Answer: C. Both expressed impatience with the slow progress of civil rights
Step-by-step explanation:
In his, I Have a Dream speech, given in a rally in Washington to request approval of Kennedy's civil rights bill, King wishes for a future without racial discrimination.
His Letter from Birmingham Jail was his response to the white clergymen that deemed him unwise and untimely following his arrest for taking part in a non-violent march protesting segregation. King dreads the lack of support offered by Christians that didn't protest against racism.
