Final answer:
The Eighteenth Amendment and the Volstead Act prohibited the production, transportation, and sale of alcoholic beverages with alcohol content above 0.5 percent.
Step-by-step explanation:
The Eighteenth Amendment to the United States Constitution, also known as Prohibition, empowered Congress to pass laws banning the production, transportation, and sale of alcoholic beverages for beverage purposes. The Volstead Act, passed in 1919, outlawed the production of any beverage with an alcohol content higher than 0.5 percent. Violators of the Volstead Act faced penalties, although fines did little to deter those willing to break the law.
