Where does it say that in the rules? The third rule in the workbook states "Saffron is not included in the same recipe as turmeric.".

Hey Kferry,

So because this is a binary game, when the third rule states, S and T cannot be included in the same dish, we get that at least one of them has to be in the appetizer and one of them has to be in the main. So we cannot have a complete list of main dishes with neither of them present, because that would be forcing both of them into the appetizer category.

In your main diagram, you should have placeholders S/T and F/N both present in both the appetizer and the maindish category. There are quite a lot of tricks in these binary two-group games, but the not-block trick is probably the most important.

I hope this makes sense, and I wish you all of the luck in your studies.

Best,
Ryan
