Hi @bb64,

Thanks for the question! So we’re trying to get V as the project leader. Well, what happens if V is a project leader? W isn’t on the project because of the contrapositive of rule 3. We also know that Q and R can’t be in either, because if they’re in, they’re project leaders according to rule 1. So that leaves us with V, and 2/3 of S, T, and X. And if we pick S, we have to pick T according to rule 2. So we either get to have V, S, and T; or V, T, and X.

So now taking a look at (A), it says that we don’t pick Q or S. Well, we already know we don’t pick Q. And if we pick T and X, we avoid picking S. So (A) is the correct answer.

Hope this helps! Feel free to ask any other questions that you might have.
