TASK DEFINITION: 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.
PROBLEM: 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.

SOLUTION: How many more square miles was the city after its expansion?

PROBLEM: Passage: 2010  The 2010 off-season would bring a surprise when on April 4, Eagles QB Donovan McNabb forced his team to trade him to the Redskins and was also marred by contract disputes with Albert Haynesworth. Washington continued an old tradition of playing its arch-rival Cowboys in the first week of the season. Both teams were unimpressive and the Redskins offense sputtered throughout the game, but they finally won 13-10 after a touchdown pass by Tony Romo was nullified after a holding call. They hosted the Texans in Week 2, but good all-around offensive performance (especially by McNabb, who passed for 426 yards and a touchdown) failed to secure a win. The game tied at 27-27 and went into overtime where Houston kicker Neil Rackers made a 37-yard FG, ending the match at 30-27. After this, the Redskins lost to St. Louis 30-16 before McNabbs return to Philadelphia. Although Washington did not deliver a particularly strong performance, they won 16-12 after Eagles QB Michael Vick was injured and replaced by Kevin Kolb. In Week 5, they hosted Green Bay for only the second time since 1979 (the first was in 2004) and beat them 16-13. After losing a Sunday Night match to the Colts, Washington beat Chicago in Week 7. Although McNabb threw two interceptions, the team took advantage of their opponents porous O-line to sack and pick off Jay Cutler (American football) four times, winning 17-14. After losing a 37-25 trap game in Detroit, the Redskins went on their bye week and returned to host Philadelphia on MNF for the second straight year. As rain fell on Fedex Field, the Eagles proceeded to crush Washington 59-28 with eight touchdowns. In contrast to the huge numbers put up by Michael Vick, McNabb looked decidedly unimpressive, with two touchdown passes and three interceptions (one returned for a TD). Just before the game, he had finalized his contract with the Redskins, who gave him a 5-year, $78 million deal and allowing him to (barring unforeseen circumstances) finish out his career in Washington. After beating Tennessee, the Redskins lost four straight games and were removed from playoff contention before beating Jacksonville in Week 16. After losing to New York at home, the Redskins finished the year at 6-10 and once again 4th place in the division.

SOLUTION: Against which teams did Washington score 16 points?

PROBLEM: Passage: In September 1190 Richard and Philip arrived in Sicily. After the death of King William II of Sicily his cousin Tancred had seized power and had been crowned early in 1190 as King Tancred of Sicily, although the legal heir was William's aunt Constance, wife of the new Emperor Henry VI. Tancred had imprisoned William's widow, Queen Joan, who was Richard's sister and did not give her the money she had inherited in William's will. When Richard arrived he demanded that his sister be released and given her inheritance; she was freed on 28 September, but without the inheritance. The presence of foreign troops also caused unrest: in October, the people of Messina revolted, demanding that the foreigners leave. Richard attacked Messina, capturing it on 4 October 1190. After looting and burning the city Richard established his base there, but this created tension between Richard and Philip Augustus. He remained there until Tancred finally agreed to sign a treaty on 4 March 1191. The treaty was signed by Richard, Philip, and Tancred. Its main terms were:.

SOLUTION:
How many days after freeing his sister did Richard attack Messina and capture it?
