My personal preference for the highlight is the *not* (coming from an old e-mail / Usenet convention indicating bold font), but I do NOT

It's become the way quiz players expect it to be marked when it is used to indicate a "3 true and 1 false statement" answer set and anything else would just cause people to perform worse, so I made it a habit to both write and edit with this formatting. Ultimately, consistency and play efficiency are the most important aspects of question and answer formatting.
