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: After the political changes, in 1991, Bulgaria had a US$11.25 billion state debt, which represented 180% of the GDP. The state debt peaked in 1994, when it reached US$14.4 billion. During 1998-2008 Bulgaria maintained policy of Government budget balance, which reduced the state debt to 5.07 billion euro. Combined with the economic growth in that period, the state debt dropped to a record low of 13.7% of GDP, one of the lowest in the European Union. In 2008 Bulgaria also maintained 4.286 billion euro fiscal reserve, meaning that net state debt at this moment was only 0.784 billion euro. After the Financial crisis of 2007–08 Bulgaria turned to policy of Deficit spending and at the end of 2013 the state debt rose up to 7.219 billion euro, representing 18.1% of the GDP. In 2015, the debt rate increased further to 26.7% of the GDP, still remaining the third lowest in EU after Estonia and Luxembourg. Part of the increase was driven by the collapse of Corporate Commercial Bank in 2014, the fourth largest bank in the country, and the subsequent paying out of Deposit insurance.

Ex Output:
For how many years did Bulgaria maintain a policy of a balanced budget?

Passage: The Chiefs defense began the game by demonstrating how unpredictable they have been all season.  After giving up three plays of 10 yards or more, Mike Brown intercepted what would likely have been a touchdown pass, giving the Chiefs offense a chance to take the field.  After a short run and two incomplete passes, the Chiefs punted back to Denver.  The Chiefs defense nearly forced the Broncos to a three-and-out, but the drive was kept going by a Ron Edwards face mask call.  The end result was a Kyle Orton to Daniel Graham touchdown pass. The Chiefs offense responded by putting together a relatively long series that began at the KC 31 and lasted 20 plays, ending in a 22-yard Ryan Succop field goal.  After a couple possession changes, the Broncos answered with a series that included three Correll Buckhalter rushes for over 10 yards, ending in a Knowshon Moreno rushing touchdown.  The Chiefs would respond before the half with another field goal. The second began with the Chiefs failing to convert on fourth down and the Broncos scoring on each of their first three possessions.  Before the end of the quarter, Matt Cassel was replaced by Brodie Croyle.  After the Chiefs lost a Jamal Charles fumble for a touchdown, they recovered a Kyle Orton fumble and eventually turned it into a Jamal Charles rushing touchdown.  The Broncos immediately responded with yet another touchdown.

Ex Output:
How many field goals did the Chiefs make in the first half?


Ex Input:
Passage: After the fall of Pegu, remnants of Mon resistance fell back to the upper Tenasserim peninsula , and remained active there with Siamese support. However, the resistance was disorganized, and did not control any major towns. It remained active only because Konbaung's control of the upper Tenasserim peninsula in 1757-1759 was still largely nominal. Its effective control still did not extend beyond Martaban as the majority of the Konbaung armies were back north in Manipur and in the northern Shan states. However, no single southern leader emerged to rally the Mon populace as Alaungpaya did with the Burmans in 1752. A rebellion broke out in 1758 throughout Lower Burma but was put down by local Konbaung garrisons. The window of opportunity came to a close in the second half of 1759 when the Konbaung armies, having conquered Manipur and the northern Shan states, were back down south, preparing for their invasion of the Tenasserim coast and Siam. The Konbaung armies seized the upper Tenasserim coast following the Burmese-Siamese War , and pushed out the Mon resistance farther down the coast.  The resistance was driven out of Tenasserim in 1765 when Alaungpaya's son Hsinbyushin seized the lower coastline as part of the Burmese-Siamese War .

Ex Output:

How many years did Konbaung control the upper Tenasserim peninsula?
