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: S_15(h_2) <-> w_2. p -> W_1(h_2). forall x_15: W_1(x_15) -> S_15(x_15). p or w_2.
S_15(h_2) -> w_2 can be inferred via the biconditional elimination rule. w_2 -> S_15(h_2) can be inferred via the biconditional elimination rule.
