Problem: Arena Football League:

In 1993, the league staged its first All-Star Game in Des Moines, Iowa, the future home of the long-running Iowa Barnstormers, as a fundraiser for flood victims in the area. The National Conference defeated the American Conference 6440 in front of a crowd of 7,189. The second Allstar game was in Oct. 2013, with two games, the first in Honolulu, Hawai'i, the second being in Beijing, China.

In what city and state did the 1993 All-Star Game occur?
---
A: Des Moines, Iowa

Problem: Time:

Greenwich Mean Time (GMT) is an older standard, adopted starting with British railways in 1847. Using telescopes instead of atomic clocks, GMT was calibrated to the mean solar time at the Royal Observatory, Greenwich in the UK. Universal Time (UT) is the modern term for the international telescope-based system, adopted to replace "Greenwich Mean Time" in 1928 by the International Astronomical Union. Observations at the Greenwich Observatory itself ceased in 1954, though the location is still used as the basis for the coordinate system. Because the rotational period of Earth is not perfectly constant, the duration of a second would vary if calibrated to a telescope-based standard like GMT or UTin which a second was defined as a fraction of a day or year. The terms "GMT" and "Greenwich Mean Time" are sometimes used informally to refer to UT or UTC.

What did Greenwich Mean Time replace in 1847?

A: unanswerable

Problem: Tristan da Cunha:

The 1961 eruption of Queen Mary's Peak forced the evacuation of the entire population via Cape Town to England. The following year a Royal Society expedition went to the islands to assess the damage, and reported that the settlement of Edinburgh of the Seven Seas had been only marginally affected. Most families returned in 1963.

Which eruption caused the population of Royal Society to evacuate to England?
---
A: unanswerable

Problem: Aircraft carrier:

The constraints of constructing a flight deck affect the role of a given carrier strongly, as they influence the weight, type, and configuration of the aircraft that may be launched. For example, assisted launch mechanisms are used primarily for heavy aircraft, especially those loaded with air-to-ground weapons. CATOBAR is most commonly used on USN supercarriers as it allows the deployment of heavy jets with full loadouts, especially on ground-attack missions. STOVL is used by other navies because it is cheaper to operate and still provides good deployment capability for fighter aircraft.

Why is STOVL not used by other navies?
