Mach Scale And Ethical Behavior

Grant is taking an exam when his teacher leaves the room for an emergency, instructing the class to continue working silently. Another student discovers the answer key on the teacher's desk and passes it around the classroom. Grant refuses to look at the answer key when it reaches his desk and continues to complete his test independently. Based on this behavior, where does Grant most likely fall on the Machiavellian (Mach) scale?
