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.

abraham lincoln was the president of usa and he had asked the audience to make a pledge on equality.

his pledge was:

“it is my earnest desire to know the will of the providence.”

lincoln also had hatred for people who condoned and practiced slavery and so he pledged:

""and if i can learnt what it is i can do it"" this is another pledge by abraham to reassure the congregation on how to deal with the providence will.
