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 Vikings' second preseason game took them to San Francisco to take on the 49ers. The game marked the return of quarterback Brett Favre to the Vikings' starting lineup, but he lasted just four plays; the first was a 13-yard pass to RB Adrian Peterson for a first down, but he was sacked for a loss of 10 yards two plays later and was replaced by Tarvaris Jackson for the Vikings' next drive. By the time Favre took the field, the 49ers were already leading 7-0 via a 4-yard run from Anthony Dixon. It was not until the 2nd quarter that the Vikings got their first points on the board, with Ryan Longwell landing a 40-yard field goal. San Francisco responded with two Joe Nedney field goals in the second half before the Vikings' rookie QB Joe Webb took advantage of a gap in the 49ers defense to rush 48 yards for a touchdown, bringing Minnesota within three points with two minutes left to play. Kicker Rhys Lloyd attempted an onside kick, but it was recovered by San Francisco, and by the time the Vikings got the ball back they were on their own 8-yard line with 9 seconds left in the game. They attempted to go for the win, but Webb was sacked in the end zone for a safety as the clock ran out, giving the 49ers a 15-10 win.
Example Output: How many field goals were made?

Example Input: Passage: In the 1985 NFL Draft, the team received the 28th overall pick after winning the Super bowl the previous year. On draft day, the 49ers traded its first two picks for New Englands first-round choice, the 16th selection overall (the teams also swapped third-round picks as part of the deal), and selected Jerry Rice from Mississippi Valley State University. It was reported that the Dallas Cowboys, who had the 17th selection overall, were intending to pick him. In the 1985 season, the 49ers were not as dominant as in 1984, finishing the regular season with a 10–6 record and a wild card berth. Jerry Rice struggled at times (dropping numerous passes), but he still impressed the NFL in his rookie season for the 49ers in 1985, especially after a 10-catch, 241-yard game against the Los Angeles Rams in December. Rice was named NFC Offensive Rookie of the Year after recording 49 catches for 927 yards, and averaging 19.9 yards per catch, Roger Craig (American football) became the first NFL player to gain 1,000 yards rushing and 1,000 yards receiving in the same season. In the 1985 playoffs the 49ers were quickly eliminated from the playoffs by the New York Giants 17–3.
Example Output: How many more points did the New York Giants win by against the 49ers?

Example Input: Passage: In the 1850s, the infant mortality rate in the United States was estimated at 216.8 per 1,000 babies born for whites and 340.0 per 1,000 for African Americans, but rates have significantly declined in the West in modern times. This declining rate has been mainly due to modern improvements in basic health care, technology, and medical advances. In the last century, the infant mortality rate has decreased by 93%. Overall, the rates have decreased drastically from 20 deaths in 1970 to 6.9 deaths in 2003 (per every 1000 live births). In 2003, the leading causes of infant mortality in the United States were congenital anomalies, disorders related to immaturity, SIDS, and maternal complications. Babies born with low birth weight increased to 8.1% while cigarette smoking during pregnancy declined to 10.2%. This reflected the amount of low birth weights concluding that 12.4% of births from smokers were low birth weights compared with 7.7% of such births from non-smokers. According to the New York Times, "the main reason for the high rate is preterm delivery, and there was a 10% increase in such births from 2000 to 2006."  Between 2007 and 2011, however, the preterm birth rate has decreased every year.  In 2011 there was a 11.73% rate of babies born before the 37th week of gestation, down from a high of 12.80% in 2006.
Example Output:
How many fewer babies died per 1000 in 2003 than in 1970?
