13 extractive question-and-answer pairs built from 80993440321561442011-1, published by ncdc.mohfw.gov.in. The source is a 3-page publication. Source-evidenced topics include influenza, rna virus, orthomyxoviridae, type b, type c, subtypes, hemagglutinin, neuraminidase. Every answer is a verbatim span of text the source prints, and each row carries the passage it sits in, its offset in that passage, the source quote, the page and the location in the document, so any row can be checked against the original. Question types in the export: 6 list, 5 relationship, 2 factual. 11 of the 13 pairs (84.6%) ask explanatory questions; the remaining 2 are factual or table-based questions. 100.00% of rows pass the corpus quality gate.
This dataset contains 13 extractive question-and-answer pairs derived from a publication by the National Centre for Disease Control (NCDC) in India. The questions cover topics such as influenza virus taxonomy, transmission, genetic changes, and public health impacts. Answers are verbatim excerpts from the source document, ensuring traceability. The dataset includes explanatory, factual, and list-based questions, with most focusing on relationships and explanations. The source document spans three pages and provides detailed information on influenza virus characteristics, subtypes, and epidemiological factors.
