Which 1957 event involved federal troops enforcing desegregation at Central High School in Little Rock?

• A. Greensboro Four
• B. Little Rock Nine
• C. Montgomery Bus Boycott
• D. Freedom Rides

Answer: (B)

The key idea here is how the federal government stepped in to enforce desegregation in the face of local resistance, showing that Supreme Court rulings like Brown v. Board of Education could be backed up by federal action. In this 1957 incident, nine Black students known as the Little Rock Nine attempted to enter Central High School in Little Rock, Arkansas. Mobs and state authorities resisted their entry, but President Eisenhower ordered federal troops to enforce the desegregation order and protect the students as they attended classes. This use of federal troops to uphold a desegregation ruling is what defines the event.

The other options refer to different Civil Rights actions: the Greensboro Four were part of sit-ins in 1960, the Montgomery Bus Boycott occurred in 1955–56 over bus segregation, and the Freedom Rides began in 1961 challenging segregation on interstate buses.
