Question Bank Random Draws

I have created a pre-test question bank with 5 questions. I have inserted a slide into my pre-test scene. I set it to randomly pick a question from the 5 available questions. If I create 5 slides in the scene, will Storyline know which questions it has already presented to the user and only present each question once? If not, how would I accomplish this? Basically, I want two people sitting next to each other to get all 5 questions, but in random order.

Thanks much for the assistance!!
