Okay, here's the key. Highlight number 4 and the paragraph immediately below it. Also be sure to point out that you are supposed to slow down BEFORE the turn. Be nice when you're talking to them, DON'T be an A$$, regardless of what they say or do. If the first person you talk to refuses to change the answer and pass you, then kindly ask to speak to their supervisor. If they refuse, then kindly ask to speak to THEIR supervisor. Continue doing that until there is nobody higher up. If the highest person refuses to pass you, then I guess you have to wait until Friday. Just be sure to have the book with you and be able to point out the right answer, which you have in front of you. And remember, BE NICE and STAY CALM, regardless of what they say or do. You will get farther that way.
