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: Coming off their commanding road win over the Browns, the Cowboys played their Week 2 home opener under the MNF spotlight.  In the last MNF game at Texas Stadium, Dallas would duel with their NFC East foe, the Philadelphia Eagles.  In the first quarter, the Cowboys trailed early as Eagles kicker David Akers got a 34-yard field goal.  Dallas would answer in their first possession with QB Tony Romo completing a 72-yard TD pass to WR Terrell Owens.  Philadelphia replied with Akers kicking a 44-yard field goal, yet the 'Boys immediately added to their lead with rookie RB Felix Jones returning a kickoff 98 yards for a touchdown. The Eagles would take the lead with QB Donovan McNabb completing a 6-yard TD pass to RB Brian Westbrook, along with LB Chris Gocong recovering a Romo fumble in the Cowboys' endzone for a touchdown.  Dallas immediately responded with Romo and Owens hooking up with each other again on a 4-yard TD pass. On Philadelphia's next drive, the referees made two suspect decisions. The first was a non-call on a very obvious facemask on Brian Westbrook that would have given the Eagles a first down. The next call in question was a 40-yard passing interference penalty on Anthony Henry. Replays showed that it was Greg Lewis who grabbed Henry's jersey and pulled him down, not the other way around. With that decision, the Eagles were awarded a first down on the 1-yard line. Westbrook immediately ran it in for a 1-yard TD. On their next possession, Akers' hit a 22-yard field goal. To make the game the highest scoring half ever on MNF, the Cowboys ended the half with kicker Nick Folk getting a 51-yard field goal, bringing the total points for both teams to 54. In the third quarter, the 'Boys regained the lead with Romo's 17-yard TD pass to RB Marion Barber. In the fourth quarter, the Eagles once again took the lead with Westbrook's 1-yard TD run.  Afterwards, the Cowboys rallied with Folk nailing a 47-yard field goal and Barber getting a 1-yard TD run. The Eagles had a chance for a game-winning drive, but Dallas' defense stiffened for the victory, sacking the very elusive McNabb twice. In a game that had 9 lead changes, it also set different point records, including most first half points in MNF history (54) and most combined points in the rivalry's history (78). Also, Terrell Owens (3 receptions for 89 yards and 2 touchdowns) reached 132 career touchdown catches, placing him 2nd on the NFL's all-time touchdown receptions list (behind only Jerry Rice's record of 197).
Example Output: How long were each of Tony Romo's touchdown passes?

Example Input: Passage: There are 186,440 people (up from 181,743 in 2000), 75,177 households, and 57,543 families residing in the city. This amounts to 6.75% of Utahs population, 18.11% of Salt Lake Countys population, and 16.58% of the new Salt Lake metropolitan population. The area within the city limits covers 14.2% of Salt Lake County. Salt Lake City is more densely populated than the surrounding metro area with a population density of 1,688.77/sq mi (1,049.36/km²). There are 80,724 housing units at an average density of 731.2 per square mile (454.35/km²).
Example Output: By how many people did the city grow since 2000?

Example Input: Passage: During 1920, Red Army personnel numbered 402,000 at the Western front and 355,000 for the South-West front in Galicia. Grigoriy Krivosheev gives similar numbers, with 382,000 personnel for the Western Front and 283,000 personnel for the Southwestern Front. Norman Davies shows the growth of Red Army forces on the Polish front in early 1920:.
Example Output:
How many Red Army personnel combined the South west and Western front  numbered by Galicia?
