Answer:
The chief purpose of paragraph 2, sentences 1 through 2 is to
D. appeal to ethos
Step-by-step explanation:
Paragraph 2, sentences 1 through 2, appeals to ethos by establishing the credibility of Martin Luther King, Jr. to speak authoritatively on the subject under discussion. The two sentences balance the two sides of the argument about police conduct. Therefore, Martin Luther King, Jr. showed that he had the moral standing to speak about the happenings in Birmingham because he is fair (not biased) in his criticisms and accepts the right conducts of the police in public while deploring their conduct in private.
