What change did the Twentieth Amendment implement regarding presidential terms?

The Twentieth Amendment, ratified in 1933, shifted the inauguration date of the President and Vice President from March 4 to January 20. This change was implemented to reduce the "lame duck" period, which is the time between the election and the beginning of a new president's term. By moving the inauguration closer to the election date, the amendment aimed to enhance the efficiency of the government and ensure that newly elected officials could assume office sooner, thus allowing for a more timely response to national issues.

The other choices pertain to different historical amendments or legislative actions. Limiting presidential terms to one is not a provision of the Twentieth Amendment; instead, the Twenty-Second Amendment addresses presidential term limits. The removal of the direct election of senators relates to the Seventeenth Amendment, which established that senators would be elected directly by the public. Lastly, making alcohol legal directly pertains to the Twenty-first Amendment, which repealed Prohibition enacted by the Eighteenth Amendment. Each of these elements is significant in their own right, but they do not pertain to the changes brought about by the Twentieth Amendment.
