Step-by-step explanation:
The society that formed at PSC Lyceum and eventually merged with NCM was the NAACP (National Association for the Advancement of Colored People). The NAACP was formed in 1910 with one of its objectives being a scientific study of Black schools and the formation of a national committee to study the question of national aid for education. Led by Charles H. Houston, lawyers associated with the NAACP filed lawsuits against graduate and professional schools that excluded Black students. Ultimately, the NAACP played a crucial role in the civil rights movement, challenging segregation and discrimination and making significant progress in advancing the rights of African Americans.
