Final Answer:
The most celebrated sit-in during the '60s occurred in Greensboro, NC. This conclusion is based on historical records and the widespread recognition of the Greensboro sit-ins as a pivotal moment in the civil rights movement. Therefore, the correct answer is 1) Greensboro, NC.
Step-by-step explanation:
The Greensboro sit-ins, initiated on February 1, 1960, at the Woolworth's lunch counter, marked a significant turning point in the struggle for civil rights. The event was sparked by four African American college students, known as the "Greensboro Four," who peacefully protested against racial segregation by sitting at the whites-only lunch counter.
The sit-ins quickly gained momentum, inspiring similar protests across the country and leading to the formation of the Student Nonviolent Coordinating Committee (SNCC). The sit-ins in Greensboro were instrumental in challenging discriminatory practices and fostering a spirit of resistance that became a hallmark of the civil rights movement.
In contrast, while Selma, Montgomery, and Birmingham were also key locations for civil rights activism in the '60s, they are more commonly associated with other significant events. Selma is renowned for the Selma to Montgomery marches in 1965, Montgomery for the Montgomery Bus Boycott that began in 1955, and Birmingham for events like the Birmingham campaign in 1963. However, the Greensboro sit-ins stand out as a symbol of grassroots activism and nonviolent resistance during the early '60s, making Greensboro, NC, the most celebrated sit-in location of that era.
Therefore, the correct answer is 1) Greensboro, NC.
