user: 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? If you are still confused, see the following example:
Passage: The outbreak of the Seven Years' War in Europe in 1756 resulted in renewed conflict between French and British forces in India. The Third Carnatic War spread beyond southern India and into Bengal where British forces captured the French settlement of Chandernagore in 1757. However, the war was decided in the south, where the British successfully defended Madras, and Sir Eyre Coote decisively defeated the French, commanded by Comte de Lally at the Battle of Wandiwash in 1760. After Wandiwash, the French capital of Pondicherry fell to the British in 1761. The war concluded with the signing of the Treaty of Paris in 1763, which returned Chandernagore and Pondichéry to France, and allowed the French to have "factories" in India but forbade French traders from administering them. The French agreed to support British client governments, thus ending French ambitions of an Indian empire and making the British the dominant foreign power in India.
Solution: Which french settlement did the British capture first, Chandernagore or Pondicherry?
Reason: This is a good question since it involves a comparison around a particular event, "British capturing the French settlement", which requires looking at more than a single sentence.

Now, solve this instance: Passage: While the silver threepence was minted as a currency coin until nearly the middle of the 20th century, it is clear that the purpose of the coin changed during the reign of George III of the United Kingdom (1760-1820). In the first two years of minting, 1762 and 1763, the coin was obviously produced for general circulation as examples are generally found well worn; on the other hand, coins from the late issue (1817-20) are usually found in very fine condition, indicating that they were probably issued as Maundy money. Over the length of the reign there were several different designs of obverse and reverse in use. Threepences were issued in 1762-63, 1765-66, 1770, 1772, 1780, 1784, 1786, 1792, 1795, 1800, 1817, 1818, and 1820. From 1817 the dimensions of the coin were reduced to a weight of 1.4 grams and diameter of 16 millimetres, following the Great Recoinage of 1816. The inscription on the obverse reads  up to 1800, and  from 1817. The reverse inscription reads  up to 1800 and  from 1817.

assistant: For how many total years were threepences issued?
