The Twenty-First Amendment is known for repealing what?

The Twenty-First Amendment to the United States Constitution is significant because it repealed the Eighteenth Amendment, which established Prohibition. Prohibition was a nationwide constitutional ban on the production, importation, transportation, and sale of alcoholic beverages, which was in effect from 1920 until 1933. The Eighteenth Amendment aimed to reduce crime and corruption, but it ultimately led to the opposite effect, with the rise of illegal speakeasies and organized crime related to the alcohol trade.

By enacting the Twenty-First Amendment in 1933, the U.S. government acknowledged the failures of Prohibition and restored the legal status of alcohol. This amendment reflects a pivotal shift in public opinion and government policy regarding alcohol consumption, recognizing that regulation rather than outright prohibition could be a more effective approach.

The other options pertain to different historical amendments that are unrelated to the Twenty-First Amendment: income tax was established by the Sixteenth Amendment, women's voting rights were secured by the Nineteenth Amendment, and the direct election of senators was mandated by the Seventeenth Amendment. Each of these amendments addresses significant aspects of U.S. governance and civil rights, but they do not pertain to the repeal of Prohibition.
