Hello GMATNinja,GMATNinjaTwo,
Can you please suggest if my approach to eliminate option C is right.
My approach to the above problems:
Crux of argument:Advertising firms cost will rise because of hiring famous singers and not using imitators.
What to think before POE: What else must be true for the above conclusion to be valid..
(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. Peoples concern doesnt matter to the conclusion.We are interested in knowing how it will impact the cost.
(B) Commercials using famous singers are usually more effective than commercials using imitators of famous singers.
Hold on . Peoples concern doesnt matter to the conclusion.We are interested in knowing how it will impact the cost. To some extent it strengthens .Lets try negation..
Commercials using famous singers are
NOT usually more effective than commercials using imitators of famous singers.
My be it is equally active ..may be not...any case after losing lawsuit I cant have imitators ..
Plus We are interested in knowing how it will impact the cost and it doesn't tell anything about it.
(C) The original versions of some well-known songs are unavailable for use in commercials.
Weaken.Opposite choice. In that case ..to some extent it weakens the conclusion..This means we wont be able to have renditions of those famous songs.
(D) Advertising firms will continue to use imitators to mimic the physical mannerisms of famous singers.
Irrelevant . Imitators to mimic the physical mannerisms of famous singers--This doesnt impact the cost or conclusion.
(E) The advertising industry will use well-known renditions of songs in commercial
Perfect!!
Negation gives The advertising industry
will NOT use well-known renditions of songs in commercial
If the famous singers are not used then the cost will not rise and this will hurt the conclusion.
So this is something which must be true for the argument to hold.
