The given statement discusses a lawsuit where a famous singer won against an advertising firm for using another singer in a commercial to evoke the famous singer's rendition of a certain song. It concludes that advertising firms will stop using imitators in commercials, and as a result, advertising costs will rise since famous singers' services cost more than those of their imitators. Let's evaluate each option to determine which assumption supports the conclusion:
(A) Most people are unable to distinguish a famous singer's rendition of a song from a good imitator's rendition of the same song.
This assumption does not directly support the conclusion. While it introduces the idea that people might have difficulty distinguishing between a famous singer and a good imitator, it does not establish a link to advertising firms stopping the use of imitators or the rise in advertising costs.
(B) Commercials using famous singers are usually more effective than commercials using imitators of famous singers.
This assumption supports the conclusion. If commercials using famous singers are generally more effective than commercials using imitators, it provides a reason for advertising firms to stop using imitators. As a result, they would need to hire famous singers instead, leading to higher advertising costs.
(C) The original versions of some well-known songs are unavailable for use in commercials.
This assumption is unrelated to the conclusion. While it discusses the availability of original versions of well-known songs, it does not provide any direct connection to advertising firms using imitators or the rise in advertising costs.
(D) Advertising firms will continue to use imitators to mimic the physical mannerisms of famous singers.
This assumption weakens the conclusion. If advertising firms continue to use imitators to mimic the physical mannerisms of famous singers, it undermines the claim that advertising firms will stop using imitators altogether. This suggests that the rise in advertising costs due to hiring famous singers may not be a certain outcome.
(E) The advertising industry will use well-known renditions of songs in commercials.
This assumption supports the conclusion. If the advertising industry is expected to use well-known renditions of songs in commercials, it strengthens the claim that advertising firms will need to hire famous singers instead of imitators. This supports the conclusion that advertising costs will rise due to the higher expenses associated with hiring famous singers.
The conclusion provided in the statement is based on the assumption that the advertising industry will use well-known renditions of songs in commercials (option E). This assumption supports the claim that advertising firms will stop using imitators and hire famous singers instead, leading to higher advertising costs. The other options either do not support the conclusion or introduce conflicting assumptions.
