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.

Example Input: Passage: Anaukpetlun then brought trans-Salween Shan states under his rule in the 1620s. In February 1622, his forces  took Kengtung, which had been held by an ally of Lan Xang, after a fierce battle. Reinforced Burmese armies led by the king's brothers Thalun and Minye Kyawswa II invaded the Chinese Shan states in present-day southern Yunnan in May 1622. For the next 20 months, Burmese forces chased Kenghung troops. Finally in January 1624, Kenghung and Kengyun both surrendered. Kengyun promptly rebelled the following year but it was put down in December 1626 by the king's brothers. By then, Nyaungyan and Anaukpetlun had restored much of Bayinnaung's empire. Only Siam and Lan Xang remained outside the Restored Toungoo Empire. But the Burmese would not overstretch again. They would not launch major invasions against these neighbours until the 1760s.
Example Output: Anaukpetlun's forces took Kengtung how many years before Kenghung and Kengyun both surrendered?

Example Input: Passage: For the last time Fairfax's appearance in arms helped to shape the future of the country, when George Monck invited him to assist in the operations about to be undertaken against John Lambert's army. In December 1659 he appeared at the head of a body of Yorkshire gentlemen, and such was the influence of Fairfax's name and reputation that 1,200 horse quit Lambert's colours and joined him. This was speedily followed by the breaking up of all Lambert's forces, and that day secured the restoration of the monarchy. For these actions, along with his honourable conduct in the civil war, he was spared from the wave of Royalist retributions. In April 1660 Fairfax was re-elected MP for Yorkshire in the Convention Parliament. He was put at the head of the commission appointed by the House of Commons to wait upon Charles II, at the Hague and urge his speedy return. Fairfax provided the horse on which Charles rode at his coronation. The remaining eleven years of the life of Lord Fairfax were spent in retirement at his seat in Yorkshire. His wife died in 1665 and Fairfax died at Nunappleton in 1671. He was buried at Bilbrough, near York.
Example Output: How many months after Fairfax appeared at the head of a body of Yorkshire gentlemen which was the influence of his name and reputation was he re-elected MP for Yorkshire in the Convention Parliament?

Example Input: Passage: As of the census of 2000, there were 218,590 people, 79,667 households, and 60,387 families residing in the county.  The population density was 496 people per square mile (192/km²). There were 83,146 housing units at an average density of 189 per square mile (73/km²). The racial makeup of the county was 86.77% Race (United States Census), 9.27% Race (United States Census), 0.23% Race (United States Census), 1.52% Race (United States Census), 0.06% Race (United States Census), 0.69% from Race (United States Census), and 1.47% from two or more races.  1.91% of the population were Race (United States Census) or Race (United States Census) of any race. 22.5% were of German people, 13.1% Irish people, 9.8% Italian people, 9.2% English, 8.1% "American" and 6.0% Polish ancestry.
Example Output:
How many in percent from the census weren't American?
