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: 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: Still trying to acquire their first win of the season, the Bengals flew to Reliant Stadium for a Week 8 duel with the Houston Texans. In the first quarter, Cincinnati's struggles continued as Texans WR Jacoby Jones returned a punt 73 yards for a touchdown. The Bengals responded with kicker Shayne Graham getting a 43-yard field goal. In the second quarter, Houston increased its lead as QB Matt Schaub completed a 6-yard TD pass to WR David Anderson. Cincinnati closed out the half with Graham nailing a 32-yard field goal. In the third quarter, the Texans began to pull away as Schaub completed a 7-yard and a 39-yard TD pass to WR Kevin Walter. In the fourth quarter, Houston sealed the win with RB Steve Slaton getting a 20-yard TD run. With yet another loss, the Bengals would fall to 0-8 and start a season with such a record for the first time since 1994.
How many losses did the Bengals start this game with?

Passage: Genetic research suggests that the earliest settlers migrated from Iberia following the most recent ice age. After the Mesolithic, Neolithic and Bronze Age, migrants introduced a Celtic language and culture. Migrants from the two latter eras still represent the genetic heritage of most Irish people. Gaelic tradition expanded and became the dominant form over time. Irish people are a combination of Gaelic, Norse, Anglo-Norman, French, and British ancestry. The population of Ireland stood at 4,588,252 in 2011, an increase of 8.2% since 2006. As of 2011, Ireland had the highest birth rate in the European Union . In 2014, 36.3% of births were to unmarried women. Annual population growth rates exceeded 2% during the 2002-2006 intercensal period, which was attributed to high rates of natural increase and immigration. This rate declined somewhat during the subsequent 2006-2011 intercensal period, with an average annual percentage change of 1.6%. At the time of the 2011 census, the number of non-Irish nationals was recorded at 544,357, comprising 12% of the total population. This is nearly 2.5 times the number of non-Irish nationals recorded in the 2002 census , when the question of nationality was asked for the first time. The five largest non-national cohorts were Polish , UK , Lithuanian , Latvian and Nigerian respectively.
After how many ages did migrants introduce Celtic language and culture?
