The Gettysburg Address shows Lincoln’s determination to have a unified country once more. What sentence from the speech best supports this conclusion?

"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."

"It is rather for us to be here dedicated to the great task remaining before us...and that government of the people, by the people, and for the people, shall not perish from the earth."

"Now we are engaged in a great civil war, testing whether that nation or any nation so conceived and so dedicated, can long endure."

"It is for us the living, rather, to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced."

"It is for us the living, rather, to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced."  As the unfinished work was to reunite the nation, this is the correct answer.

Explanation:

The Gettysburg Address is a speech by President Abraham Lincoln delivered on November 19, 1863 at the inauguration of Soldier's National Cemetery in Gettysburg, Pennsylvania.  

In his short speech, Lincoln attempted to summarize why the speakers and audience were together that day. He spoke of the reason behind the emergence of the young republic of the United States and why a terrible war was now tearing the republic in two. And why the people buried in that cemetery had made their sacrifice.

Lincoln's short and simple speech is considered the most elegant and beautiful summary of the Civil War - the reason why it was fought, the higher purpose behind all the misery it brought, the motives of all American society at the time.
