Prior to 1950, the NAACP focused its legal efforts on which issue?

Before 1950, the NAACP pursued a strategy of challenging segregation through specific lawsuits, especially in graduate and professional schools. These cases exposed the inequality of “separate but equal” and helped build the legal groundwork for Brown v. Board of Education. The correct choice is ending segregation in public graduate and professional schools; the NAACP did not initially focus on directly overturning Plessy v. Ferguson itself.
