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.

Example Input: Passage: In 1950, Sultan Omar Ali Saifuddien III, upon his ascension to the throne, negotiated with the British for an increase in corporate taxes, growing from 10% to 30% in 1953. A Malayan dollar$1.2 million (US$0.39 million) allotment to Brunei for war damages during the Japanese occupation of British Borneo increased from M$1 million in 1946 to M$100 million (US$32.6 million) in 1952. A five-year development plan with a budget of M$100 million was also implemented in 1953, with infrastructure receiving the largest percentage (80%) and the rest going toward social programmes. Together with the expansion of the oil and gas industry, commercialisation began to transform Bruneis capital and a large number of public buildings were constructed, along with the development of a central business district in the 1970s and 1980s. On 1 August 2007, Sultan Hassanal Bolkiah gave consent for the expansion of the city from 4.97 sq mi to 38.75 sq mi.
Example Output: How many more square miles was the city after its expansion?

Example Input: Passage: Coming off their home win over the Browns, the Cardinals flew to Qwest Field for a Week 14 NFC West rematch with the Seattle Seahawks.  In the first quarter, Arizona trailed early as Seahawks kicker Josh Brown managed to get a 23-yard field goal, along with QB Matt Hasselbeck completing a 7-yard TD pass to WR Nate Burleson.  In the second quarter, the Cards continued to trail as Hasselbeck completed a 15-yard TD pass to WR Bobby Engram and a 17-yard TD pass to WR Deion Branch.  The Cardinals would get on the board as QB Kurt Warner completed a 5-yard TD pass to WR Bryant Johnson, yet Seattle increased their lead prior to halftime with Brown kicking a 41-yard field goal. In the third quarter, the Cards tried to rally as Warner completed a 2-yard TD pass to WR Jerheme Urban for the only score of the period.  However, in the fourth quarter, the Seahawks pulled away as Hasselbeck completed a 3-yard TD pass to TE Marcus Pollard, RB Josh Scobey tackling Cardinals punter Mitch Berger in the end zone for a safety, and CB Marcus Trufant returning an interception 84 yards for a touchdown (with a failed PAT).  Arizona tried to come back as Warner completed an 11-yard TD pass to WR Larry Fitzgerald.  However, Seattle's defense was too much to overcome.
Example Output: How many points did the Seahawks score in the first quarter?

Example Input: Passage: The site of the current bridge is among several sites of a slave rebellion called the Stono Rebellion, one of the earliest known organized acts against slavery in the Americas.  On September 9, 1739, twenty black slaves raided a store near the bridge; in the process they killed two storekeepers and took guns and gunpowder. The bridge survived an attempt by Union forces to burn it during the American Civil War. Union troops floated burning rafts down to the Stono Bridge, hoping the wooden structure would catch fire and burn. However, their efforts were thwarted by a Lieutenant Smith, who along with members of a naval battalion, brought the rafts to shore. There have been several bridges in this location; the last variation was a two lane bridge 1,416 feet -long, which was built in 1928, and later refurbished in 1950. This swing-span drawbridge used a 156-foot -long steel-truss which left little room for even small vessels to pass beneath unless it was open.
Example Output:
How many feet shorter was the steel-truss on the bridge than the length of the bridge?
