Answer: C. "How do you like this great new TV show?"
The term "great" put in there skews the question to make people think the show is great, when it may not be. So people may have a tendency to say they really like the show when they may not.
Or perhaps they may like the show (somewhat) but the fact that they can sense the bias built into the question makes them decide to say opposite and say they don't like the show. Maybe this sort of scenario would have them rebel in a way.
Either way, the use of "great" is likely to alter the opinion of people answering the question.
