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: Following the conquest of the temple fort , later known as Jaromarsburg, on Arkona in 1168 by the Danes under King Valdemar I and Bishop Absalon of Roeskilde, the princes of Rugen had to recognise Danish suzerainty. On their accession to power, the Rugen princes were forced to confirm their allegiance to the Danish king and were obliged to provide military support to the Danes. In 1304 Vitslav III of Rugen gained sole lordship over the territory on the death of his brother, Sambor. Because he had no issue at that point in time, there existed the possibility that Rugen's princely house could become extinct. As a result, in 1310 he agreed a contract of inheritance at Ribnitz with the Danish king, Eric VI Menved, his feudal lord. The agreement was that in the event of Vitslav dying without issue, the fiefdom of Rugen would be returned to the Danish crown. At that time, Eric VI Menved was attempting to extend his power in the southern Baltic Sea region in order to reduce the influence of Hanseatic towns like Stralsund. To assist him, in addition to the princes of Rugen, the king also had Prince Henry II of Mecklenburg as a vassal. After the death of Eric VI Menved in 1319, the 1310 treaty lapsed and Vitslav III sought allies in the Pomeranian dukes. On 5 May 1321 dukes Otto I of Pomerania, Vartislav IV of Pomerania-Wolgast and Barnim II of Pomerania-Stettin agreed a mutual inheritance contract with Vitslav III of Rugen. But in an alliance agreement that had been previously concluded on 25 October 1315 between Vartislav IV, the son of Vitslav's sister, Margaret, and Eric's brother, Christopher of Halland, who later became King Christopher II of Denmark, Vartislav IV had already been promised the Rugen fiefdom.

SOLUTION: How many Danish leaders led the conquest at the temple fort?

PROBLEM: Passage: AH-1 Cobras were in use by the Army during the Tet offensive in 1968 and through to the end of the Vietnam War. Cobras provided fire support for ground forces, escorted transport helicopters and other roles, including aerial rocket artillery (ARA) battalions in the two Airmobile divisions. They also formed "hunter killer" teams by pairing with OH-6 Cayuse scout helicopters. A team featured one OH-6 flying slow and low to find enemy forces. If the OH-6 drew fire, the Cobra could strike at the then revealed enemy. On 12 September 1968, Capt. Ronald Fogleman was flying an F-100 Super Sabre when the aircraft was shot down and he ejected 200 miles north of Bien Hoa. Fogleman became the only pilot to be rescued by holding on to an Army AH-1Gs deployed gun-panel door. Bell built 1,116 AH-1Gs for the U.S. Army between 1967 and 1973, and the Cobras chalked up over a million operational hours in Vietnam; the number of Cobras in service peaked at 1,081. Out of nearly 1,110 AH-1s delivered from 1967 to 1973 approximately 300 were lost to combat and accidents during the war. The U.S. Marine Corps used AH-1G Cobras in Vietnam for a short time before acquiring twin-engine Bell AH-1 SuperCobra.

SOLUTION: Approximately how many of the 1110 AH-1s delivered from 1967 to 1973 were lost per year on average?

PROBLEM: Passage: Ethnic Norwegians make up 84.5% of Bergens residents. In addition, 8.1% were Immigrant generations or second generation immigrants of Western background and 7.4% were first or second generation immigrants of non-Western background. The population grew by 4,549 people in 2009, a growth rate of 1,8%. Ninety-six percent of the population lives in urban areas. As of 2002, the average gross income for men above the age of 17 is 426,000 Norwegian krone (NOK), the average gross income for women above the age of 17 is NOK 238,000, with the total average gross income being NOK 330,000. In 2007, there were 104.6 men for every 100 women in the age group of 20-39. 22.8% of the population were under 17 years of age, while 4.5% were 80 and above.

SOLUTION:
How many more NOK was the average gross income for men above the age of 17 compared to women?
