Mandolin, sorry to say it, but i think you were rather foolish to PAY for the answers and questions when there are sereval internet sites that have full practice quizes.
I practiced for mine at
http://www.cristcdl.com/otc/ at passed first time. And yes, the question you presented to us was on the test I took. Its my understanding that the federal gov't makes up thoses tests. Not each state. Therefore, they are all the same. Make sure you study ALL pages of the general knowledge test, along with ALL pages of airbrakes, combination, and pre-trip. You will have a MASSIVE headache (I did), but you WILL pass the permit test, and thats all that matters. I remember that on that website in the general knowledge part, it looks like its turning into a School bus test, but keep on doing all the questions. If you dont you'll be sorry. Study them till you know them all 100%!!!!!!!!!!!!! Dont miss any! Like I said, most important, do ALL pages of general knowledge.
Hope I helped.
Good luck.
