Hide after choosing

Question

Hello! I'm trying to create a reading quiz for my students, and upload it on Moodle. The quiz is about a short reading. Students have five questions and three possible answers. Once a student chooses an answer I want all the other answers to  hide, until the finish all the five questions. The problem is this: every time I click on an answer, the slideshow continues being played until the last slide, and there's no time to answer all the other questions. I've grouped every question's buttons. There's a total of five groups, and on the action menu, I've chosen to hide the group that button belongs to. I've already assigned the correct answers and their score, as well. Anyways... I've just recently read from a Cp trainer, "...another user trying to run the marathon without training..." anyways, I just want to figure out how to solve this issue.
P.S: here you have a picture on the look and the quiz layout

Lochrecan,
The interaction that you show above is actually not a trivial thing to set up.  It would require several user variables (one variable for each question group to record the user's selected answer).  And there are a number of possible ways you could set up the Advanced Actions, depending on the specifics of how you wanted the interaction to work. 
One way would be to have a separate Standard Advanced Action for each and every button that assigned the value of the relevant variable for that button group and then hid all the buttons in that group.  (As Lieve pointed out, you don't need to add a Pause action to Standard or Conditional Advanced Actions because they're paused by default.)  Each of these Standard Advanced Actions will be executed by clicking buttons in the question groups.  You set the button's On Success actions to execute their relevant Standard Action.
However, you will also need another Conditional Advanced Action that will be used to evaluate the user's selected answers, decide whether or not they have answered correctly, and then progress the user to a different slide.  This Conditional Action would be executed by the button at the bottom of the slide.  It will be quite a complex Conditional Action with several Decision Blocks.  It will first need to make sure that the user has indeed entered an answer for each and every question, before then evaluating each of these answers to compare against the correct answers.
All of this is just a quick overview of what would be required to create this interaction.
Since it's obvious you're not as yet very proficient with Advanced Actions and Variables, I think you may have bitten off more than you can chew at this point in your career with Captivate.  So getting this all sorted by Monday might not be possible...realistically.
My recommendation is that you need to learn a lot more about the concepts, terminology and technicalities of Captivate's Advanced Actions framework first.
Take a look at this e-book if you want something in-depth to study.  But be warned...it's likely to take you more than a weekend to get your head around all of this.
