Manager: Although our corporation lists rules in an orientation booklet, few employees read the booklet carefully enough to familiarize themselves with all the rules. Lecturing employees for inadvertent rule violations often makes them resentful and less cooperative. Thus, to improve employee adherence to rules, we plan to issue gentle reminders about various rules in each issue of our weekly newsletter. Which of the following would it be most helpful to discover about the employees in the corporation in order to evaluate the likelihood that the plan will succeed? ['Whether most of them violate at least some rules with which they are familiar', 'Whether most of them who inadvertently violate rules already feel resentful and uncooperative', 'Whether most of them would usually read with sufficient care the portions of the weekly newsletter that are reminders of rules', 'Whether most of them who regularly read the weekly newsletter are familiar with at least some rules']
