Must be false

Hi, general must be false questions often do take a bit more time. I would start be eliminating answer choices we know could be true using prior scenarios and the work we did in earlier questions, and then try to tame out each remaining answer choice. When we try A, we know that 1 must be purple, so we have P G _ _ _ _ We also know that the third one can no longer be green, and it can't be purple since our other people needs to be five or six, so it must be orange. P G O _ _ _ This means that 4 can't be orange, and we know it can't be green from the rules, and that it cannot be purple since we need our last purple for the last two. Thus, this scenario is not possible.
