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: Over the years the city has been home to people of various ethnicities, resulting in a range of different traditions and cultural practices. In one decade, the population increased from 427,045 in 1991 to 671,805 in 2001. The population was projected to reach 915,071 in 2011 and 1,319,597 by 2021. To keep up this population growth, the KMC-controlled area of  has expanded to  in 2001. With this new area, the population density which was 85 in 1991 is still 85 in 2001; it is likely to jump to 111 in 2011 and 161 in 2021.
Example Output: How many more people populated the city in 2001 than in 1991?

Example Input: Passage: The Hindus were found mainly in Jammu Division, where they constituted a little less than 60% of the population. In the Kashmir Valley, the Hindus represented "524 in every 10,000 of the population (i.e. 5.24%), and in the frontier wazarats of Ladhakh and Gilgit only 94 out of every 10,000 persons (0.94%)." In the same Census of 1901, in the Kashmir Valley, the total population was recorded to be 1,157,394, of which the Muslim population was 1,083,766, or 93.6% and the Hindu population 60,641. Among the Hindus of Jammu province, who numbered 626,177 (or 90.87% of the Hindu population of the princely state), the most important castes recorded in the census were "Brahmin (186,000), the Rajputs (167,000), the Khatri (48,000) and the Thakkars (93,000).".
Example Output: How many Rajputs in the population than Khatri?

Example Input: Passage: Josh Freeman threw for 237 yards and threw five touchdown passes, tying a franchise record, as Tampa Bay routed Seattle 38-15. In the first quarter, Matt Hasselbeck scrambled for a 1-yard touchdown to give Seattle a 7-0 lead. However, Hasselbeck suffered a muscle strain on the play, and was sidelined for the remainder of the game. Backup quarterback Charlie Whitehurst was forced to take over for Seattle. Micheal Spurlock returned the ensuing kickoff 79 yards to the Seattle 17-yard line, setting up a Connor Barth field goal. Tampa Bay scored 31 unanswered points, including two touchdown passes apiece from Freeman to Kellen Winslow and Mike Williams.
Example Output:
How many TD passes did Freeman throw?
