Q11

If you know that two tourists go to X, then you know that only one goes to V. This is because each guide must have at least one tourist.

So, you've got to place the three remaining tourists (K, M, N), two in X, and one in V.

Clearly, the conditional constraint is going to be involved:
Kx --> Mf
~Mf --> ~Kx

This means that both K and M cannot go together with X. By inference, this means that N cannot go in V (or speak French).

Ok, with that in mind let's go to the choices.

(A) nope. only options for N are Turkish or Spanish
(B) nope. one of them must speak either Turkish or Spanish.
(C) nope. this would put K and M together in X, which breaks the conditional constraint above.
(D) same as (C).
(E) yes. this could be true.
