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 Input:
Passage: The Japanese attempted to deny the Russians use of Port Arthur. During the night of 13-14 February, the Japanese attempted to block the entrance to Port Arthur by sinking several concrete-filled steamers in the deep water channel to the port, but they sank too deep to be effective. A similar attempt to block the harbour entrance during the night of 3-4 May also failed. In March, the charismatic Vice Admiral Makarov had taken command of the First Russian Pacific Squadron with the intention of breaking out of the Port Arthur blockade. On 12 April 1904, two Russian pre-dreadnought battleships, the flagship Petropavlovsk and the Pobeda, slipped out of port but struck Japanese mines off Port Arthur. The Petropavlovsk sank almost immediately, while the Pobeda had to be towed back to port for extensive repairs. Admiral Makarov, the single most effective Russian naval strategist of the war, perished on the battleship Petropavlovsk. On 15 April 1904, the Russian government made overtures threatening to seize the British war correspondents who were taking the ship Haimun into warzones to report for the London-based Times newspaper, citing concerns about the possibility of the British giving away Russian positions to the Japanese fleet. The Russians quickly learned, and soon employed, the Japanese tactic of offensive minelaying. On 15 May 1904, two Japanese battleships, the Yashima and the Hatsuse, were lured into a recently laid Russian minefield off Port Arthur, each striking at least two mines. The Hatsuse sank within minutes, taking 450 sailors with her, while the Yashima sank while under tow towards Korea for repairs. On 23 June 1904, a breakout attempt by the Russian squadron, now under the command of Admiral Wilgelm Vitgeft, failed. By the end of the month, Japanese artillery were firing shells into the harbour.

Ex Output:
How many days passed between the two Russian pre-dreadnaught battleships struck mines and the two Japanese battleships triking mines?

Passage: Hoping to continue their winning streak, the Bears flew to Cowboys Stadium for an NFC matchup with the Cowboys. In the first quarter Chicago took the early lead as kicker Robbie Gould nailed a 38-yard field goal. Then they trailed with WR Dez Bryant returning a punt 62 yards to the endzone for a touchdown. While the Cowboys were able to pressure quarterback Jay Cutler in the early stages of the game, the Bears' offense made adjustments and regained momentum.  The Bears got the lead back when Cutler made a 39-yard TD pass to tight end Greg Olsen. In the second quarter the Bears trailed again when QB Tony Romo made a 1-yard touchdown pass to RB Chris Gronkowski, but took the lead with Cutler making a nine-yard TD pass to WR Devin Hester. The Bears increased their lead when kicker Robbie Gould made a 40-yard field goal. In the third quarter Dallas would reply with kicker David Buehler nailing a 28-yard field goal. The Bears increased their lead in the fourth quarter when Cutler made a three-yard TD pass to RB Matt Forte. The Cowboys made the final score of the game with Buehler hitting a 48-yard field goal.

Ex Output:
How many field goals between 20 and 60 yards were made?

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 Output:

How many percentage points did the GDP lose between 2007 and 2009?
