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 Input:
Passage: Coming off their win over the Giants, the Cowboys stayed at home for a Week 16 interconference battle with the Baltimore Ravens, in what would be the final game at Texas Stadium. In the first quarter, Dallas struck first as rookie running back Tashard Choice got a 2-yard touchdown run.  The Ravens would respond with a 26-yard field goal from kicker Matt Stover.  Baltimore would take the lead in the second quarter as Stover got a 29-yard and a 37-yard field goal.  In the third quarter, the Ravens increased their lead as quarterback Joe Flacco completed a 13-yard touchdown pass to wide receiver Derrick Mason.  The Cowboys answered in the fourth quarter as kicker Nick Folk got a 35-yard field goal, but Baltimore answered right back with Stover's 35-yard field goal.  Dallas tried to rally as quarterback Tony Romo completed a 7-yard touchdown pass to wide receiver Terrell Owens, but the Ravens struck right back as running back Willis McGahee got a 77-yard touchdown run.  The Cowboys tried to come back as Romo completed a 21-yard touchdown pass to tight end Jason Witten, but the Ravens pulled away with fullback Le'Ron McClain's 82-yard touchdown run (the longest TD run that the Cowboys would ever give up during their tenure at Texas Stadium). With the loss, Dallas fell to 9-6 on the season and 0-3 all-time against the Ravens. For a while they lost their chances of controlling the NFC Wild Card spot, but got it back the next day with the Tampa Bay Buccaneers losing 41-24 to the San Diego Chargers.

Ex Output:
How long were each of Tony Romo's touchdown passes?

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.

Passage: Sixteen international airlines provided regular flights to Khartoum. The number of domestic and international passengers increased from about 478,000 in 1982 to about 485,000 in 1984. Air freight increased from 6 million tons per kilometer in 1982 to 7.7 million tons per kilometer in 1984. As compared with the previous year, in 1989 passenger traffic on Sudan Airways fell by 32% to 363,181 people, reducing the load factor to 34.9%. By contrast, freight volume increased by 63.7% to 12,317 tons. At the end of 1979, Sudan Airways had entered into a pooling agreement with Britains Tradewinds Airways to furnish charter cargo service between that country and Khartoum under a subsidiary company, Sudan Air Cargo. A new cargo terminal was built at Khartoum.

Ex Output:

By how many millions of tons did air freight increase between 1982 and 1984?
