- Hemileia vastatrix has been found in nearly all coffee-producing countries coffee-producing countries since it destroyed Ceylon's coffee industry
As it has since been found in nearly all coffee-producing countries
judge verdicts (4)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'As it has since been found in nearly all coffee-producing countries, it has become a nightmare in the dreams of all coffee planters.' The subject (Hemileia vastatrix), predicate (has been found in), and object (nearly all coffee-producing countries) are all explicitly stated without requiring outside knowledge or over-generalization.
- qualifier_fidelity 0.50 fail — The 'time' qualifier is unfaithful. The passage states the fungus 'has since been found in nearly all coffee-producing countries' where 'since' refers to the time after it destroyed Ceylon's coffee industry (mentioned in chapter XV). However, the claim's time object uses 'when: "since destroyed Ceylon's industry"' which is imprecise phrasing that doesn't clearly establish the temporal relationship. The time should be represented as a period starting after the Ceylon destruction, not as an unclear reference. Additionally, while the quote is verbatim and the viewpoint/stance/sentiment appear appropriate, the temporal qualifier needs clearer normalization to represent 'since [the Ceylon destruction]' as a defined starting point rather than the vague formulation provided.
- groundedness 1.00 pass — The claim is directly stated in the passage: 'As it has since been found in nearly all coffee-producing countries, it has become a nightmare in the dreams of all coffee planters.' The subject, predicate, and object are all explicitly present without requiring outside knowledge or over-generalization.
- qualifier_fidelity 0.85 pass — Mostly faithful qualifiers. Viewpoint is correctly 'author' (passage uses 'it has been found' without attribution to a named source). Stance 'asserts' is correct. Sentiment 'negative' is appropriate given the context of the disease being 'dreaded' and 'feared'. Time qualifier is slightly imprecise: the passage states 'since it has...been found in nearly all coffee-producing countries' but does not explicitly link this to the destruction of Ceylon's industry as a temporal marker - the 'since' in the passage refers to after the disease was identified, not specifically after Ceylon's destruction. This is a minor temporal imprecision, but the quote accurately reflects passage language.
a fungus related to the wheat rust
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly describes Hemileia vastatrix as 'a fungus related to the wheat rust' when explaining the cause of Ceylon leaf disease.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage states this as a fact, not attributed to a named source). The stance is 'asserts' which matches the declarative nature of the passage. Sentiment is neutral, which is appropriate for this factual statement. Time qualifiers are correctly null since the passage provides no temporal scope for this relationship. Context is empty, which is appropriate as the passage does not restrict this claim to a particular sense or role. The quote 'a fungus related to the wheat rust' appears verbatim in the passage and directly supports the claim.
Ceylon leaf disease, which is caused by the _Hemileia vastatrix_
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly and explicitly stated in the passage: 'the so-called Ceylon leaf disease, which is caused by the _Hemileia vastatrix_, a fungus related to the wheat rust.' The subject, predicate, and object match the passage exactly without any rewording 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 factual information, not attributed to a named source). The stance is appropriately 'asserts' as the passage states the causal relationship definitively. The sentiment is neutral, matching the passage's objective tone. The time qualifiers are correctly null as the passage provides no specific temporal scope for the causal relationship itself. The context is appropriately empty as no specific sense or role restriction applies to Ceylon leaf disease. The quote is verbatim from the passage and directly supports the claim.
