Problem: The Demilitarized Zone runs northeast of the 38th parallel; to the south, it travels west. The old Korean capital city of Kaesong, site of the armistice negotiations, originally was in pre-war South Korea, but now is part of North Korea. The United Nations Command, supported by the United States, the North Korean People's Army, and the Chinese People's Volunteers, signed the Armistice Agreement on 27 July 1953 to end the fighting. The Armistice also called upon the governments of South Korea, North Korea, China and the United States to participate in continued peace talks. The war is considered to have ended at this point, even though there was no peace treaty. North Korea nevertheless claims that it won the Korean War.

Problem: Barcelona is the only European club to have played continental football every season since 1955, and one of three clubs to have never been relegated from La Liga, along with Athletic Bilbao and Real Madrid.

In the 201415 season, Barcelona won another historic treble, making them the first club in European football to win the treble twice.
When did Barcelona become the first Spanish team to win the treble competitions?

Problem: The development of flattop vessels produced the first large fleet ships. In 1918, HMS Argus became the world's first carrier capable of launching and recovering naval aircraft. As a result of the Washington Naval Treaty of 1922, which limited the construction of new heavy surface combat ships, most early aircraft carriers were conversions of ships that were laid down (or had served) as different ship types: cargo ships, cruisers, battlecruisers, or battleships. These conversions gave rise to the Lexington-class aircraft carriers (1927), Akagi and Courageous class. Specialist carrier evolution was well underway, with several navies ordering and building warships that were purposefully designed to function as aircraft carriers by the mid-1920s, resulting in the commissioning of ships such as Hosho (1922), HMS Hermes (1924), and Bearn (1927). During World War II, these ships would become known as fleet carriers.[citation needed]
What caused early aircraft carriers to be made up of conversions of ships that were previously cargo ships, cruisers or battlecruisers?
The answer is the following: Washington Naval Treaty of 1922
