Consider the following premises. exists x_14: P_11(x_14) or S(x_14). forall x_14: Q_14(x_14). forall x_14: ~P_11(x_14) or Q_3(x_14). forall x_14: S(x_14) -> ~Q_14(x_14). Can we infer forall x_14: ~(Q_3(x_14) or P(x_14)) from them? If possible, name the inference rules being used at each step.
That contradicts the premises. Therefore the answer is no.
