First of all,  thanks a lot for downloading my powerpoint. Secondly, regarding the problem you have with viewing the correct answer along with the four possibilities, I have to tell you this doesn�t happen when you display the powerpoint presentation. You�ll find the question, then the four possible answers will appear and finally, the correct answer in green, but only by clicking on the presentation, just as if you wanted to move on to the following slide. I hope this explanation will make it clearer. Sorry for not giving you better instructions from the beginning and thanks one more time.
