Name one U.S. territory.

Guam is a U.S. territory, specifically a part of the unincorporated territories of the United States. It is located in the Western Pacific Ocean and is known for its strategic military base and unique cultural mix influenced by Chamorro, American, and other cultures. Unlike the other options provided, which are states or commonwealths, Guam is an area that is under U.S. jurisdiction but does not have the same status as the 50 states. Residents of Guam are U.S. citizens; however, they do not have the right to vote in presidential elections and have a non-voting delegate in the U.S. House of Representatives. This defines the difference in status and rights when compared to states like Alaska, Pennsylvania, and New Mexico, all of which are fully recognized U.S. states with representation in Congress and voting rights in federal elections.
