Aided by Great Society legislation, which movement reached its height under President Johnson?

Civil Rights Movement

Environmental Movement

Organized Labor

Movement Anti-War Movement

The correct answer should be the Civil Rights Movement.

After all, it was under President Johnson that the Civil Rights Act and all that followed it was passed. It enabled not only people of color to vote, but also minorities and people who sometimes didn't even know the language. It was a major victory for human rights.
