Consider the following premises. forall x_16: U_2(x_16) or ~Q_16(x_16). forall x_16: P_11(x_16) or Q_16(x_16). exists x_16: Q_11(x_16) -> U_2(x_16). forall x_16: P_11(x_16) -> Q_11(x_16). Can we infer exists x_16: U_2(x_16) or U_3(x_16) from them?
 From forall x_16: U_2(x_16) or ~Q_16(x_16) we can infer forall x_16: Q_16(x_16) -> U_2(x_16). From forall x_16: P_11(x_16) -> Q_11(x_16), exists x_16: Q_11(x_16) -> U_2(x_16) we can infer exists x_16: P_11(x_16) -> U_2(x_16). From exists x_16: P_11(x_16) -> U_2(x_16), forall x_16: Q_16(x_16) -> U_2(x_16), forall x_16: P_11(x_16) or Q_16(x_16) we can infer exists x_16: U_2(x_16). Finally, from exists x_16: U_2(x_16) we can infer exists x_16: U_2(x_16) or U_3(x_16). Therefore, the answer is yes.
