The correct answer to this open question is the following.
Although there are no options for this question we can say the following.
Where did the civil rights movement shift its focus after the passage of the Civil Rights Act?
We can say that after Congress passed the Civil Rights Act, the movement focused on improving the right to vote of the black people in the southern states.
Today we know that in the South, during Reconstruction, the Civil Rights Act of 1875 was rarely enforced.
The Civil Rights Act was approved in March 1875. The Act granted rights to African Americans and prohibited any kind of racial discrimination in public places such as restaurants, hotels, and public transportation. But during Reconstruction, the Southern states did not enforce the mandate of the Act. Many people living in the Southern states did not accept the desegregation laws and still supported slavery. So they kept on being racist and applying segregational conducts.
