instruction:
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.
question:
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 Rügen had to recognise Danish suzerainty. On their accession to power, the Rügen 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 Rügen 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 Rügen'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 Rügen 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 Rügen, 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 Rügen. 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 Rügen fiefdom.
answer:
How many Danish leaders led the conquest at the temple fort?


question:
Passage: In the first four years of the Chávez presidency, the economy grew at first (1999–2001), then contracted from 2001–2003 to GDP levels similar to 1997. At first, the economic decline was due to low oil prices, but it was fueled by the turmoil of the 2002 Venezuelan coup détat attempt and the Venezuelan general strike of 2002–03. Other factors of the decline were an exodus of capital from the country and a reluctance of foreign investors. GDP was 50.0 trillion bolivares in 1998. At the bottom of the recession in 2003, it was 42.4 trillion bolivares (in constant 1998 bolivares). However, GDP rebounded 50.1 trillion bolivares with a calmer political situation in 2004 and rose to 66.1 trillion bolivares in 2007 (both in constant 1998 bolivares).
answer:
Was the GDP larger in 1998 or in 2003?


question:
Passage: The ages of New Havens residents are 25.4% under the age of 18, 16.4% from 18 to 24, 31.2% from 25 to 44, 16.7% from 45 to 64, and 10.2% who were 65 years of age or older. The median age is 29 years, which is significantly lower than the national average. There are 91.8 males per 100 females. For every 100 females age 18 and over, there are 87.6 males.
