The correct answer to this open question is the following.
The strategies that movement activists employed in their efforts to transform Albany, Birmingham, and the nation were the use of nonviolent marches, protests, and demonstrations such as taking the streets to demand civil rights for African Americans and other minorities. They also used litigation and sits-ins. People from all backgrounds, including students, participated in these demonstrations.
The resistance they met was the fact that many white people saw these demonstrations as a risk to the status quo, and demanded the police to stop the demonstrations and arrest the people that participated in those events. That is why, activist leaders like Dr. MartinLuther King, ended up in jail, in Birmingham jail, where he wrote his famous "Letter From Birmingham Jail."
