Consider the following premises. ~R_14(a_14). U_3(d) -> S_14(a_14). forall y_2: U_3(y_2) <-> W(y_2). forall x_14: R_14(x_14) <-> S_14(x_14). Can we infer ~W(d) from them?
 From forall x_14: R_14(x_14) <-> S_14(x_14) we can infer R_14(a_14) <-> S_14(a_14). From R_14(a_14) <-> S_14(a_14), ~R_14(a_14) we can infer ~S_14(a_14). From forall y_2: U_3(y_2) <-> W(y_2) we can infer U_3(d) <-> W(d). From U_3(d) -> S_14(a_14), ~S_14(a_14) we can infer ~U_3(d). Finally, from U_3(d) <-> W(d), ~U_3(d) we can infer ~W(d). Therefore, the answer is yes.
