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: As of the census of 2010, there were 47,723 people, 17,816 households, and 11,722 families residing in the city. The population density was 1,754.6/sq mi (677.5/km²).  There were 19,806 housing units at an average density of 749.9 per square mile (289.6/km²).  The racial makeup of the city was 38.32% White (U.S. Census), 57.25% African American (U.S. Census), 1.25% Native American (U.S. Census), 1.85% Asian, 0.14% Pacific Islander (U.S. Census), 1.03% from Race (United States Census), and 1.09% from two or more races.  6.98% of the population were Hispanics in the United States or Latino (U.S. Census) of any race.
[EX A]: How many fewer households were there compared to housing units?

[EX Q]: 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.
[EX A]: How many more square miles was the city after its expansion?

[EX Q]: Passage: The Qing forces were initially defeated by Wu in 1673-1674. Manchu Generals and Bannermen were put to shame by the performance of the Han Chinese Green Standard Army, who fought better than them against the rebels. The Qing had the support of the majority of Han Chinese soldiers and the Han elite, as they did not join the Three Feudatories. Different sources offer different account of the Han and Manchu forces deployed against the rebels. According to one, 400,000 Green Standard Army soldiers and 150,000 Bannermen served on the Qing side during the war. according to another, 213 Han Chinese Banner companies, and 527 companies of Mongol and Manchu Banners were mobilized by the Qing. According to a third, mustered the Qing a massive army of more than 900,000 Han Chinese to fight the Three Feudatories. Fighting in northwestern China against Wang Fuchen, the Qing put Bannermen in the rear as reserves while they used Han Chinese Green Standard Army soldiers and Han Chinese Generals like Zhang Liangdong, Wang Jinbao, and Zhang Yong as their main military force. The Qing thought that Han Chinese soldiers were superior at fighting other Han people and so used the Green Standard Army as their main army against the rebels instead of Bannermen. As a result, after 1676, the tide turned in favor of the Qing forces. In the northwest, Wang Fuchen surrendered after a three-year-long stalemate, while Geng Jingzhong and Shang Zhixin surrendered in turn as their forces weakened.
[EX A]:
How many more Green Standard Army soldiers served on the Qing side during the war compared to Bannermen?
