What do you think this "work" means? "to move" or "influence"? I have never seen this kind of usage and this might be an example created by a Korean test-maker.

I have never heard of this expression, so you mean some politician or celebrity make physical contact with the audience on the spot to gain support? Is that action called "work a crowd"? Not any concept of "influencing the audience"?
A comedian can work his audience. It just means that he tailors his material to the people in front of him and manages to get them to appreciate him even more than they might have anyway.
