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: R(c) -> p. forall z_2: R(z_2) <-> W_1(z_2).
forall z_2: R(z_2) -> W_1(z_2) can be inferred via the universal biconditional elimination rule. forall z_2: W_1(z_2) -> R(z_2) can be inferred via the universal biconditional elimination rule.
