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: Kabuls population is estimated to have been about 10,000 in 1700, 65,000 by 1878, and 120,000 by 1940. More recently, the population was around 500,000 in 1979, whilst another source claims 337,715 as of 1976. This figure rose to about 1.5 million by 1988, before dramatically dropping in the 1990s. Kabul became one of the fastest growing cities in the world, with its population growing fourfold from 2001 to 2014. This was partly due to the return of refugees after the fall of the Taliban regime, and partly due to Afghans moving from other provinces mainly due to war between Taliban insurgents and Afghan government forces in their native areas as well as looking for labor. This resulting rapid urbanization mean that many residents today live in informal settlements. Shanty mud-brick homes on the mountainsides and steep hills have been built by them and these are usually poverty-stricken, not connected to the water and electricity grid. Although the settlements are illegal, they have been tolerated by authorities. In 2017 Kabul Municipality started a project to paint the homes in these settlements in bright colors in an effort to "cheer up" residents.
Example Output: How many more people lived in Kabuls by 1878 compared to 1700?

Example Input: Passage: The film was released in the United States on July 25, 2008. In an interview with Entertainment Weekly, Carter said that if I Want to Believe proved successful, he would propose a third movie that would return to the television series mythology and focus on the alien invasion foretold within the series, due to occur in December 2012. The film grossed $4 million on its opening day in the United States. It opened fourth on the U.S. weekend box office chart, with a gross of $10.2 million. By the end of its theatrical run, it had grossed $20,982,478 domestically and an additional $47,373,805 internationally, for a total worldwide gross of $68,369,434. Among 2008 domestic releases, it finished in 114th place. The films stars both claimed that the timing of the movies release, a week after the highly popular Batman film The Dark Knight (film), negatively affected its success. The film received mixed to negative reviews. Metacritic, which assigns a standard score rating out of 100 reviews from mainstream film critics, reported "mixed or average" reviews, with an weighted mean score of 47 based on 33 reviews. Rotten Tomatoes reported that 32% of 160 listed film critics gave the film a positive review, with an average rating of 4.9 out of 10. The website wrote of the critics consensus stating; "The chemistry between leads David Duchovny and Gillian Anderson do live up to The X-Files televised legacy, but the roving plot and droning routines make it hard to identify just what were meant to believe in.".
Example Output: How many dollars did the film  I Want to Believe gross worldwide than in the U.S?
