TASK DEFINITION: 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.
PROBLEM: 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.

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

PROBLEM: Passage: Trying to snap a two-game losing streak, the Raiders flew to Qualcomm Stadium for a Week 10 AFC West duel with the San Diego Chargers on Thursday night.  Oakland trailed early in the first quarter as Chargers kicker Nick Novak got a 20-yard field goal, yet the Raiders answered with a 2-yard touchdown run from running back Michael Bush.  Oakland added onto their lead in the second quarter with a 23-yard field goal from kicker Sebastian Janikowski, followed by quarterback Carson Palmer finding rookie wide receiver Denarius Moore on a 33-yard touchdown pass. San Diego began the third quarter with quarterback Philip Rivers completing a 30-yard touchdown pass to wide receiver Vincent Brown, yet the Raiders struck back with Palmer hooking up with Moore again on a 26-yard touchdown pass.  Afterwards, the Chargers closed out the quarter with Rivers completing a 7-yard touchdown pass to fullback Jacob Hester.  From there, Oakland's defense held on to preserve the victory. With the win, the Raiders improved to 5-4, and took the lead of the AFC West.

SOLUTION: Which team scored first in the second half?

PROBLEM: Passage: Subsequent negotiations led by Jesuit papal legate Antonio Possevino resulted in the 1582 Truce of Jam Zapolski between Russia and the Polish-Lithuanian Commonwealth. This was a humiliation for the Tsar, in part because he requested the truce. Under the agreement Russia would surrender all areas in Livonia it still held and the city of Dorpat to the Polish-Lithuanian Commonwealth, while Polotsk would remain under Commonwealth control. Any captured Swedish territory—specifically Narva—could be retained by the Russians and Velike Luki would be returned from Batory's control to Russia. Possevino made a half-hearted attempt to get John III's wishes taken into consideration, but this was vetoed by the Tsar, probably in collusion with Batory. The armistice, which fell short of a full peace arrangement, was to last ten years and was renewed twice, in 1591 and 1601. Batory failed in his attempts to pressure Sweden into relinquishing its gains in Livonia, particularly Narva. Following a decision by John, the war with Russia ended when the Tsar concluded the Truce of Plussa  with Sweden on 10 August 1583. Russia relinquished most of Ingria but left Narva and Ivangorod under Swedish control. Originally scheduled to last three years, the Russo-Swedish truce was later extended until 1590. During the negotiations, Sweden made vast demands for Russian territory, including Novgorod. Whilst these conditions were probably only for the purposes of negotiation, they may have reflected Swedish aspirations of territory in the region.

SOLUTION:
How many countries were involved in the 1582 Truce of Jam Zapolski?
