Consider the following premises. forall x_9: R(x_9). forall x_9: Q_5(x_9) -> T(x_9). forall x_9: R(x_9) -> T(x_9). forall x_9: W_3(x_9) -> Q_5(x_9). Can we infer forall x_9: W_3(x_9) -> Q_5(x_9) from them? If possible, name the inference rules being used at each step.
That is one of the premises. Therefore, the answer is yes.
