What characterized the social rebellion and struggles for civil rights in the sixties and seventies?

If you had to choose a characterization of the social rebellion and struggles for civil rights in the sixties and seventies in the US, one option would be "peaceful," since although there were indeed some violent protests, most of them were remarkably non-violent--as those pursued by people like Martin Luther King Jr. 

Ithink it’s c , good luck on whatever : )
