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.

Passage: The Easter Rising lasted from Easter Monday 24 April 1916 to Easter Saturday 29 April 1916. Annual commemorations, rather than taking place on 24-29 April, are typically based on the date of Easter, which is a moveable feast. For example, the annual military parade is on Easter Sunday; the date of coming into force of  the Republic of Ireland Act 1948 was symbolically chosen as Easter Monday  1949. The official programme of centenary events in 2016 climaxed from 25 March  to 2 April  with other events earlier and later in the year taking place on the calendrical anniversaries.
How many days did the Easter Rising last for?

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.
How many more percentage does the financial services industry make of tax base make than the city's work?

Passage: Following Henry VIII of England of England and his infamous "Great Debasement" program that began 1526, the Spanish King Philip III tried to cement his Spanish legacy through changes in coinage strategy. Previously, Spanish Kings (at least from 1471) issued a largely copper fractional coinage called blancas, with a nominal money-of-account value of 0.5 maravedí, but with a very small amount of silver to convince the public that it was indeed precious-metal "money". The blanca issued in 1471 had a silver fineness of 10 grains or 3.47% (weighing 1.107g). In 1497, that fineness was reduced to 7 grains (2.43% fine); in 1552, to 5.5 grains (1.909% fine); in 1566, to 4 grains (1.39% fine). By the start of the 17th century, inflation took hold of Spain as the gap between nominal and silver-based prices dramatically shifted. The purely copper coinage had done its damage to Spain. The difference between the silver- and vellon-based price indexes in Spain showed that the purely copper coinage other European countries used made up a much smaller proportion of the total coined money supply (something the Spanish Kings had overlooked and Malestroit was able to pinpoint).

Did the blanca have a higher fineness in 1471 or 1497?
