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
Copyright 2005 Ted "Smitty" Smith
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.
