Question

What paradox of social injustice is presented in these lines from Countee Cullen's “From the Dark Tower”?

We shall not always plant while others reap
The golden increment of bursting fruit,
Not always countenance, abject and mute
That lesser men should hold their brothers cheap;

A. The hearing and speaking impaired are routinely victimized by others in American society.
B .Degrading someone ultimately causes a person to become inferior to those they believe to be subordinate.
C . The natural system of justice is unbiased, and all people are given equal opportunity to grow and flourish.
D.Those who enforce racial segregation are typically isolated groups in society.

Answer 1

A & D are too specific and out of the scope of these lines

The key to answering this is in the last two lines
Consider some definitions
countenance - in this context, means calm or composed
abject - in this context, means off to the side
mute - silent
lesser - worse than or less important than
"holding someone cheap" = to look down on someone

with these definitions in mind, try to interpret what the last two lines are saying. this will help give you a clue as to what kind of general statement about social justice is being made
