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.

[Q]: 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.
[A]: How many more people lived in Kabuls by 1878 compared to 1700?


[Q]: Passage: East Fife secured the 2007-08 Scottish Third Division title after beating East Stirlingshire F.C. at Firs Park, Falkirk 3-0 on 15 March 2008. This gave them a points total of 74, 26 points ahead of Stranraer who could post the next best total in the league of 69 points if they were to win their remaining fixtures. This was East Fifes first league title for 60 years and their first piece of silverware since 1954. On 14 April 2009 their manager David Baikie resigned from his position.

[Q]: Passage: In the Bulgarian census of 2011, a total of 48,945 people declared themselves to be Roman Catholics, up from 43,811 in the previous census of 2001 though down as compared to 53,074 in 1992. The vast majority of the Catholics in Bulgaria in 2001 were ethnic Bulgarians and the rest belonged to a number of other ethnic groups such as Croatians, Italians, Arabs and Germans. Bulgarian Catholics live predominantly in the regions of Svishtov and Plovdiv and are mostly descendants of the heretical Christian sect of the Paulicians, which converted to Roman Catholicism in the 16th and 17th centuries. The largest Roman Catholic Bulgarian town is Rakovski in Plovdiv Province. Ethnic Bulgarian Roman Catholics known as the Banat Bulgarians also inhabit the Central European region of the Banat. Their number is unofficially estimated at about 12,000, although Romanian censuses count only 6,500 Banat Bulgarians in the Romanian part of the region. Bulgarian Catholics are descendants of three groups. The first were converted Paulicians from the course of the Osam river  and around Plovdiv are the second  group, while the third  one is formed by more recent Eastern Orthodox converts.
[A]:
How many fewer people identified as Roman Catholics in 2011 than in 1992?
