Adults have the right to vote; so should adolescents. Admittedly, adolescents and adults are not the same. But to the extent that adolescents and adults are different, adults cannot be expected to represent the interests of adolescents. If adults cannot represent the interests of adolescents, then only by giving adolescents the vote will these interests be represented. The argument relies on which one of the following assumptions? ['The right to vote is a right that all human beings should have.', 'Adolescents and adults differ in most respects that are important.', 'Adolescents should have their interests represented.', 'Anyone who has the right to vote has all the rights an adult has.']
