Consider the following premises. exists x_9: T_2(x_9) or W(x_9). forall x_9: W(x_9) -> S(x_9). forall x_9: T_2(x_9) -> S(x_9). forall x_9: P_3(x_9). Can we infer forall x_9: ~(S(x_9) and P_3(x_9)) from them?
 From forall x_9: T_2(x_9) -> S(x_9), forall x_9: W(x_9) -> S(x_9), exists x_9: T_2(x_9) or W(x_9) we can infer exists x_9: S(x_9). Finally, from exists x_9: S(x_9), forall x_9: P_3(x_9) we can infer exists x_9: S(x_9) and P_3(x_9), which contradicts forall x_9: ~(S(x_9) and P_3(x_9)). Therefore, the answer is no.
