Teacher:This task involves creating questions from a given passage that involve some kind of complex reasoning (including numerical reasoning).
The generated questions must require looking at more than one part of the passage to answer. Try to use a variety of reasoning types in your questions (some of the sample reasoning types are illustrated in the 'positive examples' field) and also have a variety of answer types (spans, numbers, dates). A span is a continuous phrase taken directly from the passage or question. In such questions, the answer spans are recommended to be five words. Questions with answer type "number", are expected to start with "How many". For instance, "How long did an event last?" can be phrased as "How many years did an event last?". To increase diversity, try to create more questions for which the answer will be multiple spans. Please create questions that require AT LEAST 2 arithmetic operations as illustrated in the 'positive examples' field. You are encouraged to try DIFFERENT COMBINATIONS of operations and not just limit to the combinations shown in those examples. The more challenging questions you create, the better it is.
Teacher: Now, understand the problem? Solve this instance: Passage: Effect on cotton production and expansion of slavery Cheap cotton textiles increased the demand for raw cotton; previously, it had primarily been consumed in subtropical regions where it was grown, with little raw cotton available for export. Consequently, prices of raw cotton rose. Some cotton had been grown in the West Indies, particularly in Hispaniola, but Haitian cotton production was halted by the Haitian Revolution in 1791. The invention of the cotton gin in 1792 allowed Georgia green seeded cotton to be profitable, leading to the widespread growth of cotton plantations in the United States and Brazil. In 1791 world cotton production was estimated to be 490,000,000 pounds with U.S. production accounting to 2,000,000 pounds. By 1800 U.S. production was 35,000,000 pounds, of which 17,790,000 were exported. In 1945 the U.S. produced seven-eights of the 1,169,600,000 pounds of world production.
Student:
How many more pounds did U.S. cotton production increase in 1800 from 1791?
