About this dataset

24 extractive question-and-answer pairs built from crop guide commercially important crops, published by agritech.tnau.ac.in. The source is a 4-page publication. Source-evidenced topics include cultivation guide, growth habit, spacing, seed rate, crop duration, yield, annual herb, medium sized. 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: 20 factual, 3 list, 1 definition. 4 of the 24 pairs (16.7%) ask explanatory questions; the remaining 20 are factual or table-based questions. 100.00% of rows pass the corpus quality gate.
