S: People who are old enough to fight for their country are old enough to vote for the people who make decisions about war and peace. This government clearly regards 17 year olds as old enough to fight, so it should acknowledge their right to vote. T: Your argument is a good one only to the extent that fighting and voting are the same kind of activity. Fighting well requires strength, muscular coordination, and in a modern army instant and automatic response to orders. Performed responsibly, voting, unlike fighting, is essentially a deliberative activity requiring reasoning power and knowledge of both history and human nature. T responds to S's argument by
A: calling into question S's understanding of the concept of rights
B: arguing for a conclusion opposite to the one drawn by S
C: challenging the truth of a claim on which S's conclusion is based
D: showing that S has ignored the distinction between having a right to do something and having an obligation to do that thing
