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: 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.
Example Output: How many fewer households were there compared to housing units?

Example Input: Passage: Hoping to rebound from their divisional road loss to the Packers, the Vikings' Week 11 opponent was the Oakland Raiders, who had former Vikings quarterback Daunte Culpepper under center. After a 79-yard pass from wide receiver Sidney Rice to Visanthe Shiancoe on the first play from scrimmage, the Vikings scored on the very next play on a 10-yard run from Chester Taylor. This was followed by a safety when Culpepper was penalized for intentional grounding in his own endzone. Two plays after the ensuing free kick, the Vikings fumbled the ball just inside Oakland territory, allowing the Raiders to set up a 42-yard field goal for Sebastian Janikowski. On the next drive, the Vikings restored their nine-point lead as kicker Ryan Longwell hit a 30-yard field goal on the first play of the second quarter. A short Oakland drive culminating in 10-yard touchdown pass from Culpepper to tight end John Madsen, followed by another Janikowski field goal, saw the Raiders take the lead for the first time. Four plays later, Minnesota regained a six-point lead on a 38-yard touchdown run from Taylor, but field goals of 42 and 49 yards from Janikowski meant the first half ended with the scores level at 19-19. The Vikings recorded the only score of the third quarter on a 38-yard field goal from Longwell, though they did finish the period on the Raiders' 6-yard line, allowing Taylor to run in his third touchdown on the opening play of the fourth quarter, the first time in his career that he scored three touchdowns in one game. A 52-yard field goal from Janikowski narrowed the margin to 7 points with less than three-and-a-half minutes to play, and after forcing the Vikings to punt just inside the two-minute warning, they had one last chance to level the scores. On the first play of the drive, Culpepper threw the ball in the direction of Justin Fargas, who tipped it up, allowing Chad Greenway to come up with an interception; he went to ground with the ball, but inexplicably got up and attempted to advance it, which allowed left tackle Barry Sims to force a fumble, recovered by right guard Paul McQuistan. That enabled the Raiders to extend their drive, but although they managed to get into Vikings territory, a false start penalty meant Culpepper had to attempt a Hail Mary pass on the final play, but it came up short, giving the Vikings a 29-22 win.
Example Output: How many field goals did Janikowski kick during the first half?

Example Input: Passage: From October 1964 the North Koreans increased the infiltration of intelligence-gatherers and propagandists into the South. By October 1966, more than 30 South Korean soldiers and at least 10 civilians had been killed in clashes with North Korean infiltrators; however, no similar clashes had taken place along the U.S.-controlled section of the DMZ. In October 1966, South Korea staged a retaliatory attack without seeking the approval of General Bonesteel, causing tension between the U.S. command, which wished to avoid violations of the armistice, and the South Koreans, who were suffering ongoing losses. Following the first KPA attack on US forces in November 1966, General Bonesteel formed a working group to analyse the North Korean strategy and develop a counter-strategy to defeat it. Finding the existing U.S. Army tactical doctrines to be inapplicable to the situation they were facing, the working group developed its own doctrine to meet its operational needs. Three types of operations were identified: first to guard against infiltration across the DMZ; second was a similar naval effort along the coasts; and third was counterguerrilla operations in the interior. All three types of operations had to be accomplished without jeopardizing the conventional defense of South Korea or escalating the conflict from low-intensity to a full war.
Example Output:
How many minimum South Korean soldiers and civilians were killed by October 1966?
