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: exists x_4: T_2(x_4) or P_3(x_4). forall x_4: ~P_3(x_4). forall x_4: ~T_2(x_4) or T(x_4).
exists x_4: P_3(x_4) or T(x_4) can be inferred via the existential resolution rule.
