Final answer:
The 24th Amendment and the Voting Rights Act of 1965 protected and expanded voting rights for minority groups, particularly African Americans.
Step-by-step explanation:
The major result of the 24th Amendment and the Voting Rights Act of 1965 was the protection and expansion of voting rights for minority groups, specifically African Americans.
The 24th Amendment abolished poll taxes, which were used to disenfranchise minority voters. The Voting Rights Act of 1965 prohibited state laws that denied voting rights based on race and allowed federal examiners to monitor voter registration and elections in areas with a history of discrimination.
These measures led to a rapid increase in Black voter registration rates and played a significant role in promoting equality and civil rights in the United States.
