I dont think I got this right. However, its better to try.
The assumption seems to be that the agency fears that dictators will file a case if any impersonators are used, so only dictators will be used for ads. Conclusion is ad costs will raise as dictators charge more. Stated concl is ad cost will increase.
If it has to be flawed, conclusion becomes that ad cost will not increase.So to support the flawed conclusion, the assumption has to be dictators will not be used, so costs will go down, else already only dictators are used for ads so there wont be any diff in ad costs(dont shoot up).
A) Most listeners cannot distinguish whether a speech is being performed by a famous dictator or an impersonator.
here no info if impersonation leads to lawsuit. So we dont know if agency will use dictators or impersonators.
B) Ads which use famous dictators are often more effective than those which use impersonators.
Here they say that not only dictators but also impersonators are used for ads already. So even if the ad is more effective with dictators, if dictators are used it leads to high cost.
C) Some famous speeches’ original versions cannot be licensed for commercial use.
No info about the choice of use, dictators or impersonators.
D) Booking agencies will continue using impersonators in place of famous dictators.
Yes, I feel so.. If agency continue to use impersonators, they are not scared about lawsuit. And the ad cost will be less. So conclution is flawed.
E) Advertisers will want to use original speeches.
Original speeches will be given only by dictators. So the cost of ad will go high.
Please let me know about my approach..
