Consider the following premises. forall x_5: Q_5(x_5). forall x_5: T(x_5) -> ~Q_5(x_5). exists x_5: T(x_5). Can we infer forall x_5: ~W_4(x_5) 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.
