Consider the following premises. forall x_12: P_5(x_12) or Q(x_12). forall x_12: W_4(x_12) and Q_12(x_12). exists x_12: ~P_5(x_12). Can we infer forall x_12: ~(Q(x_12) and W_4(x_12)) from them? If possible, name the inference rules being used at each step.
That contradicts the premises. Therefore the answer is no.
