Which of these is a national U.S. holiday?

1. The national U.S. holidays are New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Memorial Day, Independence Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving, and Christmas. 2. Veterans Day is on that list, so it is a national holiday. 3. Election Day is the day people vote in November, and it is not on the list of national holidays. 4. Mother's Day is widely marked but is not one of the national holidays either. 5. Founders Day is not on the list at all. 6. The trap is that all four sound like holidays, so only the official list decides. _Source: USCIS Civics Flash Cards M-623 (rev. 02/12), public domain, official civics question 100_
