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 Q]: 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.
[EX A]: For how many decades was Germany building up a miltary and intelligence network in Hispaniola?

[EX Q]: Passage: The road building programme was also expanded, with capital expenditure increased to 8% of GDP, "the highest level achieved by any post-war government". Central government expenditure on roads went up from £125 million in 1963/64 to £225 million in 1967/68, while a number of road safety regulations were introduced, covering seat belts, lorry driver's hours, car and lorry standards, and an experimental 70 mile per hour speed limit. In Scotland, spending on trunk roads went up from £6.8 million in 1963/64 to £15.5 million in 1966/67, while in Wales, spending on Welsh roads went up from £21.2 million in 1963/64 to £31.4 million in 1966/67.
[EX A]: By how many millions of pounds did the central government expenditure on roads go up between 1963 and 1968?

[EX Q]: Passage: After the defeat at Marignano, the League no longer possessed the ability or the will to continue the war. Francis advanced on Milan, capturing the city on 4 October and removing Sforza from the throne. In December, he met with Leo at Bologna; the pope, who had in the meantime been deserted by the remainder of his Swiss mercenaries, surrendered Parma and Piacenza to Francis and Modena to the Duke of Ferrara. In return, Leo received guarantees of French noninterference in his proposed attack on the Duchy of Urbino. Finally, the Treaty of Noyon, signed by Francis and Charles V in August 1516, recognized French claims to Milan and Spanish claims to Naples, removing Spain from the war. Maximilian held out, making another attempt to invade Lombardy; his army failed to reach Milan before turning back, and by December 1516, he had entered into negotiations with Francis. The resulting Treaty of Brussels not only accepted French occupation of Milan, but also confirmed Venetian claims to the remainder of the Imperial possessions in Lombardy , effectively ending the war with a return to the status quo of 1508. The peace, however, would last only four years; the election of Charles V as Holy Roman Emperor in 1519 caused Francis, who had desired the position for himself, to begin the Italian War of 1521-26. The Italian Wars, thus reignited, would then continue until 1530 without significant interruption.
[EX A]:
How many cities were surrendered to Francis?
