- The suitable answer which best describes the amendment process is: "It is an intentionally difficult process in which an amendment must be proposed and approved by 2/3 of Congress or 2/3 of the state legislative before being ratified by 3 fourths of the States.
- A more detailed explantion for the amendment process would be the following:
The Constitution of the United States, more precisely, the Article V of the Constitution, states that an amendment may be proposed by the Congress with a two-thirds majority vote in both the House of Representatives and the Senate or by a constitutional convention called for by two-thirds of the State legislatures.
After that, the original document is sent to NARA's Office of the Federal Register (OFR). The latter examines ratification documents for facial legal sufficiency as well as an authenticating signature.
A proposed amendment becomes part of the Costitution the moment in which it is ratified by three-fourths of the States. Then, the OFR validates the required ratification documents and it drafts a formal proclamation to the Archivist, who immediately conveys a certified copy of the State action to the Director of the Federal Register so as to certify the amendment is valid.
Last but not least, this certification is published in the Federal Register and the U.S. Statutes at Large and it functions as the official notice to the Congress that the amendment process has been finished.
