...if one of your mid-term questions begins with the sentence "Dr. E is an environmentalist and a critic of economics. On the Charlie Rose Show he attacks an economics text as follows", there is an extremely high probability that your professor is going to expect you to disagree with whatever follows.
You are better off saying you disagree and just throwing random vocabulary from class together than you are defending whatever follows.
You are, of course, best off knowing why the hypothetical character is wrong.
Regardless of whether you go for the better option or the best option - don't expect to get anywhere by saying the guy is right.
