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 or S_3(a_5). w -> P_7(a_5). forall x_7: P_7(x_7) or ~S_3(x_7).
R_1(a_5) -> w can be inferred via the rewriting rule. forall x_7: S_3(x_7) -> P_7(x_7) can be inferred via the universal rewriting rule.
