Definition: 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.
Input: Passage: The US had a gold stock of 1.9 million ounces (59 t) in 1862. Stocks rose to 2.6 million ounces (81 t) in 1866, declined in 1875 to 1.6 million ounces (50 t) and rose to 2.5 million ounces (78 t) in 1878. Net exports did not mirror that pattern. In the decade before the Civil War net exports were roughly constant; postwar they varied erratically around pre-war levels, but fell significantly in 1877 and became negative in 1878 and 1879. The net import of gold meant that the foreign demand for American currency to purchase goods, services, and investments exceeded the corresponding American demands for foreign currencies. In the final years of the greenback period (1862-1879), gold production increased while gold exports decreased. The decrease in gold exports was considered by some to be a result of changing monetary conditions. The demands for gold during this period were as a speculative vehicle, and for its primary use in the foreign exchange markets financing international trade. The major effect of the increase in gold demand by the public and Treasury was to reduce exports of gold and increase the Greenback price of gold relative to purchasing power.
Output:
Was the gold stock of the United States higher in 1862 or 1866?
