Final answer:
In chapter 8 of 'Persepolis', Marji exemplifies restraint by being consciously calm and composed, similar to Bernice's demeanor in the provided text.
Step-by-step explanation:
The concept of someone 'exercising restraint' involves showing self-control and often involves maintaining a calm and unemotional demeanor. In chapter 8 of Persepolis, Marji demonstrates restraint in several ways, reflecting the disciplinary aspects associated with controlling one's emotions and reactions. One example can be seen when Marji appears consciously calm and refrains from displaying excessive emotion, similar to how Bernice reappears 'very red-eyed, and consciously calm' in the provided text. Marji likely navigates through her challenging circumstances by keeping her inner turmoil private and presenting a composed exterior, despite internal conflicts or external chaos, which is a critical element of restraint.
