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_7: T_2(x_7) -> P(x_7). forall x_7: T_1(x_7). forall x_7: T_2(x_7) or S(x_7). forall x_7: S(x_7) -> P(x_7).
exists x_7: P(x_7) can be inferred via the existential disjunction elimination rule.
