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.

Example Input: Passage: The Toi invasion  was the invasion of northern Kyūshū by Jurchen pirates in 1019. At the time, Toi  meant "barbarian" in the Korean language. The Toi pirates sailed with about 50 ships from direction of Goryeo, then assaulted Tsushima and Iki, starting 27 March 1019. After the Iki Island garrison comprising 147 soldiers was wiped out, the pirates has proceed to Hakata Bay. For a week, using Noko Island  in the Hakata Bay as a base, they sacked villages and kidnapped over 1,000 Japanese, mostly women and young girls, for use as slaves. The Dazaifu, the administrative center of Kyūshū, then raised an army and successfully drove the pirates away. During the second failed raid to Matsuura 13 April 1019, three enemies were captured by the Japanese army. They were identified as Koreans. They said that they had guarded the borderland but had been captured by the Toi. However, this was unlikely, and the Japanese officers suspected them because there had been Korean pirates attacking Japan coasts during the Silla period. A few months later, the Goryeo delegate Jeong Jaryang  reported that Goryeo forces attacked the pirates off Wŏnsan and rescued about 260 Japanese. The Korean government then repatriated them to Japan where they were thanked by the Dazaifu and given rewards. There remain detailed reports by two captive women, Kura no Iwame and Tajihi no Akomi. These Jurchen pirates lived in what is today Hamgyŏngdo, North Korea.
Example Output: Did the second raid to Matsuura succeed?

Example Input: Passage: After their ouster from the coastal ports of China, Japanese and Portuguese traders collaborated with illegal smugglers on island ports along the Zhejiang and Fujian coast. Among these ports, Shuangyu on Liuheng Island  off the coast of Ningbo emerged as the primary emporium of clandestine trade. At first, Shuangyu only had temporary mat-sheds for the smugglers to house themselves and their goods during the trading season. In 1539, Fujianese traders started to guide foreign traders from Patani and Malacca to barter in Shuangyu and started to occupy the island. They were soon joined by the Fujianese merchants Jinzi Lao  and Li Guangtou , who led the Portuguese and assorted adventurers to Shuangyu. Attracted by the growing trade on the Zhejiang coast, the Xu brothers' syndicate moved their base of operations from the Malay Peninsula to Shuangyu. The existing clout of the Xu syndicate and its close partnership with the Portuguese made it the foremost smuggling bloc by 1542 after a series of mergers among the merchant-pirates in Shuangyu. The Ming navy began to clamp down on smuggling activities in 1543, but the Xu syndicate was able to repulse the Ming attacks in Shuangyu with the aid of Portuguese firepower. Hardened by their victories against the Ming navy, the smugglers expanded their network of activities down the coast of China all the way to Guangdong and inland to the metropolis of Nanjing, with Shuangyu being their hub. In 1544, this network was further expanded when Wang Zhi joined the Xu syndicate, bringing along his Japanese connections to Shuangyu. Thus Shuangyu reached its zenith as the biggest entrepôt in maritime East Asia trading goods from Europe and Asia until its downfall in 1548.
Example Output: After the Ming navy began trying to stop smuggling in 1543, how many years passed before the Xu syndicate downfall?

Example Input: Passage: Coming off their win against the Steelers, the Chiefs went on the road for an AFC West rivalry match against the San Diego Chargers. In the first quarter the Chiefs trailed early as QB Philip Rivers got a 19-yard touchdown pass to TE Antonio Gates. The Chiefs would reply to tie the game with QB Matt Cassel making a 7-yard touchdown pass to WR Chris Chambers, until they fell back again with RB LaDainian Tomlinson getting a 1-yard touchdown run, then Rivers hooking up with Gates again on a 15-yard touchdown pass, then DB Paul Oliver returned a fumble 40 yards for a touchdown. In the third quarter the Chiefs' struggle continued as RB LaDainian Tomlinson got a 3-yard touchdown run. They tried to come back with RB Jamaal Charles getting a 2-yard touchdown run, but the Chargers would pull away with kicker Nate Kaeding making a 55-yard field goal. In the fourth quarter the problem got worse when a penalty on Matt Cassel was enforced in the end zone for a safety, giving the Chargers 2 points. The final score was made when Kaeding booted a 23-yard field goal.
Example Output:
How many of the field goals kicked were over 50 yards?
