Answer:
The best answer to the question: To what event does Lincol refer in this passage, would be: The American Revolution.
Explanation:
The Gettysburg Address was a speech that was delivered by U.S President Abraham Lincoln in 1863, in Gettysburg, Pennsylvania, during a dedication at the Soldier´s National Cemetery. This address happened during the Civil War, exactly a few months after the Union Army was finally able to defeat the Confederate Army at the Battle of Gettysburg. The speech, which initiates with the words "Four score and seven years ago.." mentions not just the milestone of the Declaration of Independence, but also, the American Revolution, through which "our fathers brought forth on this continent a new nation, conceived in Liberty, and dedicated to the proposition that all men are created equal.". This is why the best answer from the choices is the second one.
