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_3(h) <-> q. p_1. forall z_1: ~Q_3(z_1).
Q_3(h) -> q can be inferred via the biconditional elimination rule. q -> Q_3(h) can be inferred via the biconditional elimination rule.
