Sarah: Our regulations for staff review are vague and thus difficult to interpret. For instance, the regulations state that a staff member who is performing unsatisfactorily will face dismissal, but they fail to define unsatisfactory performance. Thus, some staff may be dismissed merely because their personal views conflict with those of their supervisors. Which one of the following generalizations, if applicable to Sarah's company, most helps to justify her reasoning? ['A vague regulation can be used to keep those subject to it in subordinate positions.', 'Interpreting regulations is a prerogative that belongs solely to supervisors.', 'Performance that falls only somewhat below expectations results in disciplinary measures short of dismissal.', 'A vague regulation can be used to make those subject to it answer for their performance.']
