TASK DEFINITION: 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.
PROBLEM: Passage: Hoping to rebound from their tough overtime road loss to the Raiders, the Jets went home for a Week 8 duel with the Kansas City Chiefs.  In the first quarter, New York took flight as QB Brett Favre completed an 18-yard TD pass to RB Leon Washington.  In the second quarter, the Chiefs tied the game as QB Tyler Thigpen completed a 19-yard TD pass to TE Tony Gonzalez.  The Jets would answer with Washington getting a 60-yard TD run.  Kansas City closed out the half as Thigpen completed an 11-yard TD pass to WR Mark Bradley. In the third quarter, the Chiefs took the lead as kicker Connor Barth nailed a 30-yard field goal, yet New York replied with RB Thomas Jones getting a 1-yard TD run.  In the fourth quarter, Kansas City got the lead again as CB Brandon Flowers returned an interception 91 yards for a touchdown.  Fortunately, the Jets pulled out the win with Favre completing the game-winning 15-yard TD pass to WR Laveranues Coles. During halftime, the Jets celebrated the 40th anniversary of their Super Bowl III championship team.

SOLUTION: How long was the last touchdown?

PROBLEM: Passage: As Ghana developed economically, education of the citizenry progressed apace.  In 1890 there were only 5 government and 49 "assisted" mission schools in the whole of the Gold Coast with a total enrollment of only 5,000. By 1920 there were 20 governmental schools, 188 "assisted" mission and 309 "unassisted" mission schools with a total enrollment of 43,000 pupils. By 1940, there were 91,000 children attending Gold Coast schools. By 1950, the 279,000 children attending some 3,000 schools in the Gold Coast. This meant that, in 1950, 43.6% of the school-age children in the Gold Coast colony were attending school.

SOLUTION: How many more "assisted" mission schools were there compared to government schools in 1890?

PROBLEM: 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.

SOLUTION:
After how many ages did migrants introduce Celtic language and culture?
