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: W(g) <-> w_3. p <-> w_3. forall z: ~W(z).
W(g) -> w_3 can be inferred via the biconditional elimination rule. p -> w_3 can be inferred via the biconditional elimination rule. w_3 -> W(g) can be inferred via the biconditional elimination rule. w_3 -> p can be inferred via the biconditional elimination rule.
