Consider the following premises. forall x_3: ~Q_3(x_3). exists x_3: T_4(x_3) -> Q_3(x_3). forall x_3: T_4(x_3). Can we infer forall x_3: ~Q_1(x_3) 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.
