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.

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. What is the main purpose of this speech? (5 points)
