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 Liberian economy had relied heavily on the mining of iron ore prior to the civil war. Liberia was a major exporter of iron ore on the world market. In the 1970s and 1980s, iron mining accounted for more than half of Liberia's export earnings. Since the coup d'état of 1980, the country's economic growth rate has slowed down because of a decline in the demand for iron ore on the world market and political upheavals in Liberia. Following a peak in growth in 1979, the Liberian economy began a steady decline due to economic mismanagement following the 1980 coup. This decline was accelerated by the outbreak of civil war in 1989; GDP was reduced by an estimated 90% between 1989 and 1995, one of the fastest declines in history. The United Nations imposed sanctions on Liberia in May 2001 for its support to the rebels of the Revolutionary United Front  in neighboring Sierra Leone. These sanctions have been lifted following elections in 2005. Upon the end of the war in 2003, GDP growth began to accelerate, reaching 9.4% in 2007. The global financial crisis slowed GDP growth to 4.6% in 2009, though a strengthening agricultural sector led by rubber and timber exports increased growth to 5.1% in 2010 and an expected 7.3% in 2011, making the economy one of the 20 fastest growing in the world. In March 2010, Bob Johnson, founder of BET, funded the first hotel constructed in Liberia in 20 years. The 13-acre  luxury resort was built in the Paynesville section of Monrovia. Liberia's external debt was estimated in 2006 at approximately $4.5 billion, 800% of GDP. As a result of bilateral, multilateral and commercial debt relief from 2007 to 2010, the country's external debt fell to $222.9 million by 2011.
[EX A]: How many percentage points did the GDP lose between 2007 and 2009?

[EX Q]: Passage: The Philadelphia Eagles opened up the season by traveling to Cleveland to square off against the Browns.  A 43-yard field goal by veteran Browns kicker Phil Dawson gave Cleveland a 3-0 lead some six minutes into the first quarter.  The Eagles would respond with a field goal of their own, though, as Alex Henery sent the ball through the uprights from 42-yards out just seconds into the second period.  With the score tied at 3-3 and just seventeen seconds before the half, an 18-yard pass from Eagles' quarterback Michael Vick to wideout Jeremy Maclin extended the Eagles lead by seven.  At the half, the score was 10-3, the Eagles leading the Browns by a seven-point margin.  Browns kicker Phil Dawson successfully converted another field goal from 42-yards away with just under five minutes left in the third quarter, trimming the score to 10-6.  Shortly afterwards, Dawson made the score 10-9 with a 22-yard field goal, his third of the day, and narrowing the Eagles' lead to one point with about fourteen minutes left in the game.  The underdog Browns continued the scoring streak, taking the lead on an errant Michael Vick throw and 27-yard interception return touchdown by D'Qwell Jackson approximately thirty seconds later.  With the score at 16-10 and an upset in the works, Michael Vick calmly drove the Eagles down the field and threw a strike to Clay Harbor from 4-yards out to return the lead to Philadelphia, 17-16.  The Browns were unable to reciprocate and the Philadelphia Eagles narrowly claimed the week one victory.  With the nail-biting win, the Eagles began their season 1-0.
[EX A]: How far was the longest field goal in the game?

[EX Q]: Passage: Trying to snap their three-game losing streak, the Lions flew to Gillette Stadium for a Week 13 fight with the New England Patriots.  In the first quarter, Detroit trailed early as kicker Stephen Gostkowski nailed a 25-yard field goal for the only score of the period.  In the second quarter, the Lions took the lead with QB Jon Kitna completing a 5-yard TD pass to WR Mike Furrey, while kicker Jason Hanson got a 29-yard field goal.  However, New England would reclaim the lead with RB Corey Dillon's 6-yard TD run and Gostkowski's 27-yard field goal.  In the third quarter, Detroit came right back with Hanson's 38-yard and 49-yard field goal, while DE Jared DeVries sacked Pats QB Tom Brady in his endzone for a safety.  In the fourth quarter, Hanson would kick a 26-yard field goal.  However, their lead would vanish for good, as Dillon got a 2-yard TD run, which was followed up with Brady successfully completing a 2-point conversion pass to WR Troy Brown.  Dillon would then wrap the game up with a 4-yard TD run.  With their fourth-straight loss, the Lions fell to 2-10.
