Question

You just saw a video ad that shows a man talking about the diet pill he uses. He doesn't appear to be reading a script, and the words at the bottom of the screen tell you he is not an actor. What technique has the advertising company used to persuade you to use the diet pill?

Answer 1

Bandwagon
Plain folks
Scientific evidence
Glittering generalities

Answer 2

I would say B.

Plain folks is a form of propaganda and a logical fallacy. A plain folks argument is one in which the speaker presents him or herself as an average Joe — a common person who can understand and empathize with a listener's concerns.
