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: t_2 -> P(h). s -> t_2. forall y_3: ~P(y_3). P(h) -> s.
s -> P(h) can be inferred via the transitivity rule. P(h) -> t_2 can be inferred via the transitivity rule.
