Take a look at the sentence again:
While sitting in English class, Peterson wonders how Dr. Jones can speak
so passionately about comma splices, why she would spend her free evenings
voluntarily reading Shakespeare, and __________.
The blank requires a subordinate clause. You chose does she ever have some real fun, which is a main clause and thus causes a parallelism error. Before you continue, review the rules for parallel structure.
