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: p_2 -> S_16(a_16). forall x_16: R_16(x_16) <-> S_16(x_16). R_16(a_16) or p_2. q_3 -> ~S_16(a_16).
forall x_16: R_16(x_16) -> S_16(x_16) can be inferred via the universal biconditional elimination rule. forall x_16: S_16(x_16) -> R_16(x_16) can be inferred via the universal biconditional elimination rule.
