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: q_4 <-> R_10(a_10). forall x_10: R_10(x_10) -> S_10(x_10).
q_4 -> R_10(a_10) can be inferred via the biconditional elimination rule. R_10(a_10) -> q_4 can be inferred via the biconditional elimination rule.
