instruction:
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.
question:
Passage: Coming off their dominating road win over the Jaguars, the Eagles went home for their Week 4 NFC East duel with the Washington Redskins, as quarterback Donovan McNabb made his highly anticipated return to Philadelphia. The Eagles trailed in the first quarter as Redskins running back Ryan Torain got a 12-yard touchdown run, followed by McNabb's 31-yard touchdown pass to tight end Chris Cooley.  Philadelphia answered in the second quarter with kicker David Akers making a 49-yard field goal, but Washington came right back with kicker Graham Gano's 26-yard field goal.  Afterwards, the Eagles closed out the half with Akers' 23-yard field goal.  After a scoreless third quarter, Philadelphia tried to rally in the fourth quarter as quarterback Kevin Kolb hooked up with tight end Brent Celek.  However, the Redskins' defense prevented any further progress.
answer:
How many field goals did Akers make?


question:
Passage: After a gradual 5-year recovery to an intraday high of 2,239.51 on October 31, 2007, the highest reached since February 16, 2001, the index corrected below the 2,000 level in early 2008 amid the Late-2000s recession, the United States housing bubble and the Financial crisis of 2007-2010. Panic focusing on the failure of the investment banking industry culminated in a loss of more than 10% on September 29, 2008, subsequently plunging the index firmly into bear market territory. The NASDAQ-100, with much of the broader market, experienced a Limit down open on October 24 and reached a 6-year intraday low of 1,018 on November 20, 2008.
answer:
How many months passed between the index high and its 6-year intraday low?


question:
Passage: Following the Revolution of 1905, the Tsar made last attempts to save his regime, and offered reforms similar to most rulers when pressured by a revolutionary movement. The military remained loyal throughout the Revolution of 1905, as shown by their shooting of revolutionaries when ordered by the Tsar, making overthrow difficult. These reforms were outlined in a precursor to the Constitution of 1906 known as the October Manifesto which created the Imperial Duma. The Russian Constitution of 1906, also known as the Fundamental Laws, set up a multiparty system and a limited constitutional monarchy. The revolutionaries were quelled and satisfied with the reforms, but it was not enough to prevent the 1917 revolution that would later topple the Tsar's regime.
answer:

How many years after the 1905 revolution was the revolution that would topple the Tsar?
