Consider the following premises. exists x_3: T(x_3) -> R_4(x_3). forall x_3: Q_3(x_3) -> R_4(x_3). forall x_3: W(x_3) -> Q_3(x_3). forall x_3: P_2(x_3) or T(x_3). forall x_3: ~P_2(x_3) or W(x_3). Can we infer forall x_3: W(x_3) -> Q_3(x_3) from them?
That is one of the premises. Therefore, the answer is yes.
