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 z, z is a police officer or z is not curious. There is at least one z for which z is curious or z is not a police officer.
For all z, if z were curious, then z is a police officer can be inferred via the universal rewriting rule. There is at least one z for which if z were a police officer, then z is curious can be inferred via the existential rewriting rule.
