The correct answer is: "the rise of Stokely Carmichael to leader of the SNCC".
The acronym SNCC stands for Student Nonviolent Coordinating Committee, which was one of the main organization that arose during the Civil Rights Movement in the decade of the 1960s. It was originated after the wave of sit-in performed by students. IT was an institution with a direct implication in transforming the communities and their organization. For example, they coordinated voter registration or freedom schools for African Americans.
In the later 1960s, the arrival of more fierce leaders such as Stokely Carmichael meant a shift in the strategy of the organization, that even changed its name to Student National Coordinating Committee, to make clear in which aspects they had changed.
