Read the excerpt from martin luther king jr.’s "i have a dream” speech.
but one hundred years later, the negro still is not free. one hundred years later, the life of the negro is still sadly crippled by the manacles of segregation and the chains of discrimination. one hundred years later, the negro lives on a lonely island of poverty in the midst of a vast ocean of material prosperity.
how does the repeated phrase support king’s message?
by emphasizing that time has passed without social progress
by suggesting that freedom will come eventually without effort
by insisting that people cooperate to achieve a common goal
by hinting that all americans should strive for material wealth

A

Explanation:

The first answer is the only answer. This parallel construction emphasizes that time has passed; no progress has been made. Look at the language. Read it carefully. Phrases like sadly crippled by the manacles of segregation and the chains of discrimination. Does this sound like there is anything that has moved forward when the language suggests that nothing has occurred since 1861.

Another example ... lives on lonely island of poverty in the midst of a vast ocean of material prosperity. The poetry reflects and states while one segment of society has become rich, the other segment has not. Nothing has been gained.

B: Where does it even hint at B? Where does it say that the freedom is effortless?  Nowhere. Not B.

C: He doesn't advocate any common goal, not in this section. The purpose of this message is to point out that the colored have been short changed.

D: Again, he does not ask that the colored should strive for wealth. He wants change, not easily obtained wealth. Not D.
