32. Read the arguments given below and answer the questions that follow.
A famous signer recently won a lawsuit against an advertising firm for using another singer in a commercial to evoke the famous singer’s well known rendition of a certain song. As a result of the lawsuit, advertising firms will stop using imitators in commercials. Therefore, adverting costs will rise, since famous singers’ services cost more than those of their imitators.
The conclusion above is based on which of the following assumptions?
If (c) were not assumed, the cost of the services of the famous singers of well-known renditions of songs would not be said to affect advertising costs. Since advertising costs are, however, projected to rise because of the relatively high cost of famous singers’ services, (c) is assumed and is the best answer.
Choice (a) is irrelevant to the argument, since famous singers’ services cost more than imitators’ anyway. The argument addresses commercials’ cost, not their effectiveness, so (b) is not assumed. Since the argument states that advertising firms will stop using imitators, (d) is not assumed.
