HF deliberately leave out answers to some "sharpen your pencil" sections, on the grounds that we should check back ourselves. But for the record, I don't agree with this, as you could convince yourself of a wrong answer, and thus not know it was wrong all the way to the exam. And assuming many readers are studying for the exam, there's no incentive to "cheat".
Any comments from Kathy or Bert?
