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.

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.
How many more people lived in Kabuls by 1878 compared to 1700?

Passage: Estimates for the number of Roman Catholics vary from 70% of the population, to as much as 90%. The CIA Factbook lists 92% of the country is Catholic, but only 20% are practicing regularly or weekly at a church service. The Jewish population is about 300,000 (around 0.75% of the population), the community numbered about 400,000 after World War II, but the appeal of Israel and economic and cultural pressures at home led many to leave; recent instability in Israel has resulted in a modest reversal of the trend since 2003. Islam in Argentina number about 500,000-600,000, or approximately 1.5% of the population; 93% of them are Sunni. Buenos Aires is home to one of the largest mosques in Latin America. A recent study found that approximately 11% of Argentines are non-religious, including those who believe in God, though not religion, agnostics (4%) and atheists (5%). Overall, 24% attended religious services regularly. Protestants were the only group in which a majority regularly attended services.
How many less are in the Jewish population than that of after WWII?

Passage: In 1783, the Cataraqui region was selected by the British as a location to settle United Empire Loyalists who had fled the United States after the American War of Independence. The centre of the region, a community focused on the old fort, would eventually become the city of Kingston. General Sir Frederick Haldimand, Governor of the Province of Quebec, ordered Major John Ross, commander at Oswego, to repair and rebuild the fort to accommodate a military garrison. This was done by a force of 422 men and 25 officers. By October 1783, a lime kiln, hospital, barracks, officers' quarters, storehouses, and a bakehouse were completed. In 1787, the rebuilt fort became known as Tête-de-Pont Barracks.  During the War of 1812, the fort was the focus of military activity in Kingston, having housed many military troops. Many of the present barrack buildings were built between 1821 and 1824.

HGow many people rebuilt the fort?
