Boo to all of you!

There was an error on the practice problems. The very first one, regarding the basic concern of economics. The answer key said D. But didn't that seem a bit backward? Because it was. The best answer was C: studying the choices people make.

NO ONE contacted me and asked me about that. You should have. So "boo to you".

Moreover, I went ahead and included that same problem on the test, but of course, using care, I put the correct answer, C, on the test.

So I'm going to throw out the question.
