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: 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.

SOLUTION: After the Ming navy began trying to stop smuggling in 1543, how many years passed before the Xu syndicate downfall?

PROBLEM: Passage: Needing a win to secure their first playoff berth since 2002, the Browns flew to Paul Brown Stadium for Round 2 of the Battle of Ohio with the Cincinnati Bengals. After a scoreless first quarter, Cleveland trailed in the second quarter as Bengals kicker Shayne Graham nailed a 29-yard and a 38-yard field goal, along with QB Carson Palmer completing a 5-yard TD pass to WR T.J. Houshmandzadeh and RB Kenny Watson getting a 1-yard TD run. In the third quarter, the Browns began to rally as QB Derek Anderson completed a 2-yard TD pass to WR Braylon Edwards for the only score of the period. In the fourth quarter, Cleveland drew closer as Anderson and Edwards hooked up with each other again on a 5-yard TD pass. Late in the game, the Browns tried to take the lead, but Cincinnati's early lead was too much to overcome. Despite the loss, Braylon Edwards set the Browns' single-season record for the most touchdown receptions with 15. Also, with TE Kellen Winslow reaching 1,000 receiving yards for the first time in his career, Edwards & Winslow became the franchise's first receiving duo to get 1,000&#160;yards in the same year.

SOLUTION: How many field goals did Cincinnati have in the second quarter?

PROBLEM: Passage: On 6 and 13 December 1971, the Soviet Navy dispatched two groups of cruisers and destroyers and a submarine armed with nuclear missiles from Vladivostok; they trailed US Task Force 74 into the Indian Ocean from 18 December 1971 until 7 January 1972. The Soviets also had a nuclear submarine to help ward off the threat posed by USS Enterprise task force in the Indian Ocean.

SOLUTION:
For how many days did the Soviet naval groups trail US Task Force 74?
