Lol so I actually screwed that question up, I think the exact wording was posted earlier in this thread: "Please briefly explain any lapses in your undergraduate education; include any in enrollment during your undergraduate education and/or any gaps between undergraduate education and applying to medical school. (example: poor grades, multiple withdraws, health reasons, etc.)". I have several gap years after undergrad but misread the question and left it blank because I thought it was only asking about lapses during undergrad. I emailed the Dean of Admissions after I realized this because I was worried but she said it should be fine because my gap year activities were described in my AMCAS app. But to answer your question, it does seem to be asking about gap years so I would mention why you decided to take gap years.
