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.

[EX Q]: Passage: Coming off their dominating road win over the Jaguars, the Eagles went home for their Week 4 NFC East duel with the Washington Redskins, as quarterback Donovan McNabb made his highly anticipated return to Philadelphia. The Eagles trailed in the first quarter as Redskins running back Ryan Torain got a 12-yard touchdown run, followed by McNabb's 31-yard touchdown pass to tight end Chris Cooley.  Philadelphia answered in the second quarter with kicker David Akers making a 49-yard field goal, but Washington came right back with kicker Graham Gano's 26-yard field goal.  Afterwards, the Eagles closed out the half with Akers' 23-yard field goal.  After a scoreless third quarter, Philadelphia tried to rally in the fourth quarter as quarterback Kevin Kolb hooked up with tight end Brent Celek.  However, the Redskins' defense prevented any further progress.
[EX A]: How many field goals did Akers make?

[EX Q]: Passage: The Broncos' defense forced a three-and-out on the Patriots' first offensive drive, however, it was all downhill for the Broncos after that. The Patriots capitalized on four blunders by the Broncos' special teams. First, Isaiah McKenzie muffed a punt, giving the Patriots a short field. Then, Patriots' return specialist Dion Lewis returned a kickoff 103 yards for a touchdown. The Patriots also blocked a punt, and a defensive penalty on a Patriots' punt resulted in a first down as well as another touchdown. Patriots' quarterback Tom Brady threw for 266 yards and three touchdown passes. Offensively, the Broncos had to settle for three Brandon McManus field goals and achieved only one touchdown &#8212; a 7-yard pass from Brock Osweiler to wide receiver Demaryius Thomas.
[EX A]: How many touchdowns did the Broncos score?

[EX Q]: Passage: In 212 BC, the Emperor Qin Shi Huang commanded all books in the Qin Empire other than officially sanctioned ones be burned. This decree was not universally obeyed, but as a consequence of this order little is known about ancient Chinese mathematics before this date. After the Burning of books and burying of scholars of 212 BC, the Han dynasty (202 BC–220 AD) produced works of mathematics which presumably expanded on works that are now lost. The most important of these is The Nine Chapters on the Mathematical Art, the full title of which appeared by AD 179, but existed in part under other titles beforehand. It consists of 246 word problems involving agriculture, business, employment of geometry to figure height spans and dimension ratios for Chinese pagoda towers, engineering, surveying, and includes material on right triangles. It created mathematical proof for the Pythagorean theorem, and a mathematical formula for Gaussian elimination. The treatise also provides values of π, which Chinese mathematicians originally approximated as 3 until Liu Xin (scholar) (d. 23 AD) provided a figure of 3.1457 and subsequently Zhang Heng (78-139) approximated pi as 3.1724, as well as 3.162 by taking the square root of 10. Liu Hui commented on the Nine Chapters in the 3rd century AD and Liu Huis π algorithm accurate to 5 decimal places (i.e. 3.14159). Though more of a matter of computational stamina than theoretical insight, in the 5th century AD Zu Chongzhi computed Milü to seven decimal places (i.e. 3.141592), which remained the most accurate value of π for almost the next 1000 years. He also established a method which would later be called Cavalieris principle to find the volume of a sphere.
[EX A]:
How many people changed the values of pi?
