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: ~p. forall x_14: P(x_14) -> S_14(x_14). p or P(d).
P(d) can be inferred via the disjunctive syllogism rule. R_1(d) -> p can be inferred via the rewriting rule.
