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: On 24 August, Charles X Gustav joined Wittenberg's forces. The Polish king John II Casimir left Warsaw the same month to confront the Swedish army in the west, but after some skirmishes with the Swedish vanguard retreated southwards to Kraków. On 8 September Charles X Gustav occupied Warsaw, then turned south to confront the retreating Polish king. The kings met at the Battle of Żarnów on 16 September, which like the next encounter at the Battle of Wojnicz on 3 October was decided for Sweden. John II Casimir was exiled to Silesia while Kraków surrendered to Charles X Gustav on 19 October. On 20 October, a second treaty was ratified at Kėdainiai in the north. The Union of Kėdainiai unified Lithuania with Sweden, with Radziwiłł recognizing Charles X Gustav as Grand Duke of Lithuania. Over the following days, most of the Polish army surrendered to Sweden: on 26 October Koniecpolski surrendered with 5,385 men near Kraków, on 28 October Field Crown Hetman Stanisław Lanckoroński and Great Crown Hetman Stanisław "Rewera" Potocki surrendered with 10,000 men, and on 31 October the levy of Mazovia surrendered after the Battle of Nowy Dwór.

SOLUTION: About how many months do these events span?

PROBLEM: Passage: In 2011, the Thessaloniki (regional unit) had a Gross Domestic Product of Euro18.293 billion (ranked 2nd amongst the countrys regional units), comparable to Bahrain or Cyprus, and a per capita of €15,900 (ranked 16th). In Purchasing Power Parity, the same indicators are €19,851 billion (2nd) and €17,200 (15th) respectively. In terms of comparison with the European Union average, Thessalonikis GDP per capita indicator stands at 63% the EU average and 69% in Purchasing Power Parity – this is comparable to the German state of Brandenburg. Overall, Thessaloniki accounts for 8.9% of the total economy of Greece. Between 1995 and 2008 Thessalonikis GDP saw an average growth rate of 4.1% per annum (ranging from +14.5% in 1996 to −11.1% in 2005) while in 2011 the economy contracted by −7.8%.

SOLUTION: Between 1995 and 1996, what was the GDP growth rate of Thessalonikis?

PROBLEM: Passage: Hoping to get their first win of the year, the Titans traveled to the RCA Dome for Week 5, as they played an AFC South match-up with the Indianapolis Colts.  The Titans got off to a surprising start, as QB Vince Young ran 19 yards for a touchdown.  Tennessee would follow it up in the second quarter, as kicker Rob Bironas kicked a 22-yard field goal to give the Titans a 10-0 halftime lead.  In the third quarter, Tennessee would get an unpleasant wake-up call, as Colts QB Peyton Manning completed a 13-yard TD pass to WR Marvin Harrison.  The Titans would get another field goal, as Bironas kicked a 47-yard field goal.  Unfortunately, Tennessee remained winless on the year, as Manning completed a 2-yard TD pass to WR Reggie Wayne in the fourth quarter.  With their loss, the Titans continued to stay at the bottom of the AFC South.  With the loss, the Titans dropped to 0-5.

SOLUTION:
How many field goals did Rob Bironas kick?
