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.

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


[Q]: Passage: Greece has universal health care. In a 2000 World Health Organization report, its health care system ranked 14th in overall performance of 191 countries surveyed. In a 2013 Save the Children report, Greece was ranked the 19th best country (out of 176 countries surveyed) for the state of mothers and newborn babies. In 2010, there were 138 hospitals with 31,000 beds in the country, but on 1 July 2011, the Ministry for Health and Social Solidarity (Greece) announced its plans to decrease the number to 77 hospitals with 36,035 beds, as a necessary reform to reduce expenses and further enhance healthcare standards. Greeces healthcare expenditures as a percentage of GDP were 9.6% in 2007 according to a 2011 OECD report, just above the OECD average of 9.5%. The country has the largest number of doctors-to-population ratio of any OECD country.
[A]: How many countries ranked better than Greece according to the Save the Children report?


[Q]: Passage: After the defeat of several Song armies in the north, Emperor Qinzong wanted to negotiate a truce with the Jin, but he committed a massive strategic blunder when he commanded his remaining armies to protect prefectural cities instead of Kaifeng. Neglecting the importance of the capital, he left Kaifeng defended with fewer than 100,000 soldiers. The Song forces were dispersed throughout China, powerless to stop the second Jurchen siege of the city. The Jin assault commenced in mid December 1126. Even as fighting raged on, Qinzong continued to sue for peace, but Jin demands for territory were enormous: they wanted all provinces north of the Yellow River. After more than twenty days of heavy combat against the besieging forces, Song defenses were decimated and the morale of Song soldiers was on the decline. On January 9, 1127, the Jurchens broke through and started to loot the conquered city. Emperor Qinzong tried to appease the victors by offering the remaining wealth of the capital. The royal treasury was emptied and the belongings of the city's residents were seized. The Song emperor offered his unconditional surrender a few days later. Qinzong, the former emperor Huizong, and members of the Song court were captured by the Jurchens as hostages. They were taken north to Huining , where they were stripped of their royal privileges and reduced to commoners. The former emperors were humiliated by their captors. They were mocked with disparaging titles like "Muddled Virtue" and "Double Muddled". In 1128 the Jin made them perform a ritual meant for war criminals. The harsh treatment of the Song royalty softened after the death of Huizong in 1135. Titles were granted to the deceased monarch, and his son Qinzong was promoted to Duke, a position with a salary.
[A]:
How many months passed between the beginning of the Jin assault on Kaifeng and conquering and looting it?
