Consider the following premises. forall x_7: ~P_6(x_7) or T(x_7). forall x_7: U(x_7) -> Q_7(x_7). forall x_7: P_6(x_7) or U(x_7). forall x_7: ~Q_7(x_7). Can we infer ~T(c_4) from them?
 From forall x_7: U(x_7) -> Q_7(x_7), forall x_7: ~Q_7(x_7) we can infer forall x_7: ~U(x_7). From forall x_7: P_6(x_7) or U(x_7), forall x_7: ~P_6(x_7) or T(x_7) we can infer forall x_7: U(x_7) or T(x_7). Finally, from forall x_7: U(x_7) or T(x_7), forall x_7: ~U(x_7) we can infer forall x_7: T(x_7), which contradicts ~T(c_4). Therefore, the answer is no.
