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_2: Q_4(x_2) or ~T(x_2). exists x_2: T(x_2).
forall x_2: T(x_2) -> Q_4(x_2) can be inferred via the universal rewriting rule.
