QS: Role.
Argument:
Few politicians will support legislation that conflicts with their own self-interest. --> Principle.
A case in point is August Frenson, who throughout his eight terms in office consistently opposed measures limiting the advantage incumbents enjoy over their challengers. ---> An example.
if such measures are to be enacted---> premise.
they must result from direct popular vote rather from legislative action.---> Conclusion.
(A) It provides evidence, the falsity of which would guarantee the falsity of the author’s conclusion. (Example is sufficient for the conclusion? No, OUT.
(B) It is cited as an example illustrating the generalization that is invoked. ---> Few politicians= August Frenson? Like in the argument.
(C) It gives essential background information concerning a measure being advocated.----> Nope, it is not a principle.
(D) It demonstrates the extent to which incumbents have the advantage over challengers.---> Nothing about the extent is given in the argument. So OUT.
(E) It gives an example of the limits of direct popular vote.----> Nope, but it may be about the limits of legislation. So OUT.
