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_16(a_16) or u. p_10 <-> u. p_10 or ~S_16(a_16). forall x_16: R_16(x_16) or S_16(x_16).
S_16(a_16) -> p_10 can be inferred via the rewriting rule. p_10 -> u can be inferred via the biconditional elimination rule. u -> p_10 can be inferred via the biconditional elimination rule.
