Final answer:
The scenario where Katie resists the temptation to shoplift by reminding herself of her principles illustrates the concept of self-control, the capacity to regulate one's conduct in the face of temptations.
Step-by-step explanation:
Though Katie is frequently tempted to shoplift, she is able to resist this temptation by telling herself that shoplifting is wrong and that it is against her principles. This scenario best illustrates the concept of self-control. Self-control is the ability to regulate one's emotions, thoughts, and behavior in the face of temptation and impulses. As an example, resisting the urge to shoplift, despite the temptation, demonstrates one's ability to maintain self-control and adhere to personal and societal norms.
