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.

Passage: Having lost Matt Cassel for the season, the Vikings gave Teddy Bridgewater his first career start at home to the Falcons in week 4, but it was running back Matt Asiata who opened the scoring with a 3-yard touchdown run. Roddy White leveled the scores with a 24-yard catch from Matt Ryan, but a 49-yard kickoff return from Cordarrelle Patterson set the Vikings up with a short field on the next drive, which Asiata finished with a 6-yard run to restore Minnesota's seven-point lead. Steven Jackson thought he had tied the scores again on a 3-yard run with six minutes to go in the half, only for the touchdown call to be overturned on review; however, Ryan was able to find FB Patrick DiMarco in the flat on the next play. However, Bridgewater himself restored Minnesota's advantage on the ensuing possession, capping an 80-yard drive with a 13-yard touchdown run as the game entered its first two-minute warning. After forcing Atlanta into a quick three-and-out, Bridgewater led the Vikings downfield to the brink of another touchdown, but a lack of time meant they had to settle for an 18-yard Blair Walsh field goal to give them a 24-14 lead at the half. Walsh scored another field goal on the opening drive of the second half, but long touchdowns for Devin Hester and Antone Smith gave the Falcons a one-point lead going into the fourth quarter. Those would prove to be Atlanta's last points of the game as Asiata picked up his third TD run early in the fourth quarter, with Bridgewater adding two points with a pass to Rhett Ellison. Bridgewater was injured on that drive, meaning that third-string QB Christian Ponder came in for his first appearance of the season. However, his job was simply to hand the ball off to rookie running back Jerick McKinnon, who set up a 55-yard field goal attempt for Walsh. An interception by Harrison Smith led to another field goal from 33 yards, before Josh Robinson closed the game out with another interception.
How many field goals did Blair Walsh kick?

Passage: The Browns hosted the Pittsburgh Steelers, who were coming off a loss against the Cowboys. The Steelers defeated the Browns 24-9, dropping the Browns to 0-11. With the loss, the Browns were mathematically eliminated from postseason contention for the 14th consecutive season. For the second consecutive season, they were the first NFL team to be mathematically eliminated from contention. The Browns have now gone 24 consecutive seasons without winning a division title, extending the longest active streak in the NFL. They also extended their current franchise record for most consecutive games lost to 14 games. The team is also the first team to start 0-11 since the 2011 Indianapolis Colts.
How many points did the Browns lose by?

Passage: Production of tobacco leaf increased by 40% between 1971, when 4.2 million tons of leaf were produced, and 1997, when 5.9 million tons of leaf were produced. According to the Food and Agriculture organization of the UN, tobacco leaf production was expected to hit 7.1 million tons by 2010. This number is a bit lower than the record-high production of 1992, when 7.5 million tons of leaf were produced. The production growth was almost entirely due to increased productivity by developing nations, where production increased by 128%. During that same time, production in developed countries actually decreased. Chinas increase in tobacco production was the single biggest factor in the increase in world production. Chinas share of the world market increased from 17% in 1971 to 47% in 1997. This growth can be partially explained by the existence of a high import tariff on foreign tobacco entering China. While this tariff has been reduced from 64% in 1999 to 10% in 2004, it still has led to local, Chinese cigarettes being preferred over foreign cigarettes because of their lower cost.

How many more million tons of tobacco leaf were produced in 1997 compared to 1971?
