What is the purpose of evidence in an argument? A. to identify how the author's reasons relate to the claim
B. to state the writer's main point and what he or she wants to accomplish
C. to support the author's reasons for his or her claim
D. to appeal to the audience's emotions, logic, and ethics

A. to identify how the author's reasons relate to the claim

Explanation:

By using strong citations, the claim that the author may be supporting can be backed up. Let's say they are running a campaign against laboratory animal testing, and they have no evidence- people will not be interested in their claim, not will they have anything to back up their point.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
