I don't think the question was poorly worded. The question was, in my opinion, written to make you think, what are the possible answers? How many ways can something be done? Using the statement, invoke the application role, how many ways can it be invoked? Based on that, how many ways can you revert back to the original context? This is elementary problem solving.

I will agree, that there have been some questions that have been poorly written and/or actually had no correct answers. This isn't one of them, IMHO.
