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: On November 12, the Chiefs traveled to Dolphin Stadium to play the Miami Dolphins.  The Chiefs entered the game with a three-game winning streak and the Dolphins entered with an upset victory over the previously undefeated Chicago Bears.  The game was broadcast on CBS at 1pm Miami time. In a November 7 press conference, Herm Edwards backed off on the subject of whether Trent Green will retain his starting role.  On Election Day, Chiefs' fans were asked to vote for their choice of starting quarterback on The Kansas City Star's website.  Damon Huard won the poll with 58%.  The vote did not determine Edwards' decision, and was strictly for the fan's input. Pro Bowler Brian Waters missed the game and several other Chiefs players&#8212;including Derrick Johnson and Greg Wesley&#8212;missed the game with their own injuries.  Kansas City was 3-for-14 on third-down conversions and had the ball for only 24&#160;minutes throughout the game. The Chiefs were shut out by the end of the first half, the first time Miami had not allowed their opponents to score all season.  After the second half, the Chiefs began to regain their ground.  A fumble by Ronnie Brown gave Kansas City's Jared Allen 20-yards to recover and put the Chiefs in the red zone.  Larry Johnson would finish the opportunity from the turnover and score from 2-yards out for a touchdown.  The Chiefs now trailed 10-13 following an XPA by Lawrence Tynes. The Chiefs regained the ball after a failed offensive drive by Miami with 3:10 left in the game.  A costly sack by former Chiefs player Vonnie Holliday would put Damon Huard back within 5-yards of the end zone.  The Chiefs would not be able to rally back from the 3-point deficit following an incomplete pass to Tony Gonzalez.  The Dolphins ran the clock out for their third win of the season, and Kansas City's first loss in three games as the team fell to 5-4.
[EX A]: How many percent of the vote did Damon Huard not get?
