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: 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.

Ex Output:
How many more people lived in Kabuls by 1878 compared to 1700?

Passage: The Giants returned home for another divisional battle, this time against the Washington Redskins. Washington had swept the Giants last year, and drafted quarterback Robert Griffin III with the second overall pick in the 2012 NFL Draft. The Redskins took a three-point lead late in the game, but a 77-yard touchdown pass from Manning to Victor Cruz in the last minutes of the game allowed the Giants to claim the victory. With the win, the Giants improved to 5-2 and won their first NFC East game of the season.

Ex Output:
How many wins did the Giants have after this game?

Passage: From the 17th century onwards, interest in the old library, with its manuscripts and incunabulae, went into decline and the modern library in the Jesuit College came to the fore. In 1756, the oldest university library was finally closed down and its books, 2,787 volumes, were incorporated into the Court Library, of which Gerard van Swieten was then director. After the dissolution of the Jesuit order (1773), the new "Academic Library" was created out of the book collections of the five Lower Austrian Colleges and a large number of duplicates from the Court Library. This was opened on 13 May 1777, the birthday of Maria Theresa of Austria, in the building of the Academic College. Initially, the stock consisted of some 45,000 books and during Emperor Joseph IIs dissolution of the monasteries, this was soon considerably extended. In contrast to its antecedents, the new library was open to the general public. Between 1827 and 1829, it acquired the classicist extension (Postgasse 9) to the Academic College, in which it was to be accommodated until 1884. In this year, the main library, with some 300,000 books, moved to Heinrich von Ferstels new Main Building on the Ring, where stacks for some 500,000 volumes had already been prepared. With an annual growth of up to 30,000 volumes, the surplus space was soon filled. Book storage space had to be extended continuously. One hundred years later, the complete library, including departmental and subject libraries, comprised more than 4.3 million volumes. Today, Viennas University Library is the largest collection of books in Austria, still facing problems of space. In addition to the Main Library, which alone has to cope with an annual growth of 40,000 volumes, it includes three Faculty Libraries, 32 Subject Libraries and 26 Departmental Libraries.

Ex Output:

How many Faculty Libraries, Subject Libraries, and Departmental Libraries does Viennas University Library have?
