Question

read lincolns 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 founders.
by reminding people that the country was not founded that long ago.
by discussing how the founders developed the country.
by making a clear point that the country was founded upon equality for all.

Explanation:

Lincoln's statement emphasizes the nation's founding principles. The key point is about the foundation of the country. Discussing freedom for founders (first option) is too narrow. Saying the country wasn't founded long ago (second option) is incorrect as "four score and seven years" (87 years) is a reference but not the main emotional impact. Discussing how founders developed the country (third option) is not the main focus. The statement clearly highlights that the country was founded on equality ("dedicated to the proposition that all men are created equal"), which is a strong emotional and ideological point.

Answer:

by making a clear point that the country was founded upon equality for all.
