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.

Passage: Crimean Khan Haji Giray, learning of the defeat of the Budjak Tatars gathered 10,000-12,000 men and went against Kunitsky. At the end of December Kunitsky with 10,000-12,000 Cossacks and Moldavians left Budjak and began to cross the Prut River near the village of Tobak, not far from the town of Reni, Ukraine. Here on 30 December they were suddenly attacked by Tatar cavalry under Khan Haji Giray. Kunitsky built a fortified camp and successfully repelled the Tatar attacks. On the night of 3 to 4 January 1684 the Moldavian allies betrayed the Cossacks and left the Cossack camp. In this situation Kunitsky with the Cossack cavalry  broke through the enemy ring and crossed the Prut. The Cossack infantry  under Andrey Mogila also broke out and crossed the Prut near Boyanova, but suffered heavy losses. By 10 January only five thousand Cossacks reached Jassy.
How many days after the Cossacks and Moldavians were attacked by Tatar calalry under Khan Haji Giray did the Moldavian allies betray the Cossacks?

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

Passage: At home, in front of a sellout crowd for the first time since their 2009 Home Opener, the Oakland Raiders battled the Kansas City Chiefs for control of the AFC West. The first score of the game came from the Chiefs as Matt Cassel threw an 11-yard touchdown pass to Verran Tucker to take a lead over the Raiders, 7-0. After a Ryan Succop field goal, the Chiefs led the Raiders 10-0 at the half. The Raiders started the second half strong, as Jacoby Ford returned the opening kickoff 94&#160;yards for a score and cut the Chiefs' lead to 10-7. After Succop kicked yet another field goal for the Chiefs, Oakland took the lead when Jason Campbell threw a 2-yard touchdown pass to Khalif Barnes. Going into the 4th Quarter, the Raiders led 14-13. A fourth quarter Sebastian Janikowski field goal increased the Raiders' lead to 17-13. While the Raiders forced the Chiefs to punt on their next possession, punt-returner Nick Miller was charged with a controversial fumbling call. The play could not be challenged, as coach Tom Cable had used both of the Raiders' call challenges earlier in the game. On the Chiefs' ensuing drive, Cassel hooked up with Dwayne Bowe in the endzone to give the Chiefs a late 20-17 lead. In the dying seconds, the Raiders found themselves trailing until Campbell hooked up with Ford for a huge 41&#160;yard reception setting Janikowski up for the game-tying field goal. The score tied the game at 20-20, sending it into overtime. In overtime, the Raiders quickly forced the Chiefs to punt. On the Raiders' ensuing drive, Jason Campbell again hooked up with Jacoby Ford for a 47-yard pass completion. Sebastian Janikowski kicked a 31-yard field goal to give the Raiders an overtime win. With the win, Oakland went into their bye week at 5-4 and snapped a seven-game home losing streak to the Chiefs. The Raiders' win also gave them their first three-game winning streak since 2002, as well as their first winning record, at any time during a season, since 2004.

How many field goals did Janikowski kick?
