What does the necessity of training in nonviolence indicate about the protestors' understanding of American society?

The correct answer to this open question is the following.

Although there are no options attached, we can say the following.

The necessity of training in nonviolence indicated about the protestors' understanding of American society that they knew that non-violent actions during their marches and protests would get to the American people's hearts and feelings, and this would create sympathy for the civil rights movement from white people across the country.

Civil rights activist leader Martin Luther King Jr was influenced by the non-violent demonstrations initiated by Indian leader Mahatma Gandhi in India, and the good results he had. So, Luther King tried to do the same with his demonstrations. And indeed, he received the support of black and white American citizens.
