Consider the following premises. forall x_17: P_3(x_17) and Q_17(x_17). forall x_11: P_11(x_11). forall x_11: P_11(x_11) -> R(x_11). Can we infer forall x_11: ~(P_3(x_11) and R(x_11)) from them? If possible, name the inference rules being used at each step.
That contradicts the premises. Therefore the answer is no.
