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.

Q: 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.

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

New York answered with a 34-yard field goal from John Carney. As New York tried to get a drive going they contended with the a Dallas defence that leads the league in sacks.  Quarterback Eli Manning was brought down eight times during the game.  In the fourth quarter Dallas extended its small lead with a 1-yard touchdown pass to full back Deon Anderson.  After a mistake by the Dallas offensive line the Giants scored a safety.  Later John Carney nailed a 47-yard field goal to make the score 14-8 for Dallas.  With 2:24 left on the clock Dallas sealed the win with a 38-yard touchdown run by Tashard Choice.  The two-point conversion failed. With the win, Dallas improved to 9-5. This would be the last Cowboys win at Texas Stadium and for the 2008 NFL Season.

A: How many is the difference in the  yards of the pass to Crayton and the yards of the TD run by Choice?

Q: Passage: Superferry 14 was a large ferry destroyed by a bomb on 27 February 2004, killing 116 people in the Philippines' worst terrorist attack and the world's deadliest terrorist attack at sea. On that day, the 10,192 ton ferry sailed out of Manila with about 900 passengers and crew on board. A television set filled with 8 lb.  of TNT had been placed on board. 90 minutes out of port, the bomb exploded. 63 people were killed instantly and 53 were missing and presumed dead. Despite claims from terrorist groups, the blast was initially thought to have been an accident caused by a gas explosion. However, after divers righted the ferry five months after it had sunk, they found evidence of a bomb blast. A man called Redendo Cain Dellosa admitted to planting the bomb for Abu Sayyaf. Six suspects were arrested in connection with the bombing while the masterminds, Khadaffy Janjalani and Abu Sulaiman, were killed.

A:
How many days did the worst terrorist attack and the world's deadliest terrorist attack at sea overlap?
