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: There is at least one x_14 for which x_14 is a server. For all x_14, if x_14 drinks water, then x_14 is not playing squash. For all x_14, x_14 will play squash and x_14 is a police officer.
For all x_14, x_14 will play squash can be inferred via the universal simplification rule. For all x_14, x_14 is a police officer can be inferred via the universal simplification rule.
