Final answer:
Mechanisms to keep Blacks from voting that are now illegal included poll taxes, literacy tests, and grandfather clauses.
Step-by-step explanation:
The mechanisms to keep Blacks from voting that are now illegal included poll taxes, literacy tests, and grandfather clauses. Poll taxes were special fees that had to be paid before voting, which was often beyond the financial reach of African Americans. Literacy tests required voters to pass a minimum standard of knowledge, and these tests were often more difficult for African Americans. Grandfather clauses exempted people from voting restrictions if they or their ancestors had previously voted, which did not apply to African Americans.
