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 Q]: Passage: On 17 January 2011, it was announced that Motörhead would be part of the Sonisphere Festival in Knebworth. In August 2011, they headlined the Brutal Assault open-air festival in the Czech Republic. On 2 March 2011 Motörhead performed on Late Night with Jimmy Fallon.

The Gigantour took place from 26 January to 28 February 2012, but Motörhead missed the final four shows because Lemmy had a combination of an upper respiratory viral infection and voice strain, resulting in severe laryngitis. Lemmy wrote on Facebook, "Im giving my voice a good rest", hoping he would recover soon to play at the Mayhem Festival, which was held from 30 June to 5 August 2012. Motörhead also took part on 23 June in the Rock-A-Field Luxembourg Open Air Festival in Roeser.

[EX Q]: Passage: The Chargers rallied from a 21-point deficit, and Novak kicked the game-winning 40-yard field goal in overtime to defeat the San Francisco 49ers 38-35. Rivers, who sat out practice earlier in the week with back and chest injuries, overcame three interceptions to throw for 356 yards and four TDs. The Chargers, who played the game without injured offensive stars Allen and Mathews, outscored the 49ers 31-7 after halftime. The win kept San Diego's slim playoff chances alive. The 49ers led 28-7 at halftime, aided by a 49-yard TD return of a Rivers interception by Antoine Bethea. San Francisco rushed for 365 yards, the most the Chargers had surrendered since Adrian Peterson set a single-game record of 296 in 2007. Running back Frank Gore had 158, and quarterback Colin Kaepernick added 151, including a 90-yard TD run in the third quarter. In the fourth, Gates caught one of his two touchdowns in the second half, and Rivers connected with Floyd with 29 seconds remaining for the game-tying score, set up by two long fourth-down conversions earlier in the drive. The game went into overtime after 49ers kicker Phil Dawson missed a 60-yard field goal attempt at the end of regulation. On the opening drive in overtime, Weddle forced a fumble by receiver Quinton Patton, which was recovered by San Diego's Sean Lissemore. The Chargers drove, and Novak hit the game-winner nearly five minutes into the extra period. Rivers completed 33 of 54 passes in the game. The Chargers were playing with their fifth-string center, and rookie right guard Jeremiah Sirles was making his NFL debut. The offense converted all three of their fourth-down conversions after entering the game with the worst conversions rate at 20% (1-of-5). It was the 49ers fourth consecutive loss. It was only the second time ever that San Francisco had lost after leading by 21 or more at the half.
[EX A]:
How many is the difference in the yards River threw for and the yards Gore had?
