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_2: P(x_2) -> T_3(x_2). forall x_2: T_3(x_2) -> R(x_2). forall x_2: P(x_2) or ~R(x_2).
exists x_2: P(x_2) -> R(x_2) can be inferred via the existential transitivity rule. forall x_2: R(x_2) -> P(x_2) can be inferred via the universal rewriting rule.
