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.

Input: Consider Input: Passage: The Kaga Rebellion or Chōkyō Uprising was a large-scale revolt in Kaga Province , Japan, in late 1487 through 1488. Togashi Masachika, who ruled Kaga Province as shugo, had been restored to power in 1473 with aid from the Asakura clan as well as the Ikkō-ikki, a loose collection of lesser nobility, monks, and farmers. By 1474, however, the Ikkō-ikki grew discontent with Masachika, and launched some initial revolts, which were easily quelled. In 1487, when Masachika left on a military campaign, between one hundred thousand and two hundred thousand Ikkō-ikki revolted. Masachika returned with his army, but the Ikkō-ikki, backed by several disaffected vassal families, overwhelmed his army and surrounded him in his palace, where he committed seppuku. The former vassals of Masachika granted the position of shugo to Masachika's uncle Yasutaka, but over the next several decades, the Ikkō-ikki increased their political hold on the province, which they would effectively control for almost a century.

Output: How many decades passed when Ikkō-ikki increased their political hold on the province?


Input: Consider Input: Passage: After securing their first win of the season, the Browns went on the road to take on their archrival Pittsburgh Steelers. The Browns came into the game having lost their last 11 games against the Steelers. The Steelers struck first with two touchdown passes from Ben Roethlisberger in the 2nd quarter. Josh Cribbs ran a kickoff back 98 yards for a touchdown, and got the Browns within 7. However, the Browns could never close the gap, and fell to the Steelers, 27-14.

Output: How many games have the Browns won this season?


Input: Consider Input: Passage: As of 2012, Singapore total fertility rate (TFR) is 1.20 children born per woman, which represents a sub-replacement fertility rate and is one of the lowest in the world. Ethnic Chinese had a ferlility of 1.07 in 2004 (1.65 in 1990), while Malays had a TFR of 2.10 (2.69 in 1990). Both figures declined further in 2006. TFR for Indians was 1.30 in 2004 and 1.89 in 1990.  The Singapore government has launched several highly publicised attempts to raise the fertility rate and increase awareness of the negative effects of an aging population, the elderly (65 and above) had constituted 9.9% of its population in 2012; this proportion is still significantly lower than that of many other developed nations, such as the United States (12%) and Japan (21.2%) .


Output: How many  more percent were not 65 years of age or older in Singapore than in Japan?
