1926 extractive question-and-answer pairs built from Indian Minerals Yearbook, published by ibm.gov.in. 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. 1089 of the 1926 pairs (56.5%) are explanatory questions and 837 restate a figure. 97.66% of rows pass the corpus quality gate.
