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 -> s_4. S_15(a_15) -> p. q_4 -> R_15(a_15). forall x_15: R_15(x_15) -> S_15(x_15). s_4 -> q_4.
t -> q_4 can be inferred via the transitivity rule. s_4 -> R_15(a_15) can be inferred via the transitivity rule.
