Which textual evidence supports Lincoln's purpose in writing this speech? Question 2 options: "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 battle-field of that war." "We have come to dedicate a portion of that field, as a final resting place for those who here gave their lives that that nation might live." All of the above

I believe the third option is the best one:

"We have come to dedicate a portion of that field, as a final resting place for those who here gave their lives that that nation might live."

Explanation:

The excerpts in the question were taken from Abraham's Lincoln famous speech known as the Gettysburg Address. Even though it was short speech, it entered history as beautifully structured and incredibly inspiring. The main purpose of the speech was to honor the soldiers who died in the Civil War by dedicating a piece of land to them. From that one, other purposes were derived such as to inspire people to keep on fighting to prevent their country from being divided. The excerpts among which we have to choose do not work as evidence with the exception of the third one. It is the only excerpt that makes it clear that the purpose of that moment is to honor the fallen soldiers.
