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: exists x_10: T(x_10) -> Q(x_10). forall x_10: Q(x_10) <-> P_6(x_10). forall x_10: P_10(x_10) or Q_10(x_10). forall x_10: ~P_10(x_10). forall x_10: P_6(x_10) -> ~Q_10(x_10).
forall x_10: Q_10(x_10) can be inferred via the universal disjunctive syllogism rule. forall x_10: Q(x_10) -> P_6(x_10) can be inferred via the universal biconditional elimination rule. forall x_10: P_6(x_10) -> Q(x_10) can be inferred via the universal biconditional elimination rule.
