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: For all x_14, x_14 will play squash or x_14 is not rich. For all x_14, if x_14 cooks, then x_14 is playing squash. There is at least one x_14 for which x_14 is an electrician or x_14 is rich. For all x_14, x_14 is not an electrician or x_14 will cook.
There is at least one x_14 for which x_14 is rich or x_14 will cook can be inferred via the existential resolution rule. For all x_14, if x_14 were rich, then x_14 is playing squash can be inferred via the universal rewriting rule.
