Which one of the following could be an accurate list, for each of the nations, of the crops it exports?

Need further explanation about the Set up in the last game
Hello,
I have a question about the two scenarios we came up with in this game. In the first scenario, she put soybeans with Nation X and Y, which invoked the contrapositive of Rule 3, allowing her to make a deduction that Nation Y cannot have Rice. I am confused why she only eliminated Rice as an option when the contrapositive is:
Not X(t) or NOT Z(t) --> Not Y(r)
How come she did not eliminate T from Nation's X and Z? Why did she only eliminate R from Nation Y?
Thank you!

Because that isn't how conditional reasoning works. If s is in two, that means no other crop can appear twice, so therefore t cant be in both X and z. If t is not in both, then y can't have r. Nothing about this guarantees that t cannot be in either of the, it could totally be in one but not the other. It just can't be in both.
