I answered it and second all that
@Mwoods18 responded!
My response was also fairly broad; I wrote about how I was leaning towards the surgical subspecialties and related this interest into some of my projects/hobbies. So yeah, don't feel pressured to wax poetic about your love for primary care if you're actually a die-hard specialist... and vice versa.
As always, just answer honestly. Don't try and pander to what you
think the adcom wants to hear, because I honestly couldn't tell you what they're looking for aside from authenticity and enthusiasm.
