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: ~Q_2(g). forall x: W_2(x) -> Q_2(x). forall x: Q_2(x) -> W_2(x).
forall x: W_2(x) <-> Q_2(x) can be inferred via the universal biconditional introduction rule. forall x: Q_2(x) <-> W_2(x) can be inferred via the universal biconditional introduction rule.
