@Arkavian Were you ever able to understand this issue? I'm currently stuck on it

@RyanAlexander Where is this information? I looked back at the group 1 and 2 explanation video and "only" is under group 2 . I haven't seen anything about "the only"

I really don't understand #3. Where "only" is supposed to be a necessary condition indicator....the explanation says it is a sufficient condition. I've been trying to understand this for an hour now.
