Which of these states borders Mexico?

1. Four states border Mexico: California, New Mexico, Arizona, and Texas. 2. Arizona is one of them, so it is the answer. 3. Montana and Vermont both border Canada instead, which is the border on the other side of the country. 4. Georgia borders neither country, because it lies on the Atlantic coast. _Source: USCIS Civics Flash Cards M-623 (rev. 02/12), public domain, official civics question 93_
