Recently a renowned model won a lawsuit against an advertising company for using a 'double' in a commercial endorsement of a beauty product. Consequently advertising companies will stop using 'look-alikes' or 'doubles'. This is bound to result in an increase in advertising costs, as famous artists charge a much higher fee than do their 'look-alikes'.

The argument above depends upon which of the following assumptions?

Advertisements using renowned models are usually more effective than those using 'doubles' or less well known faces.

Famous models are sometimes not available, or not willing to do 'shoots' for purely cosmetic products.

The advertising industry will rely on renowned models and known faces in their commercials.

The advertising industry will not use fresher and prettier models for their products.

Viewers are usually unable to immediately distinguish between a well-known model and his/ her double.
