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 Q]: 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.
[EX A]: How many fewer households were there compared to housing units?

[EX Q]: Passage: The Ravens were facing the Tampa Bay Buccaneers, a team with an identical 7-3 record. However, the Ravens were considered favorites going into the game, given that they had never lost at home during the season, and all Tampa Bay wins were against teams with losing records. Still, they did not take this one lightly. After a scoreless first quarter, the Ravens scored first with a field goal. Tampa Bay later tied it, but Baltimore scored two touchdowns, including one on a 65-yard pass from Todd Heap, to have a 17-3 halftime lead. During a scoreless third quarter, a would be long TD-run from Ray Rice was negated by a controversial call of a penalty on Anquan Boldin. Though the Ravens would never score anymore in the game, they managed to hold off Tampa Bay and allow just one touchdown, enough to prevent their lead from being blown.
[EX A]: How long was Todd Heaps touchdown?

[EX Q]: Passage: Mike Evans caught two touchdown passes from Mike Glennon, as Tampa Bay led 17-16 in the fourth quarter. Cleveland scored with 8:59 remaining in regulation, and won the game by the score of 22-17. In the final two minutes, Tampa Bay drove to the Cleveland 28 yard line, but an offensive pass interference penalty pushed them back to the 47. Facing 4th down & 11, Glennon's pass was incomplete, and the Browns defeated Tampa Bay for the first time since 1995.
[EX A]:
How many points did Cleveland score in total?
