Read this excerpt from abraham lincoln's gettysburg address and then answer the question that follows:

(1) 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.

now we are engaged in a great civil war … testing whether that nation, or any nation so conceived and so dedicated … can long endure. we are met on a great battlefield of that war.

(2) we have come to dedicate a portion of that field as a final resting place for those who here gave their lives that this nation might live. it is altogether fitting and proper that we should do this. but, in a larger sense, we cannot dedicate … we cannot consecrate … we cannot hallow this ground. the brave men, living and dead, who struggled here have consecrated it, far above our poor power to add or detract. the world will little note, nor long remember, what we say here, but it can never forget what they did here.

pay close attention to the word choice in this speech. the speaker is mainly concerned with convincing which of these groups of people of the correctness of his viewpoint?

people who reside in other countries with civil wars
people who have fought or lost loved ones in this battle
potential political allies for future election campaigns
residents of the area who could see the battle from home
