Question

after the passage of the civil rights act, civil rights activists wanted to
overturn the fifteenth amendment.
overturn the twenty - fourth amendment.
elect john f. kennedy.
improve voting rights in the south.

Explanation:

The Civil Rights Act (1964) addressed segregation but voting barriers (like literacy tests, poll taxes) still disenfranchised Black Southerners. The 15th and 24th Amendments protected voting rights, so activists did not seek to overturn them. JFK died in 1963, before the Act's passage. Activists focused on fixing remaining voting access issues in the South, leading to the Voting Rights Act of 1965.

Answer:

improve voting rights in the South.
