Here are the descriptions organized by the correct form of segregation:
1. Social Segregation (Dining)
- Black customers were not served; students staged sit-ins to protest unfair serving practices.
2. Transportation Segregation (Bus Rides)
- People of different races had to sit in different areas; the Freedom Riders protested these rules.
3. Political Segregation (Voting)
- Intimidation and violence toward different races was common; Student Nonviolent Coordinating Committee (SNCC) worked to register black people.
