In the Romeo and Juliette, this scene happen between Romeo and the Nurse.
Romeo say that his comfort has been Reviv'd after The nurses gives him a Ring which belong to Juliette. He perceive it as a sign of good gesture from her and he know that how she loved him
She says,"America is not broken (by rascism) but simply isnt finished". I think she means America needs to fix its self and by saying it isnt finished means that it's history is not over and can still be righted to not be rascist.
