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.

Input: Consider Input: Passage: Between 1911 and 1915, Haiti was politically unstable: a series of political assassinations and forced exiles resulted in six presidents holding office during this period. Various revolutionary armies carried out the coups. Each was formed by cacos, or peasant militia from the mountains of the north, or who invaded along the porous Dominican border. They were enlisted by rival political factions under the promises of money, which would be paid after a successful revolution, and the opportunity to plunder. The United States was particularly apprehensive about the roles played by Imperial Germany in the Western hemisphere. Controlling Tortuga, it had intervened in Haiti and other Caribbean nations at several times during the previous few decades to exert its influence as a rival power. Germany was increasingly hostile to United States domination of the region under its claimed Monroe Doctrine. In the lead-up to the World War I, the strategic importance of the island of Hispaniola, with its manpower, material wealth, and port facilities, was understood by almost all navies operating in the Caribbean, including Germany and the still-neutral United States. Germany had invested in military and intelligence gathering across Hispaniola as part of a wider network of German interest in Latin America and the Caribbean during the 1890s through the 1910s. The United States' concern over Germany's ambitions was mirrored by apprehension and rivalry between American businessmen and the small German community in Haiti, which although numbering only about 200 in 1910 wielded a disproportionate amount of economic power. German nationals controlled about 80 percent of the country's international commerce. They owned and operated utilities in Cap-Haiten and Port-au-Prince, including the main wharf and a tramway in the capital, and also had built the railway serving the Plain of the Cul-de-Sac.

Output: For how many decades was Germany building up a miltary and intelligence network in Hispaniola?

Input: Consider Input: Passage: With the end of the "crack epidemic" in the mid-1990s and with the initiation of aggressive policing under mayors David Dinkins and subsequently Rudolph Giuliani, crime in Harlem plummeted. In 1981, 6,500 robberies were reported in Harlem; robberies dropped to 4,800 in 1990 during David Dinkins mayoralty. By 2000, only 1,700 robberies were reported, and by 2010, only 1,100 were reported. There have been similar changes in all categories of crimes tracked by the New York City Police Department. In the 32nd Precinct, which services Central Harlem above 127th Street, for example, between 1990 and 2013, the murder rate dropped 89.4%, the rape rate dropped 67.5%, the robbery rate dropped 74.2%, burglary dropped 93.4%, and the total number of crime complaints dropped 77.6%.

Output: How many fewer robberies were reported to the New York City Police Department in 2010 than in 2000?

Input: Consider Input: Passage: Nationalist groups had been angered by the Russification undertaken since Alexander II. The Poles, Finns, and the Baltic provinces all sought autonomy, and also freedom to use their national languages and promote their own culture. Muslim groups were also active, founding the Union of the Muslims of Russia in August 1905. Certain groups took the opportunity to settle differences with each other rather than the government. Some nationalists undertook anti-Jewish pogroms, possibly with government aid, and in total over 3,000 Jews were killed. The number of prisoners throughout the Russian Empire, which had peaked at 116,376 in 1893, fell by over a third to a record low of 75,009 in January 1905, chiefly because of several mass amnesties granted by the Tsar; the historian S G Wheatcroft has wondered what role these released criminals played in the 1905-06 social unrest.
Output: How many fewer Jews were killed than the number of prisoners decrease from 1905 over 1893?
