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: The Dano-Hanseatic War from 1426-1435  was an armed trade conflict between the Danish dominated Kalmar Union  and the German Hanseatic League  led by the Free City of Lübeck. When Danish king Eric opened the Baltic trade routes for Dutch ships and introduced a new toll for all foreign ships passing the Øresund , six Hanseatic cities  declared war, put a naval blockade on Scandinavian harbours and allied with Eric's enemy Henry IV, count of Holstein. Therefore the war was intensively linked with the Dutch-Hanseatic War , the Kalmar War with Holstein  and the Swedish revolt . After years of changing fortune in warfare Rostock and Stralsund signed a separate peace agreement in 1430. Lübeck, Hamburg, Wismar and Lüneburg, however, continued the war and assisted Holstein to conquer Flensburg in 1431. Thereafter they agreed an armistice in 1432 and started peace negotiations. Meanwhile an anti-Danish revolt broke out in Sweden . In 1434 Eric had to agree an armistice with the Swedes, too. In April 1435 he signed the peace of Vordingborg with the Hanseatic League and Holstein, followed by the peace of Stockholm with Sweden a few months later the same year. The Hanseatic cities were excepted from the Sound Dues but they had to accept Dutch competition in the Baltic trade. The Danish Duchy of Schleswig was ceded to the count of Holstein. Sweden's autonomous rights and privileges were extended. These peace agreements weakened Eric's position dramatically, and in 1439 he got dethroned by Danish, Swedish and Norwegian Privy Councils.
[EX A]: Around how many months do these events span?

[EX Q]: Passage: The Browns hosted the Pittsburgh Steelers, who were coming off a loss against the Cowboys. The Steelers defeated the Browns 24-9, dropping the Browns to 0-11. With the loss, the Browns were mathematically eliminated from postseason contention for the 14th consecutive season. For the second consecutive season, they were the first NFL team to be mathematically eliminated from contention. The Browns have now gone 24 consecutive seasons without winning a division title, extending the longest active streak in the NFL. They also extended their current franchise record for most consecutive games lost to 14 games. The team is also the first team to start 0-11 since the 2011 Indianapolis Colts.
[EX A]: How many points did the Browns lose by?

[EX Q]: Passage: Richard Colvin Reid , also known as the Shoe Bomber, is a British terrorist who attempted to detonate an explosive device packed into his shoes while on American Airlines Flight 63 from Paris to Miami in 2001. Born to a father who was a career criminal, Reid converted to Islam as a young man in prison after years as a petty criminal. Later he became radicalized and went to Pakistan and Afghanistan, where he trained and became a member of al-Qaeda. On 22 December 2001, he boarded American Airlines Flight 63 between Paris and Miami, wearing shoes packed with explosives, which he unsuccessfully tried to detonate. Passengers subdued him on the plane, which landed at Logan International Airport in Boston, Massachusetts, the closest US airport. He was subsequently arrested and indicted. In 2002, Reid pleaded guilty in U.S. federal court to eight federal criminal counts of terrorism, based on his attempt to destroy a commercial aircraft in flight. He was sentenced to 3 life terms plus 110 years in prison without parole and is currently being held at ADX Florence, a super maximum security prison in the United States.
[EX A]:
About how many years passed between when the Shoe Bomber tried to bomb American Airlines Flight 63 and when he pleaded guilty?
