I cannot believe I cannot find the answer by googling;8-)
The issue: I have LaTeX article I process with PdfLaTeX. The text is a question with multiple-choice options. Currently, the correct answer is given on the same page, under the question and multiple-choice options. I would like to have a version of the LaTeX file where the text is "paused" after the question and itemized list of possible answers and the user needs to hit return to reveal the answer. Obviously, I don't want to go through the trouble of duplicating every page, with one having a question with multiple options and the next one having a question + multiple options + correct answer.
I was thinking I could find a simple solution, like inserting just one command before the answer, something like
beamer. But I could not find the solution!
