Name one U.S. territory.

Why this is the answer

Any one of five places answers this: Puerto Rico, the U.S. Virgin Islands, American Samoa, the Northern Mariana Islands or Guam. Say the name the way the official list writes it. A territory belongs to the United States without being a state. USCIS describes it as partially self-governing land under the authority of the federal government, and that authority comes from the Constitution itself. Article IV, Section 3 gives Congress the power to make all needful rules and regulations for territory belonging to the United States, and the same section is the one that lets Congress admit new states. The difference shows most clearly in Congress and at election time. Each territory sends a delegate to the House of Representatives, and USCIS's own answer notes describe these delegates and resident commissioners as nonvoting. Territories have no senators either; the official list tells residents asked to name their senator to say that their territory has none. Presidential elections are where the gap is widest. People in the territories can vote in presidential primaries but not in the general election, and the reason sits in Article II: the Constitution gives presidential electors to each State, and a territory is not one. Status is not uniform across the five. The people who live in American Samoa are considered U.S. nationals, while those in the other four territories are U.S. citizens. Hawaii is a tempting wrong answer, but it has been a state since 1959, when it became the 50th. Washington, D.C., is another miss: in those same answer notes USCIS handles the District as its own case, apart from the territories. Puerto Rico and Guam are the two names least likely to go wrong under pressure, because each is short and has nothing to add or leave out.
