Problem: Marshall Islands:

Historical population figures are unknown. In 1862, the population was estimated at about 10,000. In 1960, the entire population was about 15,000. In July 2011, the number of island residents was estimated to number about 72,191. Over two-thirds of the population live in the capital, Majuro and Ebeye, the secondary urban center, located in Kwajalein Atoll. This excludes many who have relocated elsewhere, primarily to the United States. The Compact of Free Association allows them to freely relocate to the United States and obtain work there. A large concentration of about 4,300 Marshall Islanders have relocated to Springdale, Arkansas, the largest population concentration of natives outside their island home.

On what atoll is Ebeye located?
---
A: Kwajalein Atoll

Problem: Karl Popper's rejection of Marxism during his teenage years left a profound mark on his thought. He had at one point joined a socialist association, and for a few months in 1919 considered himself a communist. During this time he became familiar with the Marxist view of economics, class-war, and history. Although he quickly became disillusioned with the views expounded by Marxism, his flirtation with the ideology led him to distance himself from those who believed that spilling blood for the sake of a revolution was necessary. He came to realise that when it came to sacrificing human lives, one was to think and act with extreme prudence.
How did Popper's rejection of Marxism in his adult years effect him?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The discovery of infrared radiation is ascribed to William Herschel, the astronomer, in the early 19th century. Herschel published his results in 1800 before the Royal Society of London. Herschel used a prism to refract light from the sun and detected the infrared, beyond the red part of the spectrum, through an increase in the temperature recorded on a thermometer. He was surprised at the result and called them "Calorific Rays". The term 'Infrared' did not appear until late in the 19th century.
Who discovered spectrum radiation?
A: unanswerable

Context and question: In 1993, to complement its own direct sales channel, Dell planned to sell PCs at big-box retail outlets such as Wal-Mart, which would have brought in an additional $125 million in annual revenue. Bain consultant Kevin Rollins persuaded Michael Dell to pull out of these deals, believing they would be money losers in the long run. Margins at retail were thin at best and Dell left the reseller channel in 1994. Rollins would soon join Dell full-time and eventually become the company President and CEO.
What position at Dell did Kevin Rollins eventually lose?
Answer: unanswerable

Question: Canadian football has mostly been confined to Canada, with the United States being the only other country to have hosted a high-level Canadian football game. The CFL's controversial "South Division" as it would come to be officially known attempted to put CFL teams in the United States playing under Canadian rules between 1992 and 1995. The move was aborted after three years; the Baltimore Stallions were the most successful of the numerous Americans teams to play in the CFL, winning the 83rd Grey Cup. Continuing financial losses, a lack of proper Canadian football venues, a pervasive belief that the American teams were simply pawns to provide the struggling Canadian teams with expansion fee revenue, and the return of the NFL to Baltimore prompted the end of Canadian football on the American side of the border.
Is there an answer to this question: Who put NFL teams in the United States playing under Canadian Rules?

Answer: unanswerable

Problem: Thuringia:

The name Thuringia or Thuringen derives from the Germanic tribe Thuringii, who emerged during the Migration Period. Their origin is not completely known. An older theory claimed that they were successors of the Hermunduri, but later research rejected the idea. Other historians argue that the Thuringians were allies of the Huns, came to central Europe together with them, and lived before in what is Galicia today. Publius Flavius Vegetius Renatus first mentioned the Thuringii around 400; during that period, the Thuringii were famous for their excellent horses.

Where does the name Thuringia come from?

A:
the Germanic tribe Thuringii
