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(a) or ~q_12. forall x_4: T(x_4) <-> Q(x_4). q_12.
q_12 -> Q(a) can be inferred via the rewriting rule. forall x_4: T(x_4) -> Q(x_4) can be inferred via the universal biconditional elimination rule. forall x_4: Q(x_4) -> T(x_4) can be inferred via the universal biconditional elimination rule.
