Consider the following premises. forall x_15: U(x_15) or ~T(x_15). forall x_15: ~P_8(x_15). forall x_15: R_1(x_15) -> U(x_15). exists x_15: P_8(x_15) or W(x_15). forall x_15: R_1(x_15) or T(x_15). Can we infer exists x_15: U(x_15) and W(x_15) from them?
 From forall x_15: U(x_15) or ~T(x_15) we can infer forall x_15: T(x_15) -> U(x_15). From exists x_15: P_8(x_15) or W(x_15), forall x_15: ~P_8(x_15) we can infer exists x_15: W(x_15). From forall x_15: R_1(x_15) -> U(x_15), forall x_15: T(x_15) -> U(x_15), forall x_15: R_1(x_15) or T(x_15) we can infer forall x_15: U(x_15). Finally, from forall x_15: U(x_15), exists x_15: W(x_15) we can infer exists x_15: U(x_15) and W(x_15). Therefore, the answer is yes.
