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.

Passage: The Vikings took their 2010 bye week in Week 4 of the season - their earliest bye week since the 2004 season. There were mixed results for their divisional rivals, with the Green Bay Packers beating the Detroit Lions by 2 points, while the Chicago Bears were beaten 17-3 by the New York Giants. In the days leading to their Week 5 game, the Vikings pulled off a dramatic trade, acquiring receiver Randy Moss from the New England Patriots. The move reunited Moss with the team that drafted him in 1998 and came after Moss caught 50 touchdowns with New England, including a one-handed touchdown catch against the Jets four weeks earlier.
How many points did the Chicago Bears lose by?

Passage: According to the Census Bureau, the median household income in 2013 was $36,836, down 7.9 percent from 2008 when the inflation-adjusted median household income was $40,008 (in 2013 dollars). For comparison, on an inflation-adjusted basis, the median household income among metropolitan areas was $60,482, down 8.2 percent in the same period, and the national median household income was $55,250, down 7.0 percent from 2008. The citys wealth disparity is evident when neighborhoods are compared. Residents in Society Hill had a 2013 median household income of $93,720, while residents in one of North Philadelphias districts reported the lowest median household income, $14,185.
How many dollars difference is the 2013 median household income for the residents in Society Hill compared to the lowest median household income in one of North Philadelphia's districts?

Passage: The first true estimate of the population of Bolivia came in 1826, which 997,427 inhabitants were estimated. This number was calculated from the 1796 census organized by Francisco Gil de Taboada, which consisted of several Bolivian cities. The first modern census was completed in 1831, and ten have been completed since then. The organizer of Bolivians censuses has changed throughout the years—Andrés de Santa Cruz (1831), The Bolivian Statistical Office (1835, 1854, 1882), The Bolivian Statistical Commission (1845), The National Immigration Bureau and The Statistics and Geographic Propaganda (1900), and The Department of Statistics and Censuses (1950)—with the INE conducting the census since 1976. The national census is supposed to be conducted every ten years, however, the 2012 census was late because of "climatic factors and the financing." The 2012 census data was conducted on 21 November 2012, in which 10,027,254 inhabitants were in the country. The estimated cost of the census was $50 million.

How many different organizers of the Bolivians census has there been throughout the years?
