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: 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 200708 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.

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

Question: Passage: The Raiders opened the home portion of their schedule against the New York Jets. After the teams exchanged three-and-outs on their first possessions, the Raiders moved downfield on an 81-yard drive that culminated in a Derek Carr to Michael Crabtree two-yard touchdown pass to give the Raiders an early 7-0 lead. After another Jets punt, the Raiders went 85 yards as Carr hit Crabtree from 26 yards out to extend the lead to 14-0. The Jets answered with a 75-yard drive which ended with a Jermaine Kearse 34-yard pass from Josh McCown for a touchdown, reducing the Raider lead to 14-7. The Raider offense stalled on their next two possessions as the Jets added a 46-yard field goal to narrow the lead to 14-10. With 1:50 remaining in the first half, the Raiders were forced to punt, but Jet returner Kalif Raymond muffed the punt and the Raiders recovered at the Jets four yard line. Three plays later, Oakland native Marshawn Lynch scored from two yards out, his first touchdown as a Raider, to give the Raiders the 21-10 halftime lead. The Jets began the second half with a field goal that again narrowed the lead, this time to 21-13. The Raiders, however, answered the score convincingly, scoring three touchdowns on their next three possessions as Cordarelle Patterson and Jalen Richard each scored on long rushing plays and Carr hit Crabtree again from 19 yards out after a Jets fumble to push the lead to 42-13. The Jets added a touchdown midway through the fourth period, but the Raider offense ate up the remaining time on the clock, using 8:17 to go 32 yards before a Georgio Tavecchio 29-yard field goal pushed the lead to 45-20 with 25 seconds remaining. The 45-20 win moved the Raiders to 2-0 on the season, the first time since 2002 that they had started a season 2-0. Derek Carr completed 23 of 28 passes for 230 yards and three touchdowns, all to Michael Crabtree. Crabtree caught six passes for 80 yards to go along with his three touchdowns. Marshawn Lynch only rushed for 45 yards on 12 carries, but did get a touchdown as the Raiders rushed for 180 yards in the game. The Raider defense played well again limiting the Jets to 276 yards in the game and sacking Jets QB Josh McCown four times.

Answer:
How many Derek Carr passes were not completed?
