Final answer:
The growing popularity of Malcolm X, Black Panthers, and the impatience with Martin Luther King Jr.'s methods indicated a shift towards a more assertive approach in the Civil Rights Movement. 'Bloody Sunday' in Selma was the pivotal event that helped President Johnson garner support for the Voting Rights Act. The correct answer is option d.
Step-by-step explanation:
The increasing popularity of Malcolm X, the growth of the Black Panther Party, and the impatience within the African American community regarding the cautious approach of Martin Luther King Jr. all highlighted a shift within the Civil Rights Movement by 1965. This shift indicated that many African Americans had become impatient with King's cautious approach (Option D), seeking a faster and more assertive path towards racial equality and justice.
The event that gave President Johnson the support he needed to push for the passage of the Voting Rights Act was the "Bloody Sunday" in Selma. The violent reactions of local and state authorities to peaceful marchers on the Edmund Pettus Bridge galvanized national attention and support for comprehensive voting rights legislation.
Through these various movements and the strength of community action, significant changes such as the Civil Rights Act of 1964 and the Voting Rights Act of 1965 were enacted, which began dismantling systemic racism and empowering African Americans.
