Final answer:
A poll tax is a fee charged to individuals to vote, and the Twenty-Fourth Amendment eliminated poll taxes in federal elections.
Step-by-step explanation:
A poll tax is a fee that was charged to individuals in order to vote in elections. This practice was used as a way to discourage certain groups, particularly African Americans, from exercising their right to vote. The Twenty-Fourth Amendment to the United States Constitution eliminated poll taxes in federal elections, making it illegal to require citizens to pay a fee in order to vote in national elections.
