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: Estimates vary about the number and quality of financial jobs in the city. One estimate was that Wall Street firms employed close to 200,000 persons in 2008. Another estimate was that in 2007, the financial services industry which had a $70 billion profit became 22 percent of the citys revenue. Another estimate (in 2006) was that the financial services industry makes up 9% of the citys work force and 31% of the tax base. An additional estimate (2007) from Steve Malanga of the Manhattan Institute was that the securities industry accounts for 4.7 percent of the jobs in New York City but 20.7 percent of its wages, and he estimated there were 175,000 securities-industries jobs in New York (both Wall Street area and midtown) paying an average of $350,000 annually. Between 1995 and 2005, the sector grew at an annual rate of about 6.6% annually, a respectable rate, but that other financial centers were growing faster. Another estimate (2008) was that Wall Street provided a fourth of all personal income earned in the city, and 10% of New York Citys tax revenue.  The citys securities industry, enumerating 163,400 jobs in August 2013, continues to form the largest segment of the citys financial sector and an important economic engine, accounting in 2012 for 5 percent of private sector jobs in New York City, 8.5 percent (US$3.8 billion) of the citys tax revenue, and 22 percent of the citys total wages, including an average salary of US$360,700.
[EX A]: How many more percentage does the financial services industry make of tax base make than the city's work?

[EX Q]: Passage: Following their Monday Night loss to the Raiders, the Broncos remained on home turf to face the Cincinnati Bengals. The Broncos took the lead in the first quarter, with a 1-yard touchdown run by running back Willis McGahee. The Bengals got on the board in the second quarter, with a 45-yard field goal by placekicker Mike Nugent. The Broncos responded, with a 34-yard field goal by placekicker Matt Prater just before halftime. In the third quarter, the Broncos extended their lead, with a 25-yard touchdown pass from quarterback Kyle Orton to wide receiver Eric Decker. The Bengals reeled off 12 unanswered points, with a 37-yard field goal by Nugent, a 10-yard touchdown pass from quarterback Andy Dalton to wide receiver Andre Caldwell (with a failed two-point conversion attempt), followed by a 23-yard field goal by Nugent, narrowing the Broncos' lead to 17-15. In the fourth quarter, the Broncos once again increased their lead, with a 52-yard touchdown pass from Orton to Decker, but the Bengals responded, with a 5-yard touchdown pass from Dalton to wide receiver A. J. Green. The Broncos' defense prevented any more scoring.
[EX A]: How long were each of Mike Nugent's field goals?

[EX Q]: Passage: The Japanese began to catch gray whales beginning in the 1570s. At Kawajiri, Nagato Province, 169 gray whales were caught between 1698 and 1889. At Tsuro, Japan, Shikoku, 201 were taken between 1849 and 1896. Several hundred more were probably caught by American and European whalemen in the Sea of Okhotsk from the 1840s to the early 20th century. Whalemen caught 44 with nets in Japan during the 1890s. The real damage was done between 1911 and 1933, when Japanese whalemen killed 1,449 after Japanese companies established several whaling stations on Korean Peninsula and on Chinese coast such as near the Daya bay and on Hainan Island. By 1934, the western gray whale was near extinction. From 1891 to 1966, an estimated 1,800–2,000 gray whales were caught, with peak catches of between 100 and 200 annually occurring in the 1910s.
[EX A]:
How many decades after whaling started did the western grey whale reach near extinction?
