The coffee tree bears fruit, leaf, and blossom at the same time
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage as a caption: 'The coffee tree bears fruit, leaf, and blossom at the same time' (page 16). The subject, predicate, and object all match the source text exactly without rewording or interpretation.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The quote appears verbatim and accurately supports the claim. The viewpoint is correctly attributed to 'author' (the passage presents this as general information in an illustration caption, not attributing it to a named source). The stance is correctly marked as 'asserts' - the passage states this as a fact without dispute or qualification. The sentiment is appropriately neutral. The time qualifiers are correctly null since the passage provides no temporal scope. The context is appropriately empty as the passage does not restrict this to a particular sense or role of coffee tree.
Coffee tree in bearing, Lamoa, P.I.
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The caption 'Coffee tree in bearing, Lamoa, P.I.' explicitly states that a coffee tree in bearing (producing fruit) is located in Lamoa, P.I., which matches the subject, predicate, and object of the claim without requiring outside knowledge or over-generalization.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The quote appears verbatim as a figure caption. The viewpoint is correctly attributed to the author (the passage presents this as documentation rather than attribution to a named source). The stance is appropriately 'asserts' and sentiment is neutral, matching the factual, documentary nature of the caption. The context correctly identifies 'P.I.' (Philippine Islands) as specified in the passage. No temporal qualifiers are claimed, which is appropriate since the passage provides no date information. The claim accurately reflects what the passage states.
several crops are produced in one season
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'several crops are produced in one season, depending on the conditions of heat and moisture that prevail in the particular season.' The subject (coffee tree), predicate (produce multiple crops in one season), and object (coffee crops) are all explicitly supported by this sentence.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage itself asserts this fact). The stance is appropriately 'asserts' as the passage states this as a factual claim without dispute. The sentiment is neutral, matching the passage's descriptive tone. The time qualifier is correctly null since the passage provides no specific temporal scope for this phenomenon. The context is appropriately empty as the passage does not restrict this claim to a particular sense or role. The quote 'several crops are produced in one season' appears verbatim in the passage and directly supports the claim.
- coffee tree bear simultaneously on same branchlet ripe fruits, green fruits, open flowers, flower buds ⟨lowland plantations⟩
ripe fruits, green fruits, open flowers, and flower buds are to be found at the same time on the same branchlet
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The text explicitly states that in lowland plantations with perennial rain, 'ripe fruits, green fruits, open flowers, and flower buds are to be found at the same time on the same branchlet,' which precisely matches the subject-predicate-object structure of the claim.
- qualifier_fidelity 0.90 pass — The claim is faithful to the passage with one minor issue. Viewpoint: 'author' is appropriate as the passage does not attribute this observation to a named source. Stance: 'asserts' is correct. Sentiment: 'neutral' is correct. Time: null is appropriate as no specific time is mentioned for this observation. Context: 'lowland plantations' is correct and properly restricts the claim. Quote: the quoted text appears verbatim and supports the claim. The only minor deduction: the passage states these elements are found 'not mixed together, but in the order indicated,' which adds a qualification about their arrangement that the claim does not capture, though this does not fundamentally undermine the claim's accuracy.
the coffee tree yields from one to twelve pounds a year, but of course this varies with the individual tree and also with the region
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage's opening sentence: 'the coffee tree yields from one to twelve pounds a year.' The quote provided matches the text exactly, including the acknowledgment that this varies by individual tree and region.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (implied by 'We have said'). The stance is appropriately 'asserts' for a declarative statement. Sentiment is neutral, matching the factual tone. Time is correctly null as no specific temporal scope is given. Context accurately reflects the passage's explicit statement that yield 'varies with the individual tree and also with the region.' The quote is verbatim and directly supports the claim.
In some countries the whole year's yield is less than 200 pounds per acre
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'In some countries the whole year's yield is less than 200 pounds per acre.' The subject, predicate, object, and contextual qualifier are all explicitly present 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 (the passage presents this as general information). The stance is appropriately 'asserts' rather than disputes or questions. The sentiment is neutral, matching the factual tone of the passage. The time qualifiers are correctly null, as no specific temporal restriction is given. The context 'in some countries' is faithful to the passage's explicit qualifier. The quote appears verbatim and directly supports the claim about coffee tree yields per acre.
there is on record a patch in Brazil which yields about seventeen pounds to the tree
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'there is on record a patch in Brazil which yields about seventeen pounds to the tree.' The passage explicitly supports both the subject (coffee tree), predicate (yields per tree in Brazil), and object (about seventeen pounds) without any 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 a factual statement from the text itself). The stance 'asserts' is appropriate as the passage states this as recorded fact. The sentiment is neutral, matching the passage's neutral presentation. The time qualifiers are correctly null, as the passage provides no temporal scope. The context 'a recorded patch in Brazil' faithfully reflects the passage's specification 'on record a patch in Brazil.' The quote is verbatim and directly supports the claim about the seventeen-pound yield per tree.
Trees raised from seed begin to blossom in about three years
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly and explicitly stated in the passage: 'Trees raised from seed begin to blossom in about three years.' The wording in the claim faithfully represents the source material without addition or over-generalization.
- qualifier_fidelity 0.80 pass — The claim is mostly faithful to the passage. The quote is accurate and the predicate, object, viewpoint, stance, and sentiment are all correct. However, there is a minor issue with the time qualifier: the 'valid_from' and 'valid_to' normalized dates should be null or not specified since the passage does not provide a range but rather an approximate timeframe ('about three years'). The normalized dates of exactly 3 and 3 are overly precise for an approximation expressed as 'about three years.' The time qualifier 'when' is correctly set to 'about three years,' but the normalized date boundaries should reflect the approximate nature rather than suggesting exact values.
a good crop can not be expected of them for the first five or six years
judge verdicts (4)
- groundedness 0.70 pass — The claim is directly stated in the passage: 'a good crop can not be expected of them for the first five or six years.' This logically implies that good crops can be produced after this period. The phrasing is slightly reworded from the original (negation reversed to affirmative), but the meaning is clearly supported.
- qualifier_fidelity 0.50 fail — Multiple unfaithful qualifiers: (1) STANCE: The claim states 'disputes' but the passage makes a straightforward factual assertion without disputing anything—this should be null or 'states'. (2) QUOTE MISUSE: The quoted text says a good crop 'can not be expected of them for the first five or six years,' meaning the crop comes AFTER this period, but the claim's predicate 'can produce good crop after' combined with 'object: first five or six years' is ambiguous and could be misinterpreted. The claim should clarify that good crops are expected only after the first five to six years have passed. (3) VIEWPOINT: While 'author' is acceptable here since the passage presents this as general knowledge rather than attributing it to a named source, the stance error is critical.
- groundedness 1.00 pass — The claim is directly stated in the passage: 'a good crop can not be expected of them for the first five or six years.' The subject (coffee tree), predicate (produces good crop only after), and object (five or six years) are all explicitly supported by the quoted text.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The viewpoint, stance, sentiment, and context are all appropriate. The quote is verbatim and accurately supports the claim. However, there is a minor issue with the time qualifier: the 'when' field states 'first five or six years', which is technically accurate to the passage text, but the predicate 'produces good crop only after' and the valid_from/valid_to values (5-6) make the temporal framing slightly ambiguous. The passage clearly means a good crop cannot be expected 'for the first five or six years' (i.e., before 5-6 years have passed), so the claim correctly captures that trees begin producing good crops after 5-6 years. The qualifier is faithful overall despite minor potential confusion in how the temporal boundaries are expressed.
Their usefulness, save in exceptional cases, is ended in about thirty years
judge verdicts (4)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Their usefulness, save in exceptional cases, is ended in about thirty years.' The subject, predicate, and object are all explicitly present with the same qualifier ('save in exceptional cases') and timeframe ('about thirty years').
- qualifier_fidelity 0.65 fail — The 'time' qualifier is unfaithful. The passage states usefulness 'is ended in about thirty years' (a temporal duration/lifespan, not a specific point in time), but the claim's time object incorrectly represents this as 'when: about thirty years' with valid_from and valid_to both set to '30'. This conflates the duration of the tree's usefulness with a temporal anchor. The time qualifier should either be null (since the passage gives no calendar date) or should clarify that '30 years' refers to the lifespan duration, not a temporal point. The viewpoint, stance, sentiment, context, and quote are all faithful to the passage.
- groundedness 1.00 pass — The claim is directly stated in the passage with the exact quote provided: 'Their usefulness, save in exceptional cases, is ended in about thirty years.' All elements including the subject, predicate, object, and the contextual qualifier 'save in exceptional cases' are explicitly present.
- 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 'asserts' which matches the declarative statement in the passage. The sentiment is neutral, appropriate for factual information. The time qualifiers are null as the passage provides no temporal context. The context 'save in exceptional cases' is accurately extracted from the passage and reflects the qualifier present in the original statement. The quote is verbatim and fully supports the claim.
The coffee tree can be propagated in a way other than by seeds. The upright branches can be used as slips
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The text explicitly states 'The coffee tree can be propagated in a way other than by seeds. The upright branches can be used as slips, which, after taking root, will produce seed-bearing laterals.'
- 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 general knowledge without attribution to a named source. The stance 'asserts' accurately reflects the declarative manner in which the passage states this fact. The sentiment is neutral, matching the passage's objective tone. The time qualifiers are appropriately null since the passage provides no temporal scope. The context is empty, which is correct as the passage does not restrict this claim to a particular sense or role of the coffee tree. The quote is verbatim from the passage and directly supports the claim about propagation via upright branches as slips.
The coffee tree, like every other living thing, has specific diseases and enemies, the most common of which are certain fungoid diseases
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The opening sentence explicitly states that 'The coffee tree, like every other living thing, has specific diseases and enemies, the most common of which are certain fungoid diseases,' which fully supports the subject-predicate-object relationship presented.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (not named source). The stance of 'asserts' matches the passage's declarative framing. The sentiment is neutral as befits a factual botanical description. The time qualifiers are appropriately null since the passage provides no temporal scope. The context is empty, which is appropriate as the passage does not restrict the claim to a specific sense or period. The quote is verbatim and directly supports the claim.
it is grown in well-defined tropical limits
judge verdicts (4)
- groundedness 0.70 pass — The passage directly states that the coffee tree 'is grown in well-defined tropical limits' and defines the 'coffee belt of the world' as lying between the tropic of cancer and the tropic of capricorn. The claim uses slight rewording ('coffee belt' instead of 'well-defined tropical limits') but accurately captures the relationship stated in the passage.
- qualifier_fidelity 0.60 fail — The quote is unfaithful: the exact statement in the passage is 'it is grown in well-defined tropical limits,' which does not explicitly mention the 'coffee belt' object in the claim. While the passage does state 'The coffee belt of the world lies between the tropic of cancer and the tropic of capricorn,' the quoted text does not directly support the specific claim that the coffee tree 'is grown in [the] coffee belt.' The quote should be either 'The coffee belt of the world lies between the tropic of cancer and the tropic of capricorn' or a passage that explicitly connects the tree's growth to the belt, or the object should be changed to 'well-defined tropical limits' to match the actual quote provided.
- groundedness 1.00 pass — The claim is directly stated in the opening sentence of the passage: 'A study of the geographical distribution of the coffee tree shows that it is grown in well-defined tropical limits.' The wording matches the passage 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 a general statement about geographical distribution without attributing it to a named source). The stance is 'asserts' which matches the passage's declarative presentation. The sentiment is neutral, appropriate for the factual, descriptive tone. The time qualifiers are all null, which is correct since the passage provides no specific temporal scope for this claim. The context is empty, which is appropriate as the passage does not restrict this to a particular sense of coffee tree. The quote appears verbatim in the passage and directly supports the claim.
The natural habitat of the coffee tree (all species) is tropical Africa
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the opening sentence of the passage: 'The natural habitat of the coffee tree (all species) is tropical Africa.' 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 (the passage presents this as factual information without attributing it to a named source). The stance is 'asserts' which matches the declarative nature of the statement. The sentiment is neutral, appropriate for a factual botanical claim. The time qualifiers are all null, which is correct since the passage provides no temporal scope for this natural habitat characteristic. The context is empty, which is appropriate as the passage does not restrict this to a particular sense or role. The quote is verbatim from the passage and directly supports the claim.
the trees and fruit generally can not withstand frost
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage, which explicitly states 'the trees and fruit generally can not withstand frost.' This is a precise match to the source text without any rewording or interpretation needed.
- 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 information rather than attributing it to a named source. The stance 'asserts' is appropriate as the passage states this as fact. The sentiment 'neutral' matches the passage's objective tone. The time qualifiers are correctly null as the passage provides no specific temporal scope for this general characteristic. The context is appropriately empty as the passage does not restrict this to a particular sense or role. The quote is verbatim from the passage and directly supports the claim.
mean annual temperature is about 70 deg. F.
judge verdicts (2)
- groundedness 1.00 pass — The passage directly states that coffee trees 'are restricted to regions where the mean annual temperature is about 70 deg. F.' This is a direct quotation from the source material with no added interpretation or outside knowledge required.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to 'author' (the passage presents factual information without naming a specific source). The stance 'asserts' matches the passage's definitive tone. The sentiment is neutral, appropriate for a factual claim about temperature requirements. The time qualifiers are correctly set to null as the passage provides no temporal scope. The context is appropriately empty as the passage discusses the coffee tree's general requirements without restricting to a specific sense or role. The quote 'mean annual temperature is about 70 deg. F.' appears verbatim in the passage and directly supports the claim about temperature requirements.
it has been successfully cultivated between latitudes 28 deg. north and 38 deg. south
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'it has been successfully cultivated between latitudes 28 deg. north and 38 deg. south.' The subject (coffee tree), predicate (has been cultivated between latitudes), and object (28 deg. north and 38 deg. south) are all 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 (no named source is given in the passage). The stance 'asserts' appropriately reflects the passage's declarative statement. The sentiment is neutral, matching the factual tone. The time qualifiers are correctly null since the passage provides no specific temporal scope for this cultivation range. The context is appropriately empty as no specialized sense or role is specified. The quote is verbatim from the passage and directly supports the claim.
the coffee tree requires an abundance of water, about seventy inches of rainfall annually
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'the coffee tree requires an abundance of water, about seventy inches of rainfall annually.' The subject, predicate, and object all match the source text without modification or over-generalization.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (implied passage authority). The stance is accurately 'asserts' - a straightforward claim without dispute. The sentiment is neutral, appropriate for a factual statement about requirements. The time qualifiers are correctly null since the passage provides no temporal scope. The context is appropriately empty as the passage makes no contextual restrictions. The quote is verbatim from the RAINFALL section and directly supports the claim about the seventy inches annual rainfall requirement.
the coffee tree takes potash, nitrogen, and phosphoric acid from the soil
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Because the coffee tree takes potash, nitrogen, and phosphoric acid from the soil, the scheme of fertilizing is to restore these elements.' The subject, predicate, and object are explicitly presented without requiring outside knowledge or 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 informational content without attributing it to a named source). The stance is 'asserts' which matches the passage's straightforward presentation. The sentiment is neutral, appropriate for this factual statement. Time qualifiers are null, consistent with the passage providing no temporal restriction. Context is empty, which is appropriate as the passage does not restrict this to a particular sense or period. The quote appears verbatim and directly supports the claim.
As the coffee tree grows older, it requires a larger supply of fertilizer
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage with an exact quote provided: 'As the coffee tree grows older, it requires a larger supply of fertilizer.' This sentence appears verbatim at the end of the passage and fully supports 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 makes a general statement without attribution to a named source). The stance is appropriately marked as 'asserts' - the passage makes a straightforward claim without disputing or questioning. The sentiment is neutral, matching the factual, technical tone of the passage. The time qualifier correctly uses 'as it grows older' without specifying absolute dates (valid_from and valid_to are null as appropriate). The context is empty, which is correct since the passage does not restrict the claim to a particular sense or role - it discusses the coffee tree in its general agricultural context. The quote is verbatim from the passage and directly supports the claim.
coffee trees sometimes grow as high as forty feet
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'If left to their own devices, coffee trees sometimes grow as high as forty feet.' The subject, predicate, and object match the passage exactly without requiring outside knowledge or over-generalization.
- qualifier_fidelity 0.95 pass — The claim is faithful to the passage across all qualifiers. The viewpoint is correctly attributed to 'author' as the passage presents this as general horticultural knowledge rather than attributing it to a named source. The stance 'asserts' correctly reflects the passage's presentation. The sentiment is neutral, matching the passage's objective tone. Time qualifiers are all null, which is correct as the passage provides no temporal scope. The context 'on larger plantations' accurately reflects the opening phrase 'On the larger plantations.' The quote is verbatim and directly supports the claim about unpruned growth reaching forty feet. Minor note: The claim could be slightly more precise by incorporating 'sometimes' from the quote to reflect the conditional nature, but this is a very minor consideration and does not affect the overall fidelity.
- coffee tree produce fruit with scanty yield when strength absorbed by wood ⟨on larger plantations when left unpruned⟩
the strength being absorbed by the wood, with a consequent scanty production of fruit
judge verdicts (2)
- groundedness 0.90 pass — The claim is directly supported by the passage. The text explicitly states that when coffee trees are left unpruned and grow very high, 'the strength being absorbed by the wood, with a consequent scanty production of fruit.' The causal relationship between wood absorption of strength and scanty fruit production is clearly articulated in the source material.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. Viewpoint is correctly attributed to 'author' (the passage presents this as factual information without attribution to a named source). Stance 'asserts' is appropriate as the passage states this as fact, not disputed. Sentiment 'negative' correctly reflects the passage's framing of scanty production as 'undesirable.' Time qualifiers are correctly null as the passage provides no temporal restriction. Context appropriately specifies 'on larger plantations when left unpruned' which matches the passage's opening statement. The quote is verbatim and directly supports the claim about the relationship between wood strength absorption and scanty fruit production.
the trees on the more modern plantations are pruned down to heights ranging from six to twelve feet
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The exact quote provided matches the passage text verbatim, confirming that on modern plantations, coffee trees are pruned down to heights ranging from six to twelve feet.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to 'author' (the passage presents this as factual information without naming a specific source). The stance 'asserts' is appropriate as the passage makes a declarative statement. The sentiment 'neutral' matches the informative tone. The time qualifiers are correctly set to null as the passage provides no specific temporal scope. The context 'on more modern plantations' accurately reflects the passage's restriction of this claim to that specific setting. The quote is verbatim and directly supports the claim.
the tree is permitted to grow until after producing its first full crop before any cutting takes place
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly and explicitly stated in the passage: 'the tree is permitted to grow until after producing its first full crop before any cutting takes place.' The subject, predicate, and object are all directly supported 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 (the passage presents this as general horticultural practice without naming a specific source). The stance is accurately 'asserts' as the passage states this as fact. The sentiment is neutral, matching the passage's informational tone. The time qualifiers are correctly null as the passage provides no specific dates or temporal scope. The context is appropriately empty as the passage discusses coffee trees in general cultivation. The quote is verbatim and directly supports the claim about permitting tree growth until the first full crop is produced.
the branches are severely cut back
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Then, the branches are severely cut back; and thereafter, pruning is carried on annually.' The passage explicitly confirms that coffee tree branches are cut back after the first full crop, exactly as claimed.
- qualifier_fidelity 0.90 pass — All qualifiers are faithful to the passage. The viewpoint is correctly identified as 'author' since the passage presents this as general information without attribution to a named source. The stance 'asserts' is correct - the passage states this as fact. Sentiment 'neutral' matches the passage's objective, technical tone. The time qualifiers are appropriately null since the passage provides relative temporal context ('after producing its first full crop') rather than specific dates. The context 'after first full crop' accurately reflects the passage's temporal restriction on when this action occurs. The quote is verbatim and supports the claim. Minor note: the passage uses 'severely' as an intensifier, which adds emphasis to the cutting action, but this doesn't constitute unfaithfulness to the neutral sentiment, as 'severely' describes the degree of cutting, not a judgmental stance toward it.
pruning is carried on annually
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Then, the branches are severely cut back; and thereafter, pruning is carried on annually.' The quote provided matches the exact language used in the source text, making this fully grounded.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (implicit throughout the instructional text). The stance is properly marked as 'asserts' - the passage states this as fact without dispute. The sentiment is neutral, matching the passage's objective, technical tone. The temporal qualifier 'annually' is accurate and matches the passage's explicit statement. The context correctly specifies the condition 'after branches severely cut back,' which aligns with the passage's sequence: 'Then, the branches are severely cut back; and thereafter, pruning is carried on annually.' The quote is verbatim and directly supports the claim.
- coffee tree produce full crops from year to year sixth to fifteenth year sixth to fifteenth year ⟨as a rule⟩
Coffee trees as a rule produce full crops from the sixth to the fifteenth year
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Coffee trees as a rule produce full crops from the sixth to the fifteenth year, although some trees have given a paying crop until twenty or thirty years old.' The subject, predicate, and object are all explicitly provided with the qualifying phrase 'as a rule.'
- 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 attribution to a named source). The stance is 'asserts' which matches the passage's declarative statement. Sentiment is neutral, appropriate for factual information about crop production. The time qualifiers correctly reflect the passage's statement that trees 'produce full crops from the sixth to the fifteenth year' with valid_from=6 and valid_to=15. The context qualifier 'as a rule' faithfully captures the passage's use of 'as a rule' to indicate this is typical but not universal. The quote is verbatim from the passage and directly supports the claim.
- coffee tree have given paying crop until twenty or thirty years old twenty or thirty years old ⟨some trees⟩
some trees have given a paying crop until twenty or thirty years old
judge verdicts (2)
- groundedness 1.00 pass — This claim is directly stated in the passage. The exact quote 'some trees have given a paying crop until twenty or thirty years old' appears verbatim in the second paragraph, accurately representing what the passage asserts about coffee tree productivity longevity.
- qualifier_fidelity 0.85 pass — The claim is largely faithful to the passage. The viewpoint, stance, sentiment, context ('some trees'), and quote are all accurate and properly extracted. However, there is a minor issue with the 'time' qualifier: the passage does not provide explicit normalized dates for 'valid_from' and 'valid_to'. The passage states 'twenty or thirty years old' as an age range, not as calendar dates or normalized temporal bounds. The claim should either omit valid_from/valid_to (using only 'when') or clearly indicate these represent ages rather than dates. The current representation slightly conflates age with time period, though the intent is understandable.
the trees bear from one-half pound to eight pounds of coffee annually
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Ordinarily the trees bear from one-half pound to eight pounds of coffee annually, although there are accounts of twelve pounds being obtained per tree.' The subject, predicate, and object are all explicitly present with matching language and context.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (presenting factual information about coffee cultivation). The stance of 'asserts' matches the passage's straightforward claim. The sentiment is neutral, appropriate for technical/informational content. The temporal scope 'annually' is directly stated in the passage. The context 'ordinarily' is explicitly used in the passage ('Ordinarily the trees bear...'). The quote is verbatim from the passage and accurately supports the claim about annual yield ranges.
there are accounts of twelve pounds being obtained per tree
judge verdicts (4)
- groundedness 1.00 pass — The claim is directly stated in the passage. The exact quote 'there are accounts of twelve pounds being obtained per tree' appears verbatim, confirming that coffee trees can yield twelve pounds annually according to documented accounts.
- qualifier_fidelity 0.50 fail — Two qualifier errors: (1) STANCE - the passage states 'there are accounts of twelve pounds being obtained per tree' as a factual report, not a question or dispute; the claim incorrectly uses 'questions' stance when the passage presents this neutrally as one possible production level among others. (2) VIEWPOINT - the claim attributes this to 'author' but the passage uses the passive 'there are accounts of', which is more general attribution language, not a clear author assertion; however, this is less critical than the stance error. The context qualifier 'accounts of' is faithful and preserves the passage's epistemic hedging appropriately.
- groundedness 1.00 pass — The claim is directly stated in the passage: 'although there are accounts of twelve pounds being obtained per tree.' The passage explicitly mentions that coffee trees can yield twelve pounds annually, presented as exceptional cases documented in accounts.
- qualifier_fidelity 0.85 pass — The claim is largely faithful to the passage. Viewpoint, stance, and sentiment are all correct—the passage reports this through 'accounts' without attribution to a named source, and the author presents this neutrally. Time qualifiers are appropriately null. The context 'accounts of' accurately reflects the passage's framing that this is not a standard claim but rather something reported in accounts. The quote is verbatim and supports the claim. Minor deduction only for the quote being slightly incomplete in the claim's structure—it could have included 'although' to show this is presented as an exception to the stated range of one-half to eight pounds—but the quoted portion itself is accurate and the context qualifier compensates for this.
When too old to bear profitable yields, the trees on commercial plantations are cut down to the level of the ground
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The exact quote provided ('When too old to bear profitable yields, the trees on commercial plantations are cut down to the level of the ground') appears verbatim in the final paragraph, supporting all elements of the claim 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 (implicit in the expository text).

judge verdicts (2)
- groundedness 0.90 pass — The claim is directly supported by the passage, which states 'is, in fact, more or less grown in every state, if only for domestic use.' The only minor difference is the claim omits 'more or less,' but this does not materially change the meaning and is a negligible rewording.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (implicit narrator). The stance is 'asserts' as the passage states this as fact. The sentiment is neutral, matching the passage's objective tone.

The viewpoint is correctly identified as 'author' (the passage presents this as factual information without attribution to a named source). The stance 'asserts' is appropriate for the declarative statement. The sentiment is neutral as the passage presents this as historical fact without evaluative language. The temporal qualifier 'formerly' matches the passage's framing. The context 'Jamaica' is appropriate and consistent with the passage's restriction of the claim to that geographic location.

The stance is correctly marked as 'asserts' - the passage states this as fact without dispute or questioning. The sentiment is appropriately negative, reflecting the loss of the coffee industry. The time qualifiers are accurate: 'by 1887' matches the passage exactly, and the valid_from/valid_to range (1869-1887) correctly captures the disease appearance in 1869 and the near-disappearance by 1887. The context is appropriately empty as the passage refers to the coffee tree without special restriction to a particular sense or role.

- 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 represented as an assertion. The sentiment is neutral, matching the passage's factual tone. The temporal qualifier correctly specifies 1770 with valid_from=1770 and valid_to=null, consistent with the passage's statement that provides only a specific year without an end date.

it began at once to spread widely over the area of excellent soil
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'When the coffee tree found its true home in southern Brazil in 1770, it began at once to spread widely over the area of excellent soil.' The subject, predicate, object, time, and context all match the passage precisely without requiring outside knowledge or over-generalization.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. All qualifiers are accurate: viewpoint is correctly attributed to 'author' (no named source in passage), stance is 'asserts' (appropriate for factual statement), sentiment is neutral (matches passage tone), time range is appropriate (after 1770), and context 'southern Brazil' is correct. The quote matches verbatim. Minor deduction: the phrase 'widely' in the quote is rendered as 'spread over' in the predicate, which slightly simplifies the passage's language, though this is a minor semantic adjustment rather than a factual error in qualifier fidelity.
The coffee tree grows well in the provinces of Tonkin, Annam, Cambodia, and Cochin-China
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage with the exact quote: 'The coffee tree grows well in the provinces of Tonkin, Annam, Cambodia, and Cochin-China.' No rewording or inference is required.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (no named source given). The stance of 'asserts' matches the declarative statement in the passage. The sentiment 'positive' ('grows well') aligns with the passage's positive framing.

the coffee-tree, _boun_-tree
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in footnote [5], which explicitly says 'the coffee-tree, _boun_-tree (_sejar et boun_)'. This confirms that the coffee-tree is called boun-tree with no rewording needed.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The quote is accurate and the predicate, object, time qualifiers, and context are all correct. The only minor issue is the viewpoint: the passage presents this information in a footnote without attributing it to a named source, so 'author' is appropriate here rather than a specific named source. However, since the passage itself doesn't explicitly name a source for this information, using 'author' (meaning the passage's author/compiler) is a reasonable interpretation. The stance (asserts) and sentiment (neutral) are both appropriate. The context 'botanical/linguistic' accurately captures the nature of the claim. Deducting 0.1 for the slight ambiguity in how 'author' is interpreted when no explicit source is named in the footnote.
amongst which there were the coffee trees
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly says 'amongst which there were the coffee trees, the finest that could be had' when describing the contents of the King's Gardens, fully supporting the claim that the King's Gardens contains coffee trees.

- groundedness 1.00 pass — The claim is directly stated in the passage: 'Like the Arabs in Yemen, the Harari cultivated in small gardens, employing the same ingenious system of irrigation from mountain springs to water the roots of the plants at least once a week during the dry season.' The subject, predicate, and object are all explicitly present without requiring outside knowledge or over-generalization.

Prolonged droughts are fatal
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Prolonged droughts are fatal' explicitly asserts that drought is fatal to the coffee tree. The exact language from the passage supports the subject-predicate-object relationship without requiring any outside knowledge or over-generalization.
- 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 states this as fact. The sentiment 'negative' correctly reflects the harmful connotation of 'fatal'. The time qualifiers are correctly null since the passage provides no temporal scope for this general principle.

The quote 'Prolonged droughts are fatal' appears verbatim in the passage and directly supports the claim that drought is fatal to coffee trees.
it has become the practise to grow catch crops between the rows of coffee trees
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage's opening sentence: 'it has become the practise to grow catch crops between the rows of coffee trees.' The subject, predicate, and object are all explicitly mentioned without any rewording or generalization needed.
- 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 'asserts' accurately reflects the passage's declarative presentation. The sentiment 'neutral' matches the factual tone.

Insects and fungi are the most bothersome pests on most plantations
judge verdicts (2)
- groundedness 0.85 pass — The passage directly states that 'Insects and fungi are the most bothersome pests on most plantations' and extensively describes various insects as principal enemies of the coffee tree. The claim accurately captures this assertion, though it slightly narrows the scope by not mentioning fungi as co-equally bothersome pests.
- qualifier_fidelity 0.85 pass — The claim is largely faithful to the passage. The viewpoint, stance, and sentiment qualifiers are correct - the author asserts the negative claim about insects. The time qualifiers are appropriately null as the passage provides no temporal scope. The context is correctly empty. However, there is a minor issue with the quote: the quoted text states insects AND fungi are the most bothersome pests, but the claim isolates only 'insects' as principal enemies. The quote does support the broader claim about insects being principal enemies (the passage lists many specific insect types as principal foes), but the selected quote is not perfectly precise to the claim's singular focus on insects. The claim itself is well-supported by the passage's discussion of insects being principal enemies.
Insects and fungi are the most bothersome pests on most plantations
judge verdicts (2)
- groundedness 0.70 pass — The passage states that 'Insects and fungi are the most bothersome pests on most plantations' and lists fungi among the chief enemies of the coffee tree. The claim's characterization of fungi as 'principal enemies' is a reasonable rewording of 'most bothersome pests,' though 'principal' specifically emphasizes ranking among pests rather than just being bothersome, which represents minor rewording of the passage's assertion.
- qualifier_fidelity 0.85 pass — The claim is mostly faithful to the passage. The quote accurately supports that fungi are among the most bothersome pests. However, there is a minor issue with the predicate: the claim states fungi are 'principal enemies' but the passage says they are 'most bothersome pests' - these are not quite synonymous. 'Principal' suggests primary or main, while 'most bothersome' indicates severity or annoyance level. The passage does list insects' specific varieties (borers, scale insects, etc.) as principal foes with detailed explanations, while fungi are mentioned but not elaborated upon, suggesting insects may be more 'principal.' The viewpoint, stance, sentiment, time, and context qualifiers are all faithful to the passage.
the so-called "leaf-miner" being especially troublesome
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly says 'the so-called "leaf-miner" being especially troublesome' when discussing insects that attack coffee-tree leaves, fully supporting the assertion that the leaf-miner is especially troublesome to the coffee tree.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (implicit assertion in the text). The stance is 'asserts' which matches the declarative framing. The sentiment is negative, appropriate given 'troublesome'. The time qualifiers are correctly null as the passage provides no temporal specification. The context is appropriately empty as no specific sense or role restriction is mentioned. The quote appears verbatim and supports the claim.
Plantations having from 300,000 to 400,000 trees are common
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage, which explicitly states 'Plantations having from 300,000 to 400,000 trees are common,' confirming that coffee plantations typically contain coffee trees in these quantities.
- 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 observation 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 informational tone. The time qualifiers are correctly null since the passage provides no specific temporal scope for this general statement about typical plantation sizes. The context is appropriately empty as the passage does not restrict the claim to a particular sense or role. The quote appears verbatim in the passage and directly supports the claim that typical plantations contain 300,000-400,000 trees.
One plantation near Ribeirao Preto has 5,000,000 trees
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'One plantation near Ribeirao Preto has 5,000,000 trees' clearly establishes that a plantation near Ribeirao Preto contains coffee trees (the context makes clear these are coffee trees, as the entire passage discusses coffee plantations).
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage makes an objective statement without naming a specific source). The stance is correctly marked as 'asserts' (a straightforward factual claim). The sentiment is neutral, matching the passage's tone. The time is correctly null since no specific date is given for this particular plantation. The context is appropriately empty as no specific sense or role restriction is mentioned. The quote appears verbatim in the passage and directly supports the claim about the 5,000,000 trees.
containing, in all, from 7,500,000 to 8,000,000 coffee trees
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage, which explicitly states that one planter owns 'thirty-two adjacent plantations containing, in all, from 7,500,000 to 8,000,000 coffee trees.' The claim accurately captures this information without adding outside knowledge or over-generalization.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The quote is verbatim and supports the claim. Viewpoint, stance, and sentiment are all appropriate (author asserting neutrally). Context correctly specifies the thirty-two adjacent plantations. However, there is a minor issue: the passage does not explicitly attribute this statement to a named source or the author - it presents the information as objective fact. The use of 'author' as viewpoint is acceptable given the passage structure, but the claim could be slightly more precise. Time qualifiers are correctly set to null since no specific date is given for this particular plantation statistic. Overall fidelity is high with only this minor ambiguity in viewpoint attribution.
There are fifteen plantations having more than 1,000,000 trees each
judge verdicts (2)

The stance is appropriately 'asserts' as the passage presents this as factual information. The sentiment is neutral, matching the objective tone of the passage. The time qualifiers are correctly null since the passage provides no specific temporal reference for this particular claim (unlike the 1922 date mentioned for Ribeirao Preto municipality). The context accurately reflects the specific subset of plantations described. The quote appears verbatim in the passage and directly supports the claim about fifteen plantations having more than 1,000,000 trees each.

- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage presents factual statements without attribution to named sources). The stance is appropriately marked as 'asserts' since the passage states this as fact. The sentiment is neutral, matching the objective, informational tone of the passage. The time qualifier is correctly set to null since the passage provides no specific date for this particular statement about the five plantations. The context accurately specifies the subset being discussed ('five plantations with more than 2,000,000 trees'). The quote is verbatim from the passage and directly supports the claim about these plantations having coffee trees.

judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the opening sentence of the passage: 'The virgin land in the interior of the island is admirably adapted to the coffee tree.' The wording matches exactly, including the specific evaluative language ('admirably adapted') and contextual details (virgin land, interior of island, coffee tree).
- 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 a direct statement rather than attributing it to a named source). The stance 'asserts' appropriately reflects the declarative nature of the statement. The sentiment 'positive' correctly captures the favorable connotation of 'admirably adapted.'

- 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 historical fact 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 neutral presentation.

Dr. James Douglas published in London (1727) his _Arbor yemensis fructum cofe ferens, or a description and history of the Coffee Tree_
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly and fully supported by the passage. The exact quote provided matches the text stating that Dr. James Douglas published in London in 1727 his work which is described as 'a description and history of the Coffee Tree'.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The quote is verbatim, the subject/predicate/object are accurate, the time qualifiers (when: 1727, valid_from: 1727, valid_to: 1727) correctly reflect the publication date, the context (London) is correct, and the sentiment (neutral) appropriately matches the passage's straightforward reporting. However, the viewpoint is labeled as 'author' when the passage does not attribute this statement to a named source as the author of the passage itself—it is simply a historical fact being reported. The viewpoint should be 'passage' or the statement should clarify that this is historical documentation rather than authorial attribution. This is a minor issue but represents a slight deviation from strict qualifier fidelity regarding how the viewpoint is framed.
DOUGLAS, JAMES. Arbor yemensis fructum cofe ferens: or, A description and history of the coffee tree. _London_, 1727.
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The bibliographic entry explicitly describes Douglas's 1727 work as 'A description and history of the coffee tree,' which directly supports the predicate 'described and documented history of' the coffee tree.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The viewpoint, stance, sentiment, and time are all correctly represented. The quote is verbatim from the passage and accurately supports the claim. Minor deduction: the context field is empty when it could note this refers to the coffee tree as a botanical subject, though this is minor since the object already specifies 'coffee tree'. All essential qualifiers are faithful.
