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 season-sweep over the Ravens, the Bengals went home a Week 11 interconference duel with the Arizona Cardinals. In the first quarter, Cincinnati struck first with QB Carson Palmer completing a 19-yard TD pass to WR T.J. Houshmandzadeh. The Cardinals would answer with CB Antrel Rolle returning an interception 55 yards for a touchdown. In the second quarter, the Bengals regained the lead with kicker Shayne Graham getting a 41-yard field goal. However, Arizona took the lead with QB Kurt Warner completing a 44-yard TD pass to WR Anquan Boldin. Cincinnati responded with Graham kicking a 38-yard field goal, but the Cardinals increased their lead with Warner completing a 5-yard TD pass to WR Larry Fitzgerald. In the third quarter, the Bengals trailed as RB Edgerrin James gave Arizona a 3-yard TD run. Cincinnati tried to rally as Palmer completed a 37-yard TD pass to WR Chris Henry, while RB DeDe Dorsey returned a blocked punt 19 yards for a touchdown. The Cardinals sealed the win with Rolle returning an interception 54 yards for a touchdown.

SOLUTION: How long were Shayne Graham's made field goals?

PROBLEM: Passage: The index reached a relative intraday high—which was not exceeded for over seven years—of 1,552.87, on March 24, 2000, during the dot-com bubble. The index then declined by approximately 50%, to 768.63, on October 10, 2002, during the stock market downturn of 2002. On May 30, 2007, the S&P 500 closed at 1,530.23, to set its first all-time closing high in more than seven years. Although the index achieved a new all-time intraday high on October 11, 2007, at 1,576.09, following a record close of 1,565.15 on October 9, the index finished 2007 at 1,468.36 points—just below its 1999 annual close. Less than a month later, it dropped to 1,400, and would not see similar levels again for five years.

SOLUTION: How many points had the index gained from October 10, 2002 to October 11, 2007?

PROBLEM: Passage: Nigerias population has been increasing rapidly for at least the last 5 decades due to very high birth rates, quadrupling its population during this time. That type of growth rate is known as exponential. It is not growing at a linear rate. Growth was fastest in the 1980s, after child mortality had dropped rapidly, and has slowed slightly since then as the birth rate has declined slightly. According to the 2017 revision of the World Population Prospects the total population was 185,989,640 in 2016, compared to only 37,860,000 in 1950. The proportion of children under the age of 15 in 2010 was 44.0%, 53.2% was between 15 and 65 years of age, while 2.7% was 65 years or older. There is a large Population momentum, with 3.2 percent growth rate leading to the projected population.

SOLUTION:
How many more people populated the country in 2016 than in 1950?
