  • Hemileia vastatrix causes leaf spot disease

    judge verdicts (4)
    • groundedness 1.00 pass — The claim is directly supported by the passage. The SADEBECK reference explicitly states 'Beobachtungen und Bemerkungen ueber die durch Hemileia vastatrix verursachte Blattfleckenkrankheiten der Kaffeebaeume' (Observations and remarks on the leaf spot disease of coffee trees caused by Hemileia vastatrix), published in 1895, which directly confirms that Hemileia vastatrix causes leaf spot disease.
    • qualifier_fidelity 0.50 fail — Multiple qualifier issues: (1) VIEWPOINT: The claim attributes the statement to 'author' but the passage identifies the specific source as 'SADEBECK, R.' - the viewpoint should be 'Sadebeck' not 'author'. (2) TIME: The claim specifies 'when': 1895, but the passage provides only the publication year without indicating the statement's temporal scope; the time qualifier should either be null or clarified that 1895 is only the publication date. (3) QUOTE: The provided quote is incomplete and contains a transcription error ('the through' instead of 'through'); the correct quote from the passage is 'the durch Hemileia vastatrix verursachte Blattfleckenkrankheiten der Kaffeebaeume' or in the German text 'Beobachtungen und Bemerkungen ueber die durch Hemileia vastatrix verursachte Blattfleckenkrankheiten der Kaffeebaeume'.
    • groundedness 1.00 pass — The claim is directly stated in the passage. The Sadebeck entry explicitly mentions 'Hemileia vastatrix verursachte Blattfleckenkrankheiten der Kaffeebaeume' (Hemileia vastatrix causing leaf spot disease of coffee trees), which directly supports the subject-predicate-object relationship claimed.
    • qualifier_fidelity 0.85 pass — The claim's qualifiers are largely faithful to the passage. Viewpoint (Sadebeck), stance (asserts), sentiment (neutral), and time (null, as no temporal scope is given) are all correct. The quote is present in the passage and supports the claim. However, there is a minor issue with the quote itself: it should read 'Blattfleckenkrankheiten' (plural) not 'Blattfleckenkrankheiten' as stated, though this is a translation/interpretation matter. The context qualifier is appropriately empty since the passage does not restrict this to a specific sense or role. The only minor deduction is for the quote containing the German article 'die' before 'durch' which makes it slightly incomplete as a standalone phrase, though it does appear verbatim in the passage title.

    judge verdicts (2)
    • groundedness 1.00 pass — The claim is directly stated in the passage. The exact quote provided matches the text, which explicitly says that Hemileia vastatrix attacked Ceylon's coffee industry in 1869 and eventually destroyed it.
    • 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 properly marked as 'asserts' - the passage straightforwardly states the disease attacked and destroyed the industry without dispute or questioning. The sentiment is accurately negative, reflecting the destructive nature described. The time qualifier correctly specifies 1869 with valid_from matching the attack date and valid_to as null since the passage provides no end date for the destruction. Context is empty, which is appropriate as the passage does not restrict the claim to a specific sense or role. The quote is verbatim from the passage and directly supports all elements of the claim.
