Yes Shekhar, but if Laura were do set up a couple Variables for each question, she could do what she wanted. One variable tracks whether the question was answered correctly or not. The other variable contains a text-based explanation of the correct answer that can be displayed in a caption that gets shown ON SLIDE ENTER.
The missing piece in the equation, as it has always been missing in Captivate, is to have a system variable that tells you when you are in Review mode. That variable would enable use of Conditional Advanced Actions that only fired during Review Mode.
