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: Tampa Bay got off to a slow start as Kansas City took the opening drive 69 yards for a touchdown. On Tampa Bay's first play from scrimmage, Earnest Graham fumbled and the Chiefs recovered. The turnover led to another Kansas City touchdown, and a 14-0 lead. Early in the second quarter, Tampa Bay drove into the red zone, and scored a field goal. On the following drive, the Chiefs executed a flea-flicker play and quarterback Tyler Thigpen caught an improbable 37-yard touchdown pass. Late in the second quarter, the Chiefs added a field goal, to stretch the lead to 24-3. On the ensuing kickoff, Clifton Smith scored a 97-yard kickoff return touchdown, the second such in franchise history. The Buccaneer defense held the Chiefs to a 3-and-out, and the offense took over with 1:08 to go. As time expired in the half, Matt Bryant's second field goal trimmed the deficit to 24-13. Neither team scored in the third quarter, and all drives ended in punts. Early in the fourth quarter, Jeff Garcia again drove Tampa Bay into the red zone. Clifton Smith caught a pass, but fumbled at the 13. Kansas City recovered at their own 10. On the very next play, Jamaal Charles fumbled away a pitch in the backfield, and Tampa Bay recovered inside the 3. In a trick play, Jeff Garcia handed off to Earnest Graham, who passed to Alex Smith for a touchdown. A two-point conversion failed, and the score trimmed to 24-19. With 3:34 to go, the Buccaneers drove to the Kansas City 3, and Earnest Graham appeared to be heading for a potential game-tying score. The ball was fumbled, however, and the Chiefs took over on a touchback. The Buccaneer defense forced a punt, and they took over with 1:50 to go. Jeff Garcia quickly drove the Buccaneers to a 25-yard touchdown, and a two-point conversion catch by Alex Smith sent the game to overtime. In the overtime period, Tampa Bay won the coin toss. They drove to the Kansas City 15-yard line, and Matt Bryant won the game on a 34-yard field goal. The victory marked the largest comeback (from 21 points behind to win) in franchise history. With the win, the Buccaneers went into their bye week at 6-3.
[EX A]: How many field goals were there before halftime?

[EX Q]: Passage: Over the centuries, Weimar remained a small town of less than 5,000 inhabitants. When it became the capital of Saxe-Weimar in 1572, population growth was stimulated and population increased from 3,000 in 1650 to 6,000 in 1750. Around the year 1800, Weimar had 7,000 inhabitants. Their number grew constantly over the years to 13,000 in 1850, 28,000 in 1900 and 35,000 at the beginning of World War I. During the interwar period, the new capital of Thuringia saw a population boom, which led to 65,000 inhabitants in 1940. Since that time, the population levels have stagnated. The years 2009 to 2012 brought a moderate growth of approximately 0.35% p. a., whereas the population in bordering rural regions is shrinking with accelerating tendency. Suburbanization played only a small role in Weimar. It occurred after the reunification for a short time in the 1990s, but most of the suburban areas were situated within the administrative city borders.
[EX A]: Between 1750 and 1900, how many residents did Weimar gain?

[EX Q]: Passage: Scandinavians maintained trade relations and other links with Novgorod from the Viking Age onwards. Merchants from Gotland operated both their own trading house  and the St. Olof church in Novgorod. Scandinavians also carried out isolated  raids on Novgorod. Eiríkr Hákonarson raided  Ladoga in 997, and his brother Sveinn Hákonarson followed suit in 1015. After the marriage of Yaroslav I  to Ingegerd of Sweden in 1019, Ladoga became a jarldom in the orbit of Kievan Rus. It was ruled by Ragnvald Ulfsson, the alleged father of King Stenkil of Sweden . Dynastic marriages took place between Russian and Scandinavian royal families - for example, in  the 1090s Stenkil's granddaughter  Christina married Mstislav of Novgorod, upon whose death in 1132 Novgorod seceded from Kievan Rus. The major turning point into more permanent conflict between Sweden and Novgorod arrived with Sweden's firmer organization into the Catholic Church in the 12th century and papal involvement in crusades against lands controlled by the Orthodox Church.
[EX A]:
How many years after Eiríkr Hákonarson raided Ladoga did his brother Sveinn Hákonarson follow suit?
