Final answer:
The correct option is 1) fight for civil rights.
Louis joins the Freedom Riders to fight for civil rights, challenging segregation in interstate transportation in the South through nonviolent protest inspired by Enlightenment philosophy.
Step-by-step explanation:
Louis joins the Freedom Riders whose goal is to fight for civil rights. This mission is rooted in the history of the Civil Rights Movement which sought to end racial segregation and discrimination against African Americans.
Inspired by the nonviolent civil disobedience practiced by Mahatma Gandhi, the Freedom Riders, a mix of African American and White civil rights activists organized by the Congress of Racial Equality (CORE), embarked on bus rides throughout the southern United States in 1961. Their aim was to challenge and test the enforcement of a U.S. Supreme Court decision that prohibited segregation on interstate transportation, spotlighting the injustice of segregated waiting rooms in Southern terminals.
The activism of the Freedom Riders and other civil rights advocates was a direct reflection of the Enlightenment philosophy which emphasized that life, liberty, and the pursuit of happiness are God-given rights embedded in the Bill of Rights. The Freedom Riders' efforts, alongside other campaigns like the Mississippi Freedom Summer and the March on Washington, highlighted the urgency for societal change and played a crucial role in the broader Civil Rights Movement.
