It helps build their confidence
The correct answers should be C, B, and B. I hope these are correct for you. In paragraph 3 it says " 100 years later the Negro live on a lonely island". this means the answer is C for the first one. The second one is B because when he says chains of discrimination he does not mean their actually held by chains. This means B is the answer for the second one. In paragraph 8 it says that "The Negro lives on a lonely island of poverty". This means B is the correct answer for the third one. Hope this helped.
I would say connecting objects, hope this helps :)
