Answer:
To help desegregate public schools and advance the cause of civil rights.
Step-by-step explanation:
Minnijean Brown enrolled in Central High School in Little Rock, Arkansas in 1957 as part of a group of nine African American students known as the "Little Rock Nine." They were the first black students to attend the previously all-white school, following the landmark Supreme Court case Brown v. Board of Education of Topeka in 1954, which ruled that segregation in public schools was unconstitutional.
Minnijean Brown, like the other members of the Little Rock Nine, enrolled in Central High School to help desegregate public schools and advance the cause of civil rights. Their enrollment was met with strong opposition from white segregationist groups, who organized protests and even violence against the students. Despite these challenges, the Little Rock Nine persisted and helped to pave the way for greater integration and equality in American society.
