Consider the following premises. forall x_17: P_17(x_17) -> Q_10(x_17). forall x_17: W(x_17) or T(x_17). forall x_17: W(x_17) -> P_17(x_17). exists x_17: ~Q_10(x_17). forall x_17: P_17(x_17) -> W(x_17). Can we infer forall x_17: ~T(x_17) from them?
 From forall x_17: P_17(x_17) -> W(x_17), forall x_17: W(x_17) -> P_17(x_17) we can infer forall x_17: P_17(x_17) <-> W(x_17). From forall x_17: P_17(x_17) -> Q_10(x_17), exists x_17: ~Q_10(x_17) we can infer exists x_17: ~P_17(x_17). From forall x_17: P_17(x_17) <-> W(x_17), exists x_17: ~P_17(x_17) we can infer exists x_17: ~W(x_17). Finally, from forall x_17: W(x_17) or T(x_17), exists x_17: ~W(x_17) we can infer exists x_17: T(x_17), which contradicts forall x_17: ~T(x_17). Therefore, the answer is no.
