Name one U.S. territory.

Puerto Rico is indeed one of the U.S. territories. It became a U.S. territory in 1898 following the Spanish-American War and has since maintained a unique status, allowing its residents to exercise U.S. citizenship without the right to vote in federal elections. It has its own local government and constitution, which provides a degree of autonomy.

Each of the other choices listed also represents a U.S. territory, including the U.S. Virgin Islands, American Samoa, and Guam. However, Puerto Rico is often the most recognized and discussed territory, making it a common choice in such questions. Recognizing Puerto Rico as a U.S. territory is essential for understanding the broader concept of U.S. territories and their relationship with the federal government.
