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.

Ex 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.

Ex Output:
How many more people populated the city in 2001 than in 1991?

Passage: The Chiefs took an early lead on a 30-yard pass from Tyler Thigpen to Mark Bradley.  The Chiefs defense continued to show improvement in the red zone, limiting the Chargers to two field goals instead of two touch downs.  At the end of the first half, Thigpen threw a pass to 34&#160;yard touchdown pass to Tony Gonzalez. However, the extra point snap was botched and an attempt at a quick pass failed. The Chargers controlled the second half better than the first, scoring two touchdowns and leading the Chiefs by 7 at the end of the fourth quarter.  The Chiefs' final drive ended with a 3-yard touchdown pass to Gonzalez. A 1-point PAT would tie the game. However, Herm Edwards told Thigpen to go for two, explaining in a post-game interview that the defense was too beat up for overtime play.  The resulting two-point conversion ended in an incomplete pass.  The Chiefs lost by one point.

Ex Output:
How many points did the Chiefs score in the first half?

Ex Output:

How many yards was McNabb's touchdown pass?
