VeritasKarishma GMATNinja Can we say option d is correct if E isn't there by saying Cost of lawsuits + cost of imitators= high advertising cost
No, we cannot say that. "If option (E) were not there, would (D) be correct" is not how CR works, at least not the official questions.
A singer sued an advertising company for using an imitator for his/her famous song and won.
Now advertising companies will not use imitators (else they will get sued)
Singers charge more than imitators.
Conclusion: Advertising costs will rise.
To conclude that advertising cost will rise, we need to assume that the advertisers will use famous songs (with their original singers). What if advertisers stop using famous songs? Then they will not have to pay a lot of money to the famous singers of those songs.
Hence, (E) is our assumption.
What is an assumption?
(A) Most people are unable to distinguish a famous singer rendition of a song from a good imitator's rendition of the same song.
Irrelevant to whether advertising costs will rise.
(B) Commercials using famous singers are usually more effective than commercials using imitators of famous singers.
Irrelevant to whether advertising costs will rise. This has impact on revenue generated through advertising but we are not discussing that at all. We are only talking about cost of advertising.
(C) The original versions of some well-known songs are unavailable for use in commercials.
Irrelevant.
(D) Advertising firms will continue to use imitators to mimic the physical mannerisms of famous singers.
We are told that advertising firms will not use imitators in commercials now.
Answer (E)
