Hi Julie - the flower pictures have an initial state of Hidden when the learner arrives at the slide. (The pictures look black-and-white when you open the file in Storyline because objects whose initial states are Hidden are shown as grayed-out in the authoring environment.) So the idea is, the yellow square underneath each picture would contain some text or an image that the learner would match a label to. If they get the match correct, then the picture changes from Hidden to Normal (visible). It might help to check out the following post, where Christina shares how she adapted this template with her own content: community.articulate.com/.../117146.aspx (Be patient though - her sample is hosted on Dropbox so it might feel a little sluggish)
