Read Lincoln’s statement from "The Gettysburg Address." Four score and seven years ago, our fathers brought forth upon this continent a new nation: conceived in liberty, and dedicated to the proposition that all men are created equal.

In this excerpt, Lincoln uses brevity to make an emotional impact

by discussing what freedom meant to the founding fathers.
by reminding people that the country was not founded that long ago.
by discussing how the founding fathers developed the country.
by making a clear point that the country was founded upon equality for all. Explain how Whitman develops an extended metaphor in his poem.
