Question

in the early 1900s, the national association for the advancement of colored people strongly urged the federal government to
punish lynch mobs.
overturn jim crow laws.
limit integration.
limit activist organizations.

Explanation:

The NAACP was founded to fight for the rights of African - Americans. Lynching was a violent and illegal act against African - Americans. The NAACP would advocate for the punishment of those who carried out such heinous acts. Jim Crow laws were overturned later through a series of court cases and civil rights movements, not a direct early - 1900s NAACP demand in this context. The NAACP was in favor of integration, not limiting it. And it was an activist organization itself, so it would not limit activist organizations.

Answer:

punish lynch mobs.
