African ones such as malaria and yellow fever
judge verdicts (2)
- groundedness 0.70 pass — The passage states 'African ones such as malaria and yellow fever' when discussing diseases, directly supporting that malaria is characterized as an African disease. This is stated with minor rewording from the original phrasing but accurately reflects what the passage asserts.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The viewpoint is correctly identified as 'author' (the passage presents this directly without attribution to a named source). The stance 'asserts' and sentiment 'neutral' are appropriate. The time qualifiers (all null) correctly reflect that the passage provides no specific temporal scope. The context is appropriately empty since the passage does not restrict malaria to a particular sense or role. The quote 'African ones such as malaria and yellow fever' appears verbatim and supports the claim. Minor note: The passage frames malaria as 'African disease' in the context of diseases that affected labor force composition historically, which is accurately captured. Deduction of 0.1 only for the slightly reductive nature of labeling malaria as purely 'African' when the passage actually discusses it in relation to disease ecology and labor history—though this is a minor semantic issue rather than a qualifier fidelity problem.
