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: 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 over the Chargers the Raiders flew to EverBank Field for an AFC duel with the Jaguars. In the first quarter the Raiders took the lead as QB Jason Campbell completed a 67-yard TD pass to RB Darren McFadden. The Jaguars replied in the second quarter with QB David Garrard making a 1-yard TD pass to TE Marcedes Lewis. They increased their lead as kicker Sebastian Janikowski nailed a 26-yard field goal, followed by Campbell throwing an 8-yard TD pass to WR Louis Murphy. The lead was narrowed as Garrard made a 48-yard TD pass to WR Jason Hill. But the Raiders replied as McFadden ran 51&#160;yards for a touchdown. They fell behind for the first time with RB Rashad Jennings getting a 74-yard TD run, followed by Garrard getting a 10-yard TD pass to WR Mike Sims-Walker, followed by Scobee nailing a 19-yard field goal. Oakland tied the game as McFadden got a 36-yard TD run, but the Jaguars pulled out the win with RB Maurice Jones-Drew getting a 30-yard TD run.
Example Output: How many field goals did each kicker score?

Example Input: Passage: The Chargers defeated the Kansas City Chiefs 37-20 and started the season with a 3-1 record for the second consecutive year.  San Diego forced the Chiefs into six turnovers, and they led 20-0 in the second quarter. Rivers completed 18 of 23 passes for 209 yards and two touchdown passes, but threw one interception in the red zone. Jackie Battle started at running back instead of Mathews. Battle was in 27 plays compared to Mathews' 21, and he had 15 carries for 39 yards with a team-high four catches for 42 yards. Most of Mathews work was in the fourth quarter when San Diego's victory was mostly already decided. U-T San Diego wrote that Mathews would have been expected to start were it not for his fumble against Atlanta the prior week. Nick Novak filled in for kicker Nate Kaeding, who was out with a groin injury, and made all three of his field goals.
Example Output:
By how many points did the Chiefs lose against the Chargers?
