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.

Example Input: Passage: The Steelers' last game in the 3-game home stand was against the Browns.  Landry Jones started the game but left due to injury and was replaced by Ben Roethlisberger.  In the first quarter, the Steelers grabbed an early lead as Chris Boswell nailed a 24-yard field goal for a 3-0 lead.  The Browns tied it up however at 3-3 when Travis Coons kicked a 23-yard field goal.  The Steelers would retake the lead later on in the quarter when Boswell nailed a 34-yard field goal for a 6-3 game.  In the second quarter, it was all Steelers when Roethlisberger found Antonio Brown on a 4-yard pass (with a successful 2-point conversion) for a 14-3 lead followed up by Roethlisberger finding Martavis Bryant on a 32-yard pass for a 21-3 lead at halftime.  In the third quarter, the Steelers went back to work as Boswell kicked a 25-yard field goal for a 24-3 game for the only score of the period.  In the fourth quarter, Johnny Manziel found Gary Barnidge on a 7-yard pass (with a failed PAT) for a 24-9 game.  The Steelers later on would wrap the game up when Roethlisberger and Brown hooked up again this time on a 56-yard pass (with a failed PAT) for the final score of 30-9. With the win, the Steelers head into their bye week at 6-4, and finally won a game within their division while also winning consecutive conference games for the first time in the season.  The team also improves to 3-2 when Ben doesn't start and also finishes 2-1 in the 3-game home stand. The defense also stood out by sacking Manziel 6 times and got 3 turnovers.
Example Output: How many field goals were kicked in the first quarter?

Example Input: Passage: The Jurchens were a Tungusic-speaking group of semi-agrarian tribes inhabiting areas of northeast Asia that are now part of Northeast China. Many of the Jurchen tribes were vassals of the Liao dynasty , an empire ruled by the nomadic Khitans that included most of modern Mongolia, a portion of North China, Northeast China, northern Korea, and parts of the Russian Far East. To the south of the Liao lay the Han Chinese Song Empire . The Song and Liao were at peace, but since a military defeat to the Liao in 1005, the Song paid its northern neighbor an annual indemnity of 200,000 bolts of silk and 100,000 ounces of silver. In 1114, the chieftain Wanyan Aguda  united the disparate Jurchen tribes and led a revolt against the Liao. In 1115 he named himself emperor of the Jin "golden" dynasty . Informed by a Liao defector of the success of the Jurchen uprising, the Song emperor Huizong  and his highest military commander the eunuch Tong Guan saw the Liao weakness as an opportunity to recover the Sixteen Prefectures, a line of fortified cities and passes that the Liao had annexed from the Shatuo Turk Later Jin in 938, and that the Song had repeatedly but unsuccessfully tried to reconquer. The Song thus sought an alliance with the Jin against their common enemy the Liao.
Example Output: How many areas did the Khitans rule over?

Example Input: Passage: Substantial increases were made in social security benefits such as injury and sickness benefits, pensions, unemployment benefits, housing allowances, basic subsistence aid allowances, and family allowances and living allowances. In the governments first budget, sickness benefits were increased by 9.3%, pensions for war widows by 25%, pensions for the war wounded by 16%, and retirement pensions by 5%. Numerically, pensions went up by 6.4% (1970), 5.5% (1971), 9.5% (1972), 11.4% (1973), and 11.2% (1974). Adjusted for changes in the annual price index, pensions went up in real terms by 3.1% (1970), 0.3% (1971), 3.9% (1972), 4.4% (1973), and 4.2% (1974). Between 1972 and 1974, the purchasing power of pensioners went up by 19%. In 1970, war pensions were increased by 16%. War victim’s pensions went up by 5.5% in January 1971, and by 6.3% in January 1972. By 1972, war pensions for orphans and parents had gone up by around 40%, and for widows by around 50%. Between 1970 and 1972, the “Landabgaberente” (land transfer pension) went up by 55%. Between 1969 and 1974, the average real standard rate of income support rose (in 1991 prices) from around 300 DM to around 400 DM. Between 1970 and 1974, unemployment benefits rose from around 300 euros to around 400 euros per month, and unemployment assistance from just under 200 euros per month to just under 400 euros per month. In 2001 prices, the average standard social assistance benefit level rose from around 200 euros per month in 1969 to over 250 euros per month in 1974. During most of Brandt’s years as chancellor, the majority of benefits increased as a percentage of average net earnings.
Example Output:
Between how many years did the average real standard rate of income support from 300 DM to around 400 DM?
