Answer:
The efect achieved by using a series of questions in this speech is B. It gets the audience to start thinking about whether the Declaration of Independence was beneficial for the slaves.
Step-by-step explanation:
The excerpt we are studying here was taken from a speech given by Frederick Douglass when he was invited to talk at a Fourth of July celebration. Douglass (1818 - 1895), a former slave, uses a series of questions in the speech as a strategy to make his audience reflect on the real issue at hand: slavery. Even though America is celebrating its freedom from England, Douglass thinks of such freedom as an illusion, a lie. How can America rejoice and sing of being free when it holds slaves? How can slaves partake in the celebration when they are kept as other people's property? Douglass intends to have people ponder over their own hypocrisy.
