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: Over the centuries, Weimar remained a small town of less than 5,000 inhabitants. When it became the capital of Saxe-Weimar in 1572, population growth was stimulated and population increased from 3,000 in 1650 to 6,000 in 1750. Around the year 1800, Weimar had 7,000 inhabitants. Their number grew constantly over the years to 13,000 in 1850, 28,000 in 1900 and 35,000 at the beginning of World War I. During the interwar period, the new capital of Thuringia saw a population boom, which led to 65,000 inhabitants in 1940. Since that time, the population levels have stagnated. The years 2009 to 2012 brought a moderate growth of approximately 0.35% p. a., whereas the population in bordering rural regions is shrinking with accelerating tendency. Suburbanization played only a small role in Weimar. It occurred after the reunification for a short time in the 1990s, but most of the suburban areas were situated within the administrative city borders.

SOLUTION: Between 1750 and 1900, how many residents did Weimar gain?

PROBLEM: Passage: Coming off their Monday night road win over the Redskins, the Eagles went home for a Week 8 NFC East duel with the New York Giants with the division lead on the line. Philadelphia came out soaring in the first quarter as fullback Leonard Weaver got a 41-yard touchdown run, followed by quarterback Donovan McNabb hooking up with tight end Brent Celek on a 17-yard touchdown pass (with a blocked PAT).  In the second quarter, the Eagles increased their lead as kicker David Akers nailed a 30-yard field goal.  The Giants would get on the board as quarterback Eli Manning found tight end Kevin Boss on an 18-yard touchdown pass, yet Philadelphia kept their momentum going as McNabb completed a 54-yard touchdown pass to wide receiver DeSean Jackson and a 23-yard touchdown pass to rookie wide receiver Jeremy Maclin. The Eagles would increase their lead in the third quarter as Akers booted a 35-yard field goal, yet New York attempted to rally as kicker Lawrence Tynes made a 42-yard field goal and running back Ahmad Bradshaw got a 1-yard touchdown run.  In the fourth quarter, Philadelphia pulled away with a 66-yard touchdown run by rookie running back LeSean McCoy. With the win, not only did the Eagles improve to 5-2, but they would take over as the leader of the NFC East.

SOLUTION: How many field goals did David Akers kick in the second half?

PROBLEM: Passage: Today millions of ethnic Nigerians live abroad, the largest communities can be found in the United Kingdom (500,000-3,000,000) and the United States (600,000-1,000,000 Nigerians), other countries that followed closely are South Africa, Gambia, and Canada respectively. There are also large groups in  Nigerians in Ireland ,  Portugal and many other countries. .Inspiration for emigration is based heavily on socio-economical issues such as warfare, insecurity, economical instability and civil unrest. Between 1400-1900, of 1.4 million of 2 million emigrants were slaves sent to the Americas. This is due to the fact that the land now known as Nigeria was a central point for 4 slave trades during the 19th century. Though bondage represented a great deal, an estimated 30,000 Nigerian inhabitants would relocate to Kano City and Gambia to take advantage of financial opportunities afforded by fertile land and available natural resources. Whats more, the presence of gold mines and rail lines along the Gold Coast, present-day Ghana, attracted an estimated 6,500 Nigerian citizens to attain financial gain and opportunity. The population of Nigerians in Ghana rose to roughly 149,000 before the 1969 alien expulsion order would displace nearly the entire population to surrounding countries.

SOLUTION:
How many North American countries host large ethnic Nigerian populations?
