Name one U.S. territory.

Puerto Rico is indeed a U.S. territory, making it a correct choice. It is one of the largest and most well-known territories, located in the Caribbean Sea. Puerto Rico has been a U.S. territory since 1898, following the Spanish-American War, and it has a unique political status that allows it to have its own constitution and a significant degree of self-governance, while still being under the jurisdiction of the United States. Citizens born in Puerto Rico are U.S. citizens, but Puerto Rico does not have voting representation in Congress, which highlights some of the complexities of its territorial status.

Other potential answers also represent U.S. territories, yet may not be as commonly recognized. Guam, American Samoa, and the U.S. Virgin Islands each have their own distinct histories and political relationships with the United States. While all of these locations function as U.S. territories, Puerto Rico's larger population and cultural significance often bring it to the forefront of discussions regarding U.S. territories.
