Quote:
A famous singer recently won a lawsuit against an advertising firm for using another singer in a commercial to evoke the famous singer well-known rendition of a certain song. As a result of the lawsuit, advertising firms will stop using imitators in commercials. Therefore, advertising 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?
Conclusion: Advertising costs will rise
why? Because famous singers' services cost more than those of their imitators.
There itself is a gap in the argument.The author assumes that if the advertisers will stop using imitators, then they will be using the services of famous singers(Costlier) instead of some other cheaper alternative. So, our assumption will be along those lines.
Quote:
(A) Most people are unable to distinguish a famous singer rendition of a song from a good imitator's rendition of the same song.
It does not matter if most people cannot differentiate. If atleast one person differentiates, then there is probability of lawsuit. In addition, this option is not talking about cost implications.
Quote:
(B) Commercials using famous singers are usually more effective than commercials using imitators of famous singers.
The effectiveness of famous singers/Imitators is out of scope.It is the cost implication of these singers that matters.
Quote:
(C) The original versions of some well-known songs are unavailable for use in commercials.
The availability is out of scope. Even if they are available, there is no information provided to conclude that the advertisers will use these original versions.
Quote:
(D) Advertising firms will continue to use imitators to mimic the physical mannerisms of famous singers.
Imitation of physical mannerisms of famous singers is out of scope.
Quote:
(E) The advertising industry will use well-known renditions of songs in commercials.
This matches with our prethinking. Instead of going for some other alternative, Advertisers will use well-known renditions of songs in commercials.
