In this question, we are not given the necessary options in order to reply fully. However, we can still talk about the reasons why civil rights organizer Charles McLaurin decided to embrace the opportunity of the "Freedom Summer." This will allow you to answer the question on your own.
Initially, Charles McLaurin did not think that the idea of the "Freedom Summer" was a good one. Under this scheme, northern students (predominantly white) would travel to the South and help black Americans become registered voters. However, he eventually came around. There were several reasons for this. The most important one was the fact that McLaurin realized that students made particularly eager canvassers. Moreover, he understood that these students could form cores around which older African Americans could rally. Finally, he also became convinced that the presence of the students would bring a different perspective and an alternative view to the black communities of Mississippi.
