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.

Example Input: Passage: Forecasting airline interest in larger-capacity models, Boeing announced the stretched 767-300 in 1983 and the extended-range 767-300ER in 1984. Both models offered a 20 percent passenger capacity increase, while the extended-range version was capable of operating flights up to . Japan Airlines placed the first order for the 767-300 in September 1983. Following its first flight on January 30, 1986, the type entered service with Japan Airlines on October 20, 1986. The 767-300ER completed its first flight on December 9, 1986, but it was not until March 1987 that the first firm order, from American Airlines, was placed. The type entered service with American Airlines on March 3, 1988. The 767-300 and 767-300ER gained popularity after entering service, and came to account for approximately two-thirds of all 767s sold.
Example Output: How many months after the first flight of the 767-300 was the first flight of the 767-300ER?

Example Input: Passage: After securing their first win of the season, the Browns went on the road to take on their archrival Pittsburgh Steelers. The Browns came into the game having lost their last 11 games against the Steelers. The Steelers struck first with two touchdown passes from Ben Roethlisberger in the 2nd quarter. Josh Cribbs ran a kickoff back 98 yards for a touchdown, and got the Browns within 7. However, the Browns could never close the gap, and fell to the Steelers, 27-14.
Example Output: How many games have the Browns won this season?

Example Input: Passage: Hoping to rebound from their divisional road loss to the Chiefs, the Broncos went home for a Week 5 interconference duel with the Tampa Bay Buccaneers.  In the first quarter, Denver trailed early as Bucs kicker Matt Bryant got a 33-yard field goal.  In the second quarter, the Broncos took the lead as kicker Matt Prater got a 55-yard and a 40-yard field goal.  Tampa Bay would tie the game at halftime as Bryant kicked a 31-yard field goal.  In the third quarter, Denver took a big lead as QB Jay Cutler completed a 10-yard TD pass to WR Brandon Stokley.  In the fourth quarter, the Broncos increased its lead as Prater nailed a 27-yard field goal.  The Buccaneers would try to rally as QB Jeff Garcia completed a 7-yard TD pass to WR Ike Hilliard.  Fortunately, Denver recovered the onside kick and drained the clock.
Example Output:
How many field goals between 25 and 60 yards were made?
