How did the greensboro four contribute to the new resistance strategies of the civil rights movement?

The Greensboro Four contributed by using the sit-in method to incite social change.

Explanation:

The Greensboro Four refers to a group of four African American men who protested the segregation policy at a Woolworth's lunch counter during February of 1960. Initially, this started off as a small effort by these four to change the companies policy about refusing lunch service to African American citizens. However, after only a few days, hundreds of other colleged aged students joined in this sit-in movement.

This was an example of a nonviolent protest that African Americans used during the 1960's to incite change. These sit ins were then used in several different states all over the US. After roughly 6 months, the strategy was successful. Woolworth's reopened and allowed service to black and white citizens at their lunch counters.
