The correct answer to this open question is the following.
The ways in that student voices advanced the movement for civil rights was notable because college students had the wit and the courage to form CORE, Congress for Racial Equity, in 1942. If we focus on the ideas prevalent in that time and the way American society thought about expressing its opinions in public, we acknowledge the courage those college students had. Something similar happened 18 years later in 1960 when college students formed the SNCC, the Student Nonviolent Coordinating Committee, another civil rights organization that used nonviolent methods to protest, just like CORE.
The ways might college-aged students’ perspectives have been limited are that sometimes government officials did not pay attention to their demands for considering them young people, "unaware" of how things are in the real life. The government let them express but not always take them seriously. That is why -in the case of CORE and SNCC- they started as a nonviolent group, but when they realized that no serious progress was done through their nonviolent demonstrations, many of them became part of the Black Power movement that sometimes used violence as part of their demonstrations.
