TASK DEFINITION: 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.
PROBLEM: Passage: Coming off their win over the Titans, the Dolphins stayed at home for a Week 11 interconference duel with the Chicago Bears on Thursday night.  Miami trailed early in the first quarter as Bears kicker Robbie Gould got a 46-yard field goal.  Chicago added onto their lead in the second quarter with Gould making a 24-yard field goal. The Bears continued to increase their lead with Gould's 50-yard field goal, followed by a touchdown scored by running back Matt Fort&#233;. This was the final score of the game, with Chicago's defense preventing any score by the Dolphins.

SOLUTION: How long were each of Robbie Gould's field goals?

PROBLEM: Passage: Hoping to rebound from their road loss to the Steelers, the 49ers went home and played an NFC West battle with the Seattle Seahawks. In the first quarter, the Niners lost QB Alex Smith with a separated shoulder during a sack.  Back-up QB Trent Dilfer would take the position for the rest of the game. In the second quarter, San Francisco's recent woes continued with Seahawks kicker Josh Brown getting a 23-yard field goal. Afterwards, Seattle began to pound away with QB Matt Hasselbeck completing a 17-yard TD pass to WR Bobby Engram, along with Brown kicking a 31-yard field goal. In the third quarter, the Seahawks continued their domination as Hasselbeck completed a 14-yard TD pass to TE Marcus Pollard. The Niners would get their only score of the game as kicker Joe Nedney got a 43-yard field goal. In the fourth quarter, Seattle sealed San Francisco's doom with Brown nailing a 25-yard field goal.

SOLUTION: How many field goals between 20 and 30 yards were scored?

PROBLEM: Passage: The state of Kampuchea , officially Democratic Kampuchea , existed between 1975 and 1979 in present-day Cambodia. The state was controlled by the Khmer Rouge  and was founded when KR forces defeated the Khmer Republic of Lon Nol in 1975. Between 1975 and 1979, the state and its ruling Khmer Rouge regime was responsible for the deaths of millions of Cambodians through forced labour and genocide. The KR lost control of most Cambodian territory to Vietnamese occupation. From 1979 to 1982 Democratic Kampuchea survived as a rump state supported by China. In June 1982, the Khmer Rouge formed the Coalition Government of Democratic Kampuchea with two non-communist guerilla factions, which retained international recognition. The state was renamed Cambodia in 1990 in the run up to the UN-sponsored Paris Peace Agreement conference of 1991.

SOLUTION:
About how many years did the state of Kampuchea exist for?
