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: T_3(x) or Q(x). forall x: T_3(x) <-> S_3(x). exists x: S_2(x). forall x: ~S_3(x).
forall x: T_3(x) -> S_3(x) can be inferred via the universal biconditional elimination rule. forall x: S_3(x) -> T_3(x) can be inferred via the universal biconditional elimination rule. forall x: ~T_3(x) can be inferred via the universal biconditional elimination rule.
