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_10(a_10) <-> q_3. forall x_10: ~R_10(x_10). s <-> q_3.
R_10(a_10) -> q_3 can be inferred via the biconditional elimination rule. s -> q_3 can be inferred via the biconditional elimination rule. q_3 -> R_10(a_10) can be inferred via the biconditional elimination rule. q_3 -> s can be inferred via the biconditional elimination rule.
