damage from leaf diseases difficult to combat
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'there has been a progressive decrease on account of damage from leaf diseases difficult to combat.' The passage explicitly asserts that leaf diseases cause damage to coffee and notes this damage is difficult to combat.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. Viewpoint correctly identifies 'author' as the source (no named source provided). Stance correctly asserts the relationship. Sentiment is negative as appropriate. Time qualifiers are correctly null since the passage provides no specific temporal scope for this causal relationship. Context appropriately captures the 'difficult to combat' restriction. The quote is verbatim and supports the claim. Minor deduction: the quote should ideally include the full phrase 'damage from leaf diseases difficult to combat' to fully encompass the context qualifier, though the excerpt used does support the claim.
which had appeared in 1869
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'the plantations were suffering severely from the leaf disease, which had appeared in 1869.' The subject (leaf disease), predicate (appeared in), object (Ceylon, implied by context), and time (1869) are all explicitly supported.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage does not name a specific source for this fact). The stance 'asserts' is appropriate as the passage presents this as factual information. The sentiment 'negative' is faithful given the context of disease causing harm to coffee plantations. The time qualifier with 'when': 1869 matches the passage exactly ('which had appeared in 1869'). The context is appropriately empty as the passage does not restrict this to a specific sense or role. The quote 'which had appeared in 1869' appears verbatim in the passage and directly supports the claim.
- arabica has been driven out of districts below 3,500 feet altitude by leaf disease ⟨districts below 3,500 feet altitude⟩
The _arabica_ variety has practically been driven out of the districts below 3,500 feet altitude by the leaf disease
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly and explicitly stated in the passage's opening sentence. The exact wording matches the passage: 'The _arabica_ variety has practically been driven out of the districts below 3,500 feet altitude by the leaf disease.'
- qualifier_fidelity 0.90 pass — Nearly all qualifiers are faithful. The quote is verbatim and accurately supports the claim. Viewpoint, stance, sentiment, time, and context are all appropriate and faithful to the passage. Minor note: The passage uses 'author' implicitly (no named source is provided), so 'author' as viewpoint is correct. The only very minor consideration is that 'practically' in the original suggests a degree of approximation rather than absolute certainty, but this is adequately captured by the predicate 'has been driven out' which inherits that nuance from the source material. All qualifiers match the passage's framing.
Even then, the plantations were suffering severely from the leaf disease
judge verdicts (2)
- groundedness 0.70 pass — The claim is supported by the passage, which directly states 'Even then, the plantations were suffering severely from the leaf disease, which had appeared in 1869.' However, the temporal framing is slightly imprecise: the passage indicates the disease appeared in 1869 and was causing severe suffering by 1873, but the claim's time notation 'by 1873' could be clearer that this represents the timeframe when suffering was already occurring (not just beginning).
- qualifier_fidelity 0.85 pass — The claim is largely faithful to the passage. Viewpoint, stance, and sentiment are all correct - the author asserts this as fact with negative sentiment. The quote is verbatim and accurately supports the claim. However, there is a minor issue with the time qualifier: the passage states the leaf disease 'had appeared in 1869' and by 1873 plantations 'were suffering severely from' it, so valid_from should be 1869 (correct) but the 'when' should be 1873 or the timeframe should be clarified as a range (1869-1887). The current formulation 'by 1873' with valid_from 1869 is slightly imprecise about whether the severe suffering began in 1869 or 1873 - the passage indicates the disease appeared in 1869 but severe suffering is documented by 1873. This is a minor temporal ambiguity rather than a clear error.
as the coffee trees were affected by the leaf disease
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'as the coffee trees were affected by the leaf disease, this land was turned to tea.' The passage explicitly confirms that coffee trees were affected by a leaf disease, which caused the decline of Ceylon's coffee production.
- 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' as the passage states this as fact. The sentiment is negative, reflecting the harmful impact of disease. The time qualifier is appropriately null since the passage does not specify when the leaf disease affected the trees (only that it appeared around 1869). The context is empty as appropriate since the passage does not restrict this to a specific sense or role. The quote appears verbatim in the passage and directly supports the claim.
