TASK DEFINITION: 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.
PROBLEM: Passage: As of the census of 2010, there were 47,723 people, 17,816 households, and 11,722 families residing in the city. The population density was 1,754.6/sq mi (677.5/km²).  There were 19,806 housing units at an average density of 749.9 per square mile (289.6/km²).  The racial makeup of the city was 38.32% White (U.S. Census), 57.25% African American (U.S. Census), 1.25% Native American (U.S. Census), 1.85% Asian, 0.14% Pacific Islander (U.S. Census), 1.03% from Race (United States Census), and 1.09% from two or more races.  6.98% of the population were Hispanics in the United States or Latino (U.S. Census) of any race.

SOLUTION: How many fewer households were there compared to housing units?

PROBLEM: Passage: The Cleveland Browns traveled to Oakland for their first road game of the season to face the Oakland Raiders. Historically, the Browns and the Raiders split their all-time series at 27 games a piece heading into week three's game. The Browns had won six of their last seven meetings with the Raiders, but the team fell short by a final score of 26-24, allowing the Raiders to end their eleven-game losing streak. The Browns' first drive was marred by three penalties and a sack, forcing the team into an almost-impossible 3rd-and-40 situation. The Browns were forced to punt, but held the Raiders to a three-and-out series on their first drive. However, the Browns were forced to punt again on their second drive, and allowed the Raiders to score the first points of the game on a 32-yard Sebastian Janikowski field goal, putting the Raiders up 3-0. The Browns' next drive ended prematurely, as quarterback Derek Anderson was intercepted by Raiders linebacker Thomas Howard, who returned the interception 26&#160;yards. The Raiders' next drive was stalled by the Browns, forcing the team to kick a field goal, this time a 22-yard field goal. The Browns were forced to punt again on their next drive, and the Raiders were able to score on a 41-yard touchdown pass from quarterback Josh McCown to wide receiver Ronald Curry. The score was made possible by a brilliant play-action fake, which caused rookie cornerback Eric Wright to bite on the fake, allowing Curry to run untouched to the endzone. The Browns' next drive was again ended by an interception, as Kirk Morrison picked Anderson off and returned the interception 45&#160;yards before being tackled by Braylon Edwards to save the touchdown. The Raiders were held to a field goal, this time 23&#160;yards, despite their outstanding field position, increasing their lead to 16-0. On the kickoff, however, returner Josh Cribbs managed to break down the Raiders' defense en route to a 99-yard kickoff return touchdown, putting the Browns on the board for the first time in the game. The Raiders then fumbled on their next possession, allowing defensive end Simon Fraser to fall on the loose ball. Anderson then led the Browns down the field to a 23-yard Phil Dawson field goal, bringing the Browns within six points as the first half came to a close. Raiders quarterback McCown was replaced by Daunte Culpepper at the start of the second half due to an ankle injury he sustained on a play in which defensive end Robaire Smith fell on his leg during a tackle. Culpepper's entrance into the game was met with a loud series of cheers from Raiders fans, who have wanted to see Culpepper on the field all year. His first drive leading the Raiders in the second half ended with a punt, but the Raiders held the Browns to a three-and-out, forcing another Browns punt. However, on the Raiders' next drive, a 24-yard pass from Culpepper to wide receiver Mike Williams was fumbled and recovered by cornerback Daven Holly. The Browns capitalized on the momentum from the fumble and scored six quick points on a 21-yard pass from Anderson to Edwards, bringing the Browns to within nine points of the Raiders. However, the Raiders' next drive culminated in a one-yard touchdown run by running back Lamont Jordan, increasing the Raiders' lead to 23-17 while taking more than nine minutes off the game clock. The Browns were forced into a three-and-out on their next possession, and allowed the Raiders to score three more fourth-quarter points on a 48-yard Janikowski field goal, capping the Raiders' scoring for the day at 26, putting them ahead 26-17. The Browns would answer back on their next drive as Anderson scrambled from the pocket and scored on a one-yard touchdown run to bring the Browns within two points of the lead. After a Raider punt, the Browns were forced into their two-minute offense and had to get the ball within field goal range to have a chance of winning the game. The Browns managed to get the ball to the Oakland 22-yard line, and the field goal unit took the field with three seconds left on the clock. Kicker Phil Dawson managed to hit the field goal from 40&#160;yards out; however, Raiders coach Lane Kiffin called a timeout just moments before Dawson kicked the ball, effectively icing his kick. With one more chance, the Browns lined up for the field goal again. This time, however, Dawson's field goal was blocked by Tommy Kelly, ending the Browns' chances for a comeback win. With the win, the Raiders ended their eleven-game losing streak and took the lead in the overall series between the two teams, 28-27. Derek Anderson, despite his somewhat disappointing performance, put up nearly 250&#160;yards passing for the second straight week, though running back Jamal Lewis was held to just 56&#160;yards on 15 carries. With the loss, the Browns have extended their already long streak of games without winning two in a row. That last happened the final game of the 2003 season and the first game of 2004.

SOLUTION: How many field goals did Sebastian Janikowski kick?

PROBLEM: Passage: The Lions entered the game looking to sweep a season series from the Bears for the first time since 2007, and did so. Chicago scored on the game's opening possession when Jay Cutler capped a 65-yard drive with a 32-yard TD pass to Brandon Marshall. The Lions tied the game at 7 later in the first quarter when Matthew Stafford found Kris Durham in the back of the end zone with a 5-yard TD pass. On the opening drive of the third quarter, Stafford hit Calvin Johnson with a 4-yard TD pass to put the Lions up 14-7. The Bears narrowed the lead to one point with Robbie Gould field goals of 25 and 32 yards. With 2:22 left in the game, Stafford and Johnson connected again, this time on a 14-yard TD pass play, putting the Lions up 21-13.  Josh McCown, who relieved an injured Cutler, led the Bears on a 74-yard TD drive, capped by an 11-yard pass to Brandon Marshall for the score. Needing a two-point conversion to tie the game, McCown's pass to Dante Rosario sailed out of the end zone, but Detroit's Willie Young was called for roughing the passer, giving the Bears another chance from the 1-yard line. The Bears attempted a rushing play for the conversion, but Nick Fairley tackled Matt Fort&#233; behind the line of scrimmage, ending the Bears hopes. Calvin Johnson's second touchdown reception of the game gave him 63 touchdown catches in his Lions career, surpassing Herman Moore's previous team record of 62. The win secured the Lions the #1 spot in the NFC North division, the first time they have held that spot alone since Week 5 of the 2005 season.

SOLUTION:
How did the bears get another chance at 1 yard line?
