I'm not sure (even after reading this subsection) if Choice is the right tool for the job or what, but I'm going to try anyway.

I want to have "optional" sections and activities that are not visible, unless the student has made a specific choice within a certain Choice activity.

The purpose is not to clutter the page with endless "reviews" for those that already know it. But also to add "optional" content for those who chose to see it (with another Choice-activity.

The restrictions on those sectionis/other activity's can only check whether a choice was made or not, but not what choice was made.

Is this possible?
