Which group took bus trips through southern states in 1961 to protest illegal bus segregation?

• A. Civil Rights Act of 1964
• B. Montgomery Bus Boycott
• C. Little Rock Nine
• D. Freedom Riders

Answer: (D)

This question tests understanding of organized, nonviolent protest aimed at desegregating interstate travel in the early Civil Rights Movement. In 1961, a group of activists formed the Freedom Riders to ride buses through southern states to challenge illegal bus segregation in terminals and on routes that crossed state lines. They deliberately tested the enforcement of Supreme Court rulings and federal laws that had declared segregation on interstate travel unconstitutional. Their journeys brought violent backlash in some places, which drew national attention and led to federal intervention—U.S. marshals and federal officials stepped in to enforce desegregation and ensure the riders’ safety. The core idea is showing how nonviolent direct action, targeted at transportation desegregation, helped push federal enforcement and advance civil rights.

For context, the other options refer to different elements of the era: a piece of legislation passed several years later, not a protest group; a boycott aimed at desegregation in a single city earlier on; and a school desegregation event from the 1950s. The group described here specifically matches the 1961 interstate bus rides.
