I am trying to create a lesson where learners will be asked to identify correctly several different elements within a graph. I would like to use audio to prompt the learner (i.e. Identify the axis that shows hours per day) with the question then upon selection there will be a response (Yes, that is the axis. You can see here... No, that is incorrect because...). If I am using the same graph can I make this one slide with multiple layers or should I use multiple slides?
