the volstead act banned the sale of alcohol in additional states proposed by congress.

the volstead act provided for the enforcement of the eighteenth amendment.
the volstead act governed the sale of alcohol in states omitted from the eighteenth amendmen

Explanation:

The Eighteenth Amendment prohibited the manufacture, sale, and transportation of intoxicating liquors. The Volstead Act was passed to define what constituted intoxicating liquors under the amendment and to provide a mechanism for its enforcement. It was not about banning in additional states (the amendment was nationwide), nor did it prohibit drinking (only manufacturing, sale, and transportation). And it wasn't about states omitted from the amendment as the amendment applied to all states.

Answer:

The Volstead Act provided for the enforcement of the Eighteenth Amendment.
