Consider the following premises. forall x_12: R_12(x_12) -> Q_5(x_12). forall x_12: P_12(x_12) -> R_12(x_12). forall x_12: P_12(x_12) or Q_12(x_12). forall x_12: Q_12(x_12) -> R_12(x_12). forall x_12: Q_5(x_12) -> R_5(x_12). exists x_12: P_3(x_12) -> ~R_5(x_12). Can we infer forall x_12: R_12(x_12) -> Q_5(x_12) from them?
That is one of the premises. Therefore, the answer is yes.
