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 y: P_3(y) or ~T(y). forall y: P_2(y) or ~P_3(y).
forall y: P_3(y) -> P_2(y) can be inferred via the universal rewriting rule. exists y: T(y) -> P_3(y) can be inferred via the existential rewriting rule.
