Drug manufacturer: Television audiences are sure to realize that the physician recommending our brand of cough syrup in our advertisement is actually an actor playing a role. Hence they will not place undue trust in the advice given by this actor. Ttherefore, networks should relax their guidelines to permit our company to broadcast this advertisement. Television executive: If the audience can tell that the actor is not a physician, then your advertisement need not have a physician figure recommending your product.
The argumentative strategy used by the television executive in response to the drug manufacturer is indicating that the reason the drug manufacturer offers for relaxing the guidelines conflicts with the manufacturer's presumed motive for presenting the image of a physician in the advertisement.
