Consider the following premises. forall x_14: P_9(x_14). forall x_14: Q_2(x_14) -> ~Q_9(x_14). forall x_14: ~P_9(x_14). forall x_14: Q_2(x_14) <-> T_4(x_14). Can we infer exists x_14: T_4(x_14) from them? If possible, name the inference rules being used at each step.
The premises are contradictory and we can infer anything from them. Therefore, the answer is yes.
