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: In the early game the Giants were crushed by the Rams 31–3, thus forcing the 49ers to win their game to clinch the division. In wet, rainy conditions in Oakland, the 49ers dominated the Raiders, 38–7, giving the 49ers their first divisional title, making them champions of the NFC West. The 49ers won their divisional playoff game 17–14 against the defending conference champion 1970 Minnesota Vikings season, thus setting up a matchup against the 1970 Dallas Cowboys season for the NFC championship. In the final home game for the 49ers at Kezar Stadium the 49ers kept up with the Cowboys before losing, 17–10, thus giving the Cowboys their first conference championship. The 49ers sent five players to the 1970 Pro Bowl that season, including MVP veteran quarterback John Brodie, wide receiver Gene Washington (49ers), and linebacker Dave Wilcox. Nolan was also named NFL Coach of the Year for 1970. Following the 1970 season the 49ers moved from Kezar Stadium to Candlestick Park. Despite being located on the outskirts of the city, Candlestick Park gave the 49ers a much more modern facility with more amenities that was easier for fans to access by highway.
[EX A]: By how many points did the 49ers win against the Raiders?

[EX Q]: Passage: Couceiro had undertaken a first incursion in 1911 with about 1,000 men, who had formed in groups of 60-70 men. They had left the town of Verín, 12 kilometers from the northern border with Spain, and had marched towards the border. Most of the men were from the region of Trás-os-Montes and were from a diverse array of social classes and skills. There were more than 100 priests in the group. In terms of military equipment, there were only 400 ancient rifles, a few Winchester rifles, and Mauser Pocket Pistols adapted to rifles, to which were added a score of semi-automatic pistols, daggers, and swords. The 1,000 men had crossed the border after a long march in the mountainous region between Bragança and Vinhais, near the present-day Montesinhos National Park. The republican garrison in Bragança had waited for an attack that never came. This is because the royalists had changed their plans and now marched on Vinhais, which had a smaller garrison of men—only eighty infantry, cavalry and border guards. These forces from Vinhais had left the small town and had concentrated on a hill nearby. Negotiations were begun but the military commander of Vinhais refused to join or to surrender. He gave Paiva Couceiro two hours to abandon Portuguese territory.
[EX A]:
At least, how many groups of men did Couceiro take with him in 1911?
