Answer: The paragraphs make an emotional plea to the audience to honor King's legacy by avoiding violence.
Explanation:
The question refers to "RFK’s Speech Following the Death of MLK" (1968) by Senator Robert F. Kennedy.
In paragraphs 3-4, Kennedy acknowledges how angered African Americans must feel because of Martin Luther King´s assassination. Given that it was most likely a hate crime committed by a white person, the then-Senator claims to understand their justifiable desire of revenge and violence seeming like the only option. However, he pleas for them and all the American people to honor King's legacy by avoiding violence, as his life effort was to gain rights through peaceful protest.
