What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? Name the inference rule being used: forall x_6: T_1(x_6) -> ~S_4(x_6). forall x_6: Q_1(x_6) -> Q(x_6). forall x_6: S_4(x_6). forall x_6: Q_1(x_6).
forall x_6: Q(x_6) can be inferred via the universal modus ponens rule. forall x_6: ~T_1(x_6) can be inferred via the universal modus tollens rule. forall x_6: S_4(x_6) and Q_1(x_6) can be inferred via the universal conjunction rule. forall x_6: Q_1(x_6) and S_4(x_6) can be inferred via the universal conjunction rule.
