The correct answer is B, while the program shows the correct answer is C. Linguistics and Zoology cannot both be covered by Ferreh

Sorry, correct answer is A, not B. Typo**

This is a CANNOT be true question. A and B are both possible options. C is the only option that is not possible.

A) If F has L,P, S then your left with M,R,Z for G and H. H has to have 2 but cant have M so it gets R and Z leaving G with M. This also satisfies the rule that if G has M it cannot have anything else. So this looks like the following and is valid:

F: L P S
G: M
H: R Z

B) This one is very similar to A. If L has L, R, and Z that leaves M, P, S for G and H. H needs 2 and cant have M, also P and S have to go together, so P and S go in H. And this leaves M for G. Again satisfying the rule that if G has M then it cannot have anything else. This looks like the following and is valid:

F: L R Z
G: M
H: P S

C) This one gives you P, S, R in G leaving you with L, Z, M for F and H. We know H needs two but also know one of L and Z must be in F from the first rule and M cannot be in H. This leaves us only the remaining of L and Z for H but it needs two so there is no valid scenario. This answer cannot be true and is the answer

Why does H need two spots? Isn't one spot enough?
H and F can have either L or Z, correct? Meanwhile, F can have M, L or Z.

Nvm, I forgot one of the rules for H. Thanks
