Explanation:

This is an incomplete question that can be answered in three different ways depending on the sentence you are referring to. All of the options come from Dr. Martin Luther King's "Letter from Birmingham Jail."

Sentence 1

Read the excerpt from Dr. Martin Luther King's "Letter from Birmingham Jail."

to emphasize the productivity of his daily routine

*to undermine the significance of his critics' letter

By using the if clause the author is stating the fact of answering to criticism as an unreal situation which undermines the importance he gives to what others think about his procedures.

Sentence 2

to explain the need for mutual understanding

to criticize people who treat others cruelly

The author mentions in these lines that it is more hurtful than a person who can be considered a "good" person does not get or understand you than to be rejected by a person who sees everything as negative and incorrect. Since the second situation is expected to be and should not be taken seriously.

Sentence 3
