The purpose of the first step of the amendment process is to propose an amendment. To understand this, you can refer to the Constitution of the United States, specifically Article V, which outlines the process for amending the Constitution. The first step involves proposing an amendment, which can be done in two ways: (1) by a two-thirds vote in both the House of Representatives and the Senate, or (2) by a constitutional convention called for by two-thirds of the state legislatures. Once an amendment is proposed, it does not become part of the Constitution immediately. It needs to go through additional steps, including ratification, to be officially added to the Constitution. So, the correct response is "To propose an amendment."
