Answer:
The right answers are:
A honor the Union soldiers and their bravery throughout the Civil War.
C remind Americans of the reasons that the Civil War was being fought.
Explanation:
In one phrase, Abraham Lincoln said, "The brave men, living and dead, who fought here." So, he is honoring the Union soldiers and their bravery.
In another phrase, Lincoln says, " 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." So, he reminds the American people of the reasons why the war is being fought. He also points that "these dead shall not have died in vain."
