45 Game 3
Comments

I think one difficulty of this game is that, to make the diagram and rule notation more compatible, one has to choose the "not alone" group as the "in" group.
Another difficulty for myself is to understand the sentence "or in groups with one another". I thought it meant "in pair", and I stuck in Q13 and Q14.
The game is actually not so hard on retake.

Well, I made the "in" group the students who were in a picture, so the "out" group was the students who were not in a picture.
And oh, yeah. If it were pairs, that would change things a lot!

I'm still not understanding Question 13. How can B be an accurate list of who can appear together when Raimundo and Yakira cannot be in the same picture?

There's no rule keeping Raimundo and Yakira from being together (NOTHING CAN STOP THEIR LOVE). The rule only says they cannot both be out at the same time!
