If we're told to assume the line 3 tickets for January are red, and we've already been told the line 2 tickets for January are purple, that means the line 1 January tickets must be green or yellow. If the line 3 January tickets are Red, then line three Feb must be green as we're told in rule 5. Doesn't that mean that line 1 Jan can't be green, per rule 3?

    Hi @okburns, Thanks for the question! Well, remember, this question is asking what MUST be true. Do the line 1 tickets for January HAVE to be green? No. As we see below: If line 3 tickets for January are red, then line 3 tickets for February have to be green. So we have: Jan: ? P R Feb: ? ? G The remaining color is January is yellow or green. There should be three possibilities: Jan: Y P R?Feb: R Y G or Jan: G P R Feb: R Y G or Jan: G P R Feb: Y R G Hope this helps! Feel free to ask any other questions that you might have.
