Okay, can somebody please explain how B is correct. I understand why it is on some level, and why the others are wrong, partially because what all of the wrong answers have in common is basically that the new calendar doesn’t mess with their schedule, but it still isn’t fully clicking to me why B is 100% objectively correct. After reading through the stimulus many times, I still don’t understand the implications of the days before January 1st mixing up so that the group in AC B will eventually run into problems. I’m just really confused. Thanks a lot in advance.
