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: The population of the city proper is 370,702, while Eurostat estimates that 696,767 people live in the Larger Urban Zones of Florence. The Metropolitan Area of Florence, Prato and Pistoia, constituted in 2000 over an area of roughly , is home to 1.5 million people. Within Florence proper, 46.8% of the population was male in 2007 and 53.2% were female. Minors (children aged 18 and less) totalled 14.10 percent of the population compared to pensioners, who numbered 25.95 percent. This compares with the Italian average of 18.06 percent (minors) and 19.94 percent (pensioners). The average age of Florence resident is 49 compared to the Italian average of 42. In the five years between 2002 and 2007, the population of Florence grew by 3.22 percent, while Italy as a whole grew by 3.56 percent. The birth rate of Florence is 7.66 births per 1,000 inhabitants compared to the Italian average of 9.45 births.

Output: By how many points lower is Florence's brith rate than that of the Italian average?


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-Haïten 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: Warbeck was initially treated well by Henry. As soon as he confessed to being an impostor, he was released from the Tower of London, and was given accommodation at Henry's court. He was even allowed to be present at royal banquets. He was, however, kept under guard and was not allowed to sleep with his wife, who was living under the protection of the queen. After 18 months at court, Warbeck tried to escape. He was quickly recaptured. He was then held in the Tower, initially in solitary confinement, and later alongside Edward Plantagenet, 17th Earl of Warwick; the two tried to escape in 1499. Captured once again, Warbeck was led from the Tower to Tyburn, London on 23 November 1499, where he read out a confession and was hanged. The Earl of Warwick was beheaded on Tower Hill on 28 November 1499. Warbeck was buried in Austin Friars, London. The presumed site of his unmarked grave still exists as the Dutch Church, Austin Friars.


Output: How many days between Warbeck being hanged and the Earl of Warwick was beheaded?
