Consider the following premises. 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: P_4(x_12) -> S(x_12). forall x_12: Q_12(x_12) -> R_12(x_12). forall x_12: R_12(x_12) -> P_4(x_12). Can we infer W_4(f) from them?
We cannot infer that from the premises. Therefore the answer is no.
