Final answer:
The question explores the reasons behind characters' actions when faced with life-and-death situations across different literary works. It delves into the complex motivations, from the desire for freedom to the instinctive need to survive, that compel characters to act in extreme circumstances.
Step-by-step explanation:
The central theme of the question pertains to the motivations and internal conflicts that characters experience when facing life-threatening or oppressive situations. These narratives, drawn from various literary contexts, depict individuals in dire circumstances—whether escaping slavery, enduring the extreme cold, facing war, or confronting the imminent risk of death.
The passages highlight a range of human responses, including the will to survive, the acceptance of death as an escape from suffering, and the physiological fight or flight response. The characters are propelled into action by their desire for freedom, the instinct to live, or a deep-seated need to escape unbearable conditions.
These selections illustrate not just physical struggles but also profound psychological battles. The characters grapple with hope, fear, and despair, which drive their decisions to either cling to life or resign themselves to death.
