In this section you will read three sets of questions, followed by five answer choices for each set. Answer all questions following the directions given with each set, using only the information given in the text and any tables provided. You may refer back to previous sections if necessary. A passage-based exam like this one is not timed; there are no penalties for taking more than 45 seconds to read a question or write an answer; and you can go back and rewrite anything you do not understand when answering these questions (in other words, “ cribbing” is allowed). You should not make bold marks on your paper where explanations would be placed—only use black ink for crosses out ( ) when something is wrong! The answers begin below these practice test questions . We recommend that you take plenty of rest before beginning Section II because it can be very difficult without preparation! Good luck!
