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

[EX Q]: Passage: Estimates for the total number of casualties in the war vary, because many deaths went unrecorded. Most suggest that some 60 million people died in the war, including about 20 million military personnel and 40 million civilians.Many of the civilians died because of deliberate genocide, massacres, mass-bombings, disease, and starvation. The Soviet Union lost around 27 million people during the war, including 8.7 million military and 19 million civilian deaths. A quarter of the people in the Soviet Union were wounded or killed. Germany sustained 5.3 million military losses, mostly on the Eastern Front and during the final battles in Germany. Of the total number of deaths in World War II, approximately 85 per cent—mostly Soviet and Chinese—were on the Allied side. Many of these deaths were caused by war crimes committed by German and Japanese forces in occupied territories. An estimated 11 to 17 million civilians died as a direct or as an indirect result of Nazi racist policies, including the Holocaust of around 6 million Jews, half of whom were Polish citizens, along with at least 1.9 million ethnic Poles. Millions of other Slavs , Roma, homosexuals, and other ethnic and minority groups were also killed. Between 1941 and 1945, over 200,000 ethnic Serbs, along with gypsies and Jews, were persecuted and murdered by the Axis-aligned Croatian Ustaše in Yugoslavia. Also, over 100,000 Poles were massacred by the Ukrainian Insurgent Army in the Volhynia massacres, between 1943 and 1945.
[EX A]: Approximately how many Soviet civilians die in the war?

[EX Q]: Passage: Coming off their AFC West division-clinching win over the Chargers, the Broncos traveled to Paul Brown Stadium for an AFC duel against the Cincinnati Bengals on Monday Night Football. The Broncos grabbed the early lead, with cornerback Aqib Talib returning an interception off Bengals' cornerback Andy Dalton 33 yards for a touchdown. However, on the first play of the Bengals' third possession, running back Jeremy Hill reeled off an 85-yard touchdown run to tie the score. The Bengals claimed the lead in the second quarter, with a 37-yard field goal by placekicker Mike Nugent. On the Broncos' next possession, quarterback Peyton Manning was intercepted by Bengals' safety Reggie Nelson, and the Bengals capitalized, with Dalton connecting on a 2-yard touchdown pass to wide receiver Jermaine Gresham. A 49-yard field goal by Nugent with one minute remaining in the first half increased the Bengals' lead to 20-7. The Broncos had one last possession before halftime, however, placekicker Connor Barth missed on a 49-yard field goal attempt. On the Broncos' initial possession of the second half, return specialist Omar Bolden returned the opening kickoff to the Bengals' 21-yard line. Four plays later, running back C. J. Anderson scored on a 1-yard touchdown run. However, the Bengals had a response, as Adam Jones advanced the ensuing kickoff to the Broncos' 27-yard line. Three plays later, Dalton threw a 22-yard touchdown pass to wide receiver Giovani Bernard. The Broncos then scored 14 unanswered points, with Manning throwing a pair of touchdown passes to wide receiver Emmanuel Sanders &#8212; from 4 and 5 yards out &#8212; to give the Broncos a 28-27 lead. The second scoring play came after Broncos' linebacker Von Miller forced a fumble off Hill just as the Bengals were attempting to add to their lead. Rain started to fall in the fourth quarter, and on the Broncos' first fourth quarter possession, Manning was intercepted by Jones deep in Broncos' territory, however, a 15-yard taunting penalty on Nelson pushed the Bengals out of field goal range. The Broncos were forced to punt on their next possession, and return specialist Brandon Tate advanced all the way to the Broncos' 9-yard line. The Broncos defense forced the Bengals to settle for a 23-yard field goal by Nugent to give the Bengals a 30-28 lead with 7:53 remaining in the game. The two teams traded punts on their next possessions, and the Broncos attempted a rally, however, Bengals' cornerback Dre Kirkpatrick returned an interception off Manning 30 yards for a touchdown. With the rain intensifying, the Broncos had one last possession, but Manning threw another interception to Kirkpatrick, this one deep in Bengals' territory &#8212; Manning's fourth interception of the game &#8212; to seal the victory for the Bengals. This was Peyton Manning's first loss to the Bengals in nine career games.
