• B. Till published a newspaper advocating nonviolence.
• C. Till's brutal lynching highlighted racial violence and spurred national outrage and activism.
• D. Till's case resulted in immediate federal civil rights legislation.

Answer: (C)

The event tests your understanding of what can spark a broad social movement: a brutal act of racial violence and the way it becomes impossible to ignore when it’s witnessed by a national audience. Emmett Till’s lynching in 1955, and the powerful open-casket funeral Mamie Till-Mobley arranged so the world would see what had happened, brought the reality of white-supremacist violence in the South straight into living rooms across the country. The stark photographs and reports of his murder exposed how the system tolerated or even protected such violence, which sparked widespread outrage and galvanized both Black communities and White allies to organize, protest, and demand change. That surge of moral energy helped fuel the Montgomery Bus Boycott and a broader push for nonviolent resistance, leadership from civil rights organizations, and a push for federal action, even as true legislative changes took more time to come. So this event is the one that best explains why the Civil Rights Movement gained urgent momentum—by making racial violence visible and generating sustained activism in response.
