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_3 -> ~S_17(a_17). w_3 <-> p. ~R_17(a_17). forall x_17: R_17(x_17) or S_17(x_17).
w_3 -> p can be inferred via the biconditional elimination rule. p -> w_3 can be inferred via the biconditional elimination rule.
