valid_from/valid_to dates. Additionally, 'context' should not be empty - it should specify that this refers to the lifespan/productive period of the trees, not a temporal context. The quote is accurate and the other qualifiers (viewpoint, stance, sentiment) are faithful to the passage.
- groundedness 1.00 pass — The claim is directly stated in the passage: 'The trees bear for fifteen to twenty years' appears verbatim in the Bolivia section, making this a fully supported claim 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 presents this as factual information without attribution to a named source). The stance is accurately marked as 'asserts' since the passage states this as a direct claim. Sentiment is appropriately neutral. The time qualifiers are correctly set to null since the passage provides no temporal scope. The context appropriately specifies 'productive lifespan in Bolivia,' which accurately reflects the passage's restriction of this information to the Bolivia section. The quote is verbatim from the passage and directly supports the claim.
- coffee trees number approximately 1,000,000 1916 ⟨in bearing⟩
altogether there were about 1,000,000 trees in bearing
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly says 'altogether there were about 1,000,000 trees in bearing' in a 1916 survey, matching the subject, predicate, object, time period, and context of the claim exactly.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (implied by the survey report). The stance 'asserts' appropriately matches the declarative nature of the claim. The sentiment is neutral, consistent with the factual reporting. The time is correctly set to 1916, matching the survey reference. The context 'in bearing' is accurately included from the passage. The quote appears verbatim and directly supports the claim about the number of coffee trees.
the trees can be successfully grown on the plains at sea-level as well as up to a height of 1,500 or 2,000 feet
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'the trees can be successfully grown on the plains at sea-level as well as up to a height of 1,500 or 2,000 feet.' The quote provided matches the text exactly, and the claim accurately captures what the passage asserts about coffee cultivation in Queensland.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage itself makes this assertion, not a named source). The stance is accurately characterized as 'asserts' since the passage presents this as a factual statement. The sentiment is neutral, matching the informative tone of the passage. The time qualifiers are appropriately set to null since the passage provides no specific temporal restriction. The context is empty as appropriate since the passage does not restrict this to a particular sense or period. The quote matches verbatim and directly supports the claim about where coffee trees can be grown in Queensland.
- coffee trees yield crop in about two years and a half from planting crop January to July or August of second year
Planted in January, they frequently blossom in December of the next year, or a month later, and yield a small crop in July or August; that is, in about two years and a half from the time of planting
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The exact quote provided matches the text verbatim: 'Planted in January, they frequently blossom in December of the next year, or a month later, and yield a small crop in July or August; that is, in about two years and a half from the time of planting.' The claim accurately captures what the passage asserts.
- qualifier_fidelity 0.85 pass — The claim is largely faithful to the passage. The quote is verbatim and accurately supports the predicate about yielding crop in ~2.5 years. Viewpoint, stance, and sentiment are all appropriate. However, there is one minor issue with the 'time' qualifier: the 'when' field specifies "January to July or August of second year" but the passage indicates the timeline spans from January planting to "December of the next year, or a month later" for blossoming, then yield "in July or August" - this means the actual timeframe could span into the second or even third calendar year depending on interpretation, not strictly "second year." The temporal description is slightly imprecise relative to what the passage states. Additionally, the context field is empty when it should note this refers to Australian arabica coffee trees specifically (in Queensland), though this is a minor omission since the subject already identifies "coffee trees."
- coffee trees obtained better returns when planted at elevations of from 1,000 to 3,000 feet above sea-level ⟨Hawaii⟩
it was not until the trees were planted at elevations of from 1,000 to 3,000 feet above sea-level that better returns were obtained
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The exact quote provided matches verbatim text stating that better returns were obtained when coffee trees were planted at elevations of 1,000 to 3,000 feet above sea-level in Hawaii, as opposed to the low levels near the sea.
- 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 accurately characterized as 'asserts' - the passage presents this as factual information. The sentiment 'positive' is appropriate given the context of 'better returns.' The time is correctly null as the passage provides no specific date. The context 'Hawaii' is accurate and reflects the passage's focus. The quote is verbatim from the passage and directly supports the claim about elevation and returns.
coffee trees flourish surprisingly well among the rocks
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'coffee trees flourish surprisingly well among the rocks' is quoted verbatim from the final sentence describing conditions in the Kona coffee district of Hawaii. No outside knowledge or over-generalization is required.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage states the observation without attribution to a named source). The stance 'asserts' is appropriate as the passage presents this as factual information. The sentiment 'positive' matches the favorable connotation conveyed by 'flourish surprisingly well.' The time qualifiers are correctly null, as the passage provides no temporal scope. The context 'Kona' is accurate, as the statement appears in the section describing the Kona coffee district. The quote is verbatim and directly supports the claim.
Coffee trees in Kona are planted principally in the open
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the opening sentence of the passage: 'Coffee trees in Kona are planted principally in the open, though sometimes they are shaded by the native kukui trees.' The subject, predicate, and object are all explicitly present in the text without requiring outside knowledge or over-generalization.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (as an informational statement rather than a named source). The stance is 'asserts' which matches the declarative nature of the passage. Sentiment is neutral, appropriate for factual description. Time qualifiers are null as the passage provides no specific temporal scope. Context is empty as appropriate since the passage makes no distinction about different senses or roles of coffee trees. The quote is verbatim from the passage and directly supports the claim.
sometimes they are shaded by the native _kukui_ trees
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The opening sentence explicitly states that coffee trees in Kona 'are planted principally in the open, though sometimes they are shaded by the native _kukui_ trees,' which matches the claim exactly.
- 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 'asserts' which matches the declarative nature of the statement. The sentiment is neutral, appropriate for a factual agricultural description. The time qualifiers are appropriately null since the passage provides no temporal specification. The context 'sometimes' accurately captures the passage's qualifier 'sometimes they are shaded by the native kukui trees.' The quote is verbatim from the passage and directly supports the claim.
In two years a small crop is gathered, yielding from five to twelve bags of cleaned coffee per acre
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'In two years a small crop is gathered, yielding from five to twelve bags of cleaned coffee per acre.' The subject, predicate, object, and timeframe all match the source text without any over-generalization or external knowledge required.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (passive statement in the passage). The stance is accurately 'asserts' as the passage makes a straightforward claim. The sentiment is neutral, matching the factual tone. The time qualifier correctly specifies 'two years' as stated in the passage. The 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 yield at two years of age.
At three years of age the trees produce from eight to twenty bags of cleaned coffee per acre
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'At three years of age the trees produce from eight to twenty bags of cleaned coffee per acre.' The subject, predicate, and object are all explicitly mentioned with no rewording or inference required.
- qualifier_fidelity 0.85 pass — The claim is largely faithful to the passage. The quote is verbatim and accurately supports the predicate. The viewpoint, stance, and sentiment are all appropriate. However, there is a minor qualifier issue: the passage specifies "cleaned coffee" in the quote, but the claim's object does not include this important specification. The "cleaned" qualifier is material to the claim's meaning and should be retained in the object or noted in context to fully capture the passage's precision. The time qualifier is appropriately captured as relative ("three years") with null absolute dates, which matches the passage's temporal framing.
from that time they are fully matured
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'At three years of age the trees produce from eight to twenty bags of cleaned coffee per acre, and from that time they are fully matured.' The passage explicitly indicates that coffee trees are fully mature at three years of age.
- qualifier_fidelity 0.90 pass — Qualifier fidelity is strong. Viewpoint is correctly attributed to 'author' (no named source in passage). Stance 'asserts' is appropriate. Sentiment 'neutral' matches the passage's objective tone. Time qualifier 'three years' is accurate. Context is appropriately empty as no specific sense restriction applies. Quote is verbatim and supports the claim. Minor deduction only because the claim uses 'fully mature at' while the passage states 'from that time they are fully matured'—technically the passage indicates maturity is achieved BY three years, not AT three years specifically, though this is a negligible semantic distinction.
the coffee trees numbered 8,000,000
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The exact phrase 'the coffee trees numbered 8,000,000' appears in the Ecuador section, and the temporal qualifier 'several years ago' matches the passage's statement 'Several years ago it was estimated that the coffee trees numbered 8,000,000.'
- qualifier_fidelity 0.90 pass — The claim is nearly faithful to the passage qualifiers. The viewpoint, stance, sentiment, time, and context all correctly reflect the source material. The quote is verbatim from the passage: 'the coffee trees numbered 8,000,000'. Minor note: the passage frames this as 'it was estimated that the coffee trees numbered 8,000,000,' which includes an attribution to an estimate rather than direct fact, but the claim's use of 'author' as viewpoint and 'asserts' as stance reasonably captures this, as the author is reporting the estimate. All qualifiers are appropriately faithful.
planted on 32,000 acres
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Several years ago it was estimated that the coffee trees numbered 8,000,000, planted on 32,000 acres.' The subject, predicate, and object are all explicitly present without requiring outside knowledge or over-generalization.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The quote 'planted on 32,000 acres' appears verbatim and supports the claim. Context ('in Ecuador'), stance ('asserts'), and sentiment ('neutral') are all correct. The time qualifier accurately reflects the passage's language 'Several years ago it was estimated that the coffee trees numbered 8,000,000, planted on 32,000 acres.' Minor note: The viewpoint is listed as 'author' which is appropriate since the passage itself (not a named source) provides this statement. All qualifiers are faithful to the passage.
Yet when they reach the destined shore, With pride the heroic gardener sees A living sap still in his trees
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The quoted lines explicitly describe the coffee trees reaching 'the destined shore' with 'a living sap still in his trees,' confirming their survival of the voyage. The author's positive sentiment is evident through the phrase 'heroic gardener' and the celebration of this achievement.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The quote accurately reflects the passage's depiction of the coffee trees surviving the voyage with "a living sap still in his trees." The sentiment is correctly marked as positive, matching the passage's tone of pride and heroic achievement. The viewpoint is appropriately marked as "author" since the passage is a poem narrating this story directly. However, there is a minor issue: the context field is empty, but the passage does provide context—these are coffee trees specifically being transported to Martinico as part of establishing coffee plantations. Including "transport to Martinico" or similar context would be more precise, though this is a minor omission that doesn't substantially undermine the claim's fidelity.
Companhia Guatapara, 1,550,000 trees
judge verdicts (4)
- groundedness 0.70 pass — The passage states 'Companhia Guatapara, 1,550,000 trees' in the context of large plantations in Sao Paulo. While the claim uses the general phrasing 'has trees' and 'coffee' rather than the specific number, it is directly supported by the passage with minor rewording of how the relationship is expressed.
- qualifier_fidelity 0.65 fail — The 'context' qualifier is unfaithful. The passage lists 'Companhia Guatapara, 1,550,000 trees' as one of the large plantations in Sao Paulo, but does not specify that these are coffee trees. The passage mentions 'coffee plantations' in general context, but the specific claim about Companhia Guatapara's trees should either include 'coffee' in the context field or the object should be 'trees' with context 'coffee plantation in Sao Paulo' to accurately reflect what the passage states. Additionally, the time qualifier should include a normalized 'when' value reflecting the passage's implicit contemporary timeframe (early 20th century, around 1918 based on the Colonel Francisco Schmidt reference), though passing null is defensible if treating this as undated information.
- groundedness 1.00 pass — The passage directly states that Companhia Guatapara is among large plantations in Sao Paulo and specifies it has 1,550,000 trees, which are coffee trees based on the context of coffee plantations.
- qualifier_fidelity 0.85 pass — The claim is largely faithful to the passage. The viewpoint, stance, and sentiment are all appropriate - the passage presents factual information without attribution to a specific named source, so 'author' as viewpoint is correct. The context 'large plantation in Sao Paulo' is accurate as Companhia Guatapara is listed among plantations with a million or more trees in Sao Paulo. The quote is verbatim from the passage. However, there is a minor issue: the passage does not specify a temporal scope for this data point, yet the claim uses null for 'when' which is appropriate. The only slight weakness is that the claim says 'has coffee trees' (present tense) when the passage lists historical data about plantations, though this is a common convention for such factual statements and the passage structure supports treating these as established facts about these entities.
had practically destroyed all the trees of the country
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The text explicitly states that Ceylon leaf disease 'had practically destroyed all the trees of the country' a few years after attacking plantations in 1869, and this destruction occurred in the context of Ceylon's coffee industry.
- qualifier_fidelity 0.85 pass — The claim is largely faithful to the passage. The quote is verbatim and accurately supports the claim. Viewpoint, stance, and sentiment are all appropriate. The context is correctly specified as Ceylon. However, the time qualifier has a minor issue: 'valid_from' should be null or omitted since the passage does not attribute the destruction to 1869 itself—rather, it states the disease 'attacked' in 1869 and 'a few years later' the destruction occurred. The 'valid_from' of 1869 conflates the attack date with the destruction date. The 'when' value of 'a few years later' is correct and faithful to the passage's temporal language.
The trees mature earlier than in some other countries
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage with the exact quote: 'The trees mature earlier than in some other countries.' This is a straightforward assertion about Queensland coffee trees that requires no rewording or interpretation.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to 'author' since the passage makes this assertion directly without attribution to a named source. The stance 'asserts' correctly reflects the declarative statement in the passage. The sentiment 'positive' is appropriate as earlier maturation is presented as an advantageous characteristic. The time qualifiers are correctly null since the passage provides no specific temporal scope for this claim. The context is appropriately empty as the passage does not restrict this statement to a particular sense or role. The quote is verbatim from the passage and directly supports the claim.
