Consider the following premises. forall x_16: U_4(x_16) or ~Q_16(x_16). forall x_16: P_11(x_16) or Q_16(x_16). forall x_16: P_11(x_16) -> Q_11(x_16). exists x_16: Q_11(x_16) -> U_4(x_16). Can we infer forall x_16: P_11(x_16) -> Q_11(x_16) from them?
That is one of the premises. Therefore, the answer is yes.
