and goldenseal. A cold sufferer, skeptical of the
claim that the mixture is an effective cold remedy, argued,
тАЬSuppose that the mixture were an effective cold remedy.
Since most people with colds wish to recover quickly, it
follows that almost everybody with a cold would be using
it. Therefore, since there are many people who have colds
but do not use the mixture, it is obviously not effective.тАЭ

the method of reasoning the cold sufferer uses to
reach the conclusion of the argument?

of the claim
(C) showing that conditions necessary to establish
the truth of a claim are met
(D) basing a generalization on a representative
group of instances
