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: w -> R_15(j_1). forall x_15: R_15(x_15) -> S_15(x_15). S_15(j_1) -> s. s -> r.
S_15(j_1) -> r can be inferred via the transitivity rule.
