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: forall x_10: U_3(x_10) -> S_10(x_10). p_3 <-> S_10(a_10). U_3(a_10) or p_3.
p_3 -> S_10(a_10) can be inferred via the biconditional elimination rule. S_10(a_10) -> p_3 can be inferred via the biconditional elimination rule.
