As you point out, by wrapping the partial in this "Exercise" section, we end up with an extra section that we don't need (we have this outer "Exercise" section as well as the inner "The Question" section).

I recommend modifying the `_question.html.erb` partial to accept an option that says whether or not it is collapsible and if so whether or not it is collapsed.  Then you can remove this outer "Exercise" section leaving you with a partial render call like:

    <%= render "question", student_exercise: @student_exercise, collapsible: true, collapsed: true %>

Make sure that the default values for `collapsible` and `collapsed` are false.  Would be fine to assume that `collapsible` is true if the developer just says `collapsed: true`.
