2. Copyright 2005 Ted "Smitty" Smith Directions Left click on the presentation ICON located at the bottom of the slide directory to the left of the this slide. Each slide will transition to the correct answer automatically in 2:00 minutes. The correct answer will transition in 5 seconds. Do not worry about writing down the correct answer for now. You will have the opportunity to do that at the end of the two minute drill Good luck

3. Further More You have seen all of these questions before. This time the slides will transition at different rates of speed. Remember do not worry about writing down the right answer for now. When you reach the end all of the slides will be repeated without the timer so you can take your time to find the ones you missed and write down the correct answers then.
