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.

Let me give you an 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 Pondichery 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.
The answer to this example can be: Which french settlement did the British capture first, Chandernagore or Pondicherry?
Here is why: 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.

Passage: Late in the 18th Century, Qing dynasty set about a momentous task, the creation of the Siku Quanshu. The Qianlong Emperor ordered the creation of the Siku Quanshu in 1772. Local and Provincial officers were in charge of locating and collecting important books. The Qianlong Emperor encouraged owners of rare or valuable books to send them to the capital, however few actually did due to concerns about the Literary Inquisition. Towards the end of 1772, seeing that only a limited number of people actually handed in books, the Qianlong Emperor issued imperial decrees stressing that books would be returned to their owners once the compilation was finished and that owners of the books would not be persecuted if their books contained anti-Manchu sentiment. Less than three months after the issue of this decree, four to five thousand books were handed in. By March of 1773, an editorial board was created in Beijing to gather and review books brought to them. This board included over 361 scholars, with Ji Yun and Lu Xixiong as chief editors. There was around 3,826 scribes who copied every word by hand. These copyists were not paid in coinage but in government positions after they had transcribed a set amount of the encyclopedia. It took over a decade until the encyclopedia was completed and all seven copies were distributed.
Answer:
How many chief editors did the board have?
