Final answer:
Following the sit-ins at lunch counters, the civil rights movement gained momentum, leading to the formation of the Student Nonviolent Coordinating Committee (SNCC), which spurred various other nonviolent protests and resulted in desegregation efforts across the country.
Step-by-step explanation:
After the sit-ins at Tallahassee lunch counters, a great momentum in the Civil Rights movement was inspired. The Greensboro sit-in protest sparked a surge of sit-in protests at public places across the country, with tens of thousands participating. This led to the formation of the Student Nonviolent Coordinating Committee (SNCC) in April 1960. SNCC played a crucial role in civil rights activism and helped desegregate public spaces by organizing various forms of nonviolent protest, including 'sleep-ins,' 'read-ins,' and 'pray-ins.' As a result of the sit-in movement's success, public accommodations began to desegregate in cities nationwide.
