Translation:Is America a continent?
The English translation should read "Is the United States a continent?"
미국 refers to the United States. As most people know, while "America" is commonly used in English to refer to the U. S., that's confusing here, since it's also the name of the continents. In Korean, 미주 refers to the American continents.
Not so simple in English and in some other languages. "America" usually means the U.S., where North America and South America are considered two continents (the Americas). "Americans" almost always means people from the U.S., although "Native Americans" is a term used in the U.S. to refer to the various indigenous peoples of the Americas, especially the U.S. Even British people call the U.S. "America." People from Latin America often complain about how English is used outside of their own countries and are surely unaware that there are other languages that refer to the U.S. and its people as "America" and "American."
