I think it was the:
Civil Rights Act
The Civil Rights Act of 1957 was passed in order to make sure that all
Americans could exercise their right to vote. It was the first civil
rights legislation passed since reconstruction. Its enactment also came after African Americans were increasingly targeted with violence following the U.S. Supreme Court’s Brown v. Board of Education decision ending segregation in schools. The law showed a renewed national attention to
guaranteeing civil rights to all Americans. In addition, it established the Commission on Civil Rights, a federal oversight committee that examined opinions of the public and state laws regarding civil rights.
They were beiing mean people.
Its C I believe.
Hope it helps
