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: The 8,878 housing units averaged 685.5 per square mile (264.7/km²), of which 6,287 (73.6%) were owner-occupied, and 2,256 (26.4%) were occupied by renters. The homeowner vacancy rate was 1.2%; the rental vacancy rate was 5.2%.  Around 17,769 people (77.1% of the population) lived in owner-occupied housing units and 5,280 people (22.9%) lived in rental housing units.
Example Output: How many more housing units were owner-occupied than occupied by renters?

Example Input: Passage: Trying to snap a four-game losing skid, the Broncos flew to the University of Phoenix Stadium for a Week 15 interconference fight with the Arizona Cardinals.  The last time these two teams met each other, Denver won 37-7 at Invesco Field at Mile High on December 29, 2002.  This time, it was a battle of rookie quarterbacks as Matt Leinart went up against Jay Cutler. In the first quarter, the Cardinals trailed early as Cutler completed a 54-yard TD pass to WR Javon Walker and kicker Jason Elam nailed a 30-yard field goal.  In the second quarter, Arizona trailed even further with Elam's 22-yard field goal.  The Cardinals would finally score as kicker Neil Rackers nailed a 49-yard field goal and DE Antonio Smith returned a fumble 4 yards for a touchdown.  However, Denver managed to get one last field goal before halftime as Elam kicked a 30-yard field goal.  In the third quarter, more struggles continued as Cutler completed a 10-yard TD pass to WR Rod Smith.  Arizona would respond with Rackers kicking a 38-yard field goal.  In the fourth quarter, the Broncos continued their pounding on the Cards with RB Mike Bell's 1-yard TD run.  Even though the Cardinals got a 4-yard TD run by RB Edgerrin James, Denver wrapped up Cutler's first NFL win with another 1-yard TD run by Mike Bell.  With the loss, Arizona fell to 4-10.
Example Output: From what yard line did the Cardinals score twice?

Example Input: Passage: After their loss to Atlanta, Washington hosted the Minnesota Vikings, looking to snap an 8-game home losing streak. The first quarter was dominated by the Vikings, as they reached the redzone three times and intercepted Redskins quarterback Robert Griffin III. However, the Redskins defense was able to stiffen in the redzone, holding the Vikings to three Blair Walsh field goals of 20, 27, and 27 yards, to give the Vikings a 9-0 advantage after one quarter. In the second, Washington finally was able to sustain a drive. The Redskins drive stalled at the Vikings' 33-yard line, however, and new Redskins kicker Kai Forbath got his first NFL opportunity, having replaced Billy Cundiff, who was cut earlier in the week, and delivered a 50-yard boot to trim the deficit to 9-3. After a Vikings three-and-out, Washington was able to run an 11-play drive that gave it its first advantage of the game, as Alfred Morris scored on a 1-yard run and gave Washington a 10-9 lead. On Minnesota's ensuing possession, Vikings quarterback Christian Ponder was sacked, fumbled, and the fumble was subsequently recovered by Lorenzo Alexander of Washington, setting the Redskins up at the Vikings 6. Robert Griffin III then found fullback Darrel Young for a 6-yard touchdown pass, extending the Redskins advantage to 17-9. In the third, Washington continued imposing its will, as they drove down the field again, this time culminating in a Robert Griffin III touchdown run, his fifth rushing touchdown of the year, setting a Washington Redskins record for rushing touchdowns by a Redskins QB and extending the Washington advantage to 24-9. The Vikings would not back down, though, and Blair Walsh connected again, this time from 37 yards, his fourth field goal on the day, to cut into the lead, and make it 24-12. In the fourth, the Vikings possessed the ball, but Ponder threw an interception straight into the waiting arms of Redskins free safety Madieu Williams, who returned it 24 yards to put the game nearly on ice, at 31-12 Washington. The Vikings, however, proved resilient. On their ensuing drive, the Vikings found the endzone for the first time on the day, with Ponder finding wide receiver Michael Jenkins for a 9-yard score. Ponder subsequently found Kyle Rudolph on a successful two-point conversion attempt, and the Redskins lead was cut to 31-20. After Washington could not extend its advantage, Minnesota got the ball back. Once again, Minnesota scored, this time Ponder found Rudolph to cut the lead to 31-26. This time, however, the two-point conversion came up short, meaning Minnesota would again need to score a touchdown to complete its rally. However, Washington's rookie QB would see to it that no comeback would be complete on his team on this day, as Griffin, on 3rd-and-6 from his own 24, found a seam on a designed quarterback draw, and raced down the sideline for a 76-yard touchdown run, the longest such rush TD by a QB since Kordell Stewart scrambled for an 80-yard score against the Carolina Panthers in the 1996 season. With the score now 38-26 Redskins, the Vikings tried to rally again, and were able to reach the Redskins' goal line. However, with less than a half minute remaining, DeAngelo Hall intercepted Christian Ponder, to officially preserve the 38-26 win. With the win, Washington improved to 3-3, snapped an 8-game home losing streak, and will have an opportunity to take first place in the NFC East with a victory over the defending Super Bowl XLVI champion New York Giants next week.
Example Output:
How many field goals were kicked during the first half?
