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: S_4(a_10) <-> t_3. ~S_10(a_10). forall x_10: S_4(x_10) -> S_10(x_10).
S_4(a_10) -> t_3 can be inferred via the biconditional elimination rule. t_3 -> S_4(a_10) can be inferred via the biconditional elimination rule.
