Final answer:
Levi's methods for avoiding self-destruction while retaining humanity likely include organization and pity but not theft or betrayal. The last two are fundamentally at odds with likely maintaining humanity's integrity in crisis times, making 'd. betrayal' the correct answer to the student's question.
Step-by-step explanation:
The question refers to the three methods humanity can use to prevent self-destruction while still maintaining its humanity, as believed by the character Levi in a literary work. These methods are likely tied to ways society can organize itself to avoid the state of chaos and war described by Thomas Hobbes in his social contract theory.
Levi's methods are typically organization, pity, and another method not specified. It is important to recognize that the concepts of theft and betrayal typically do not align with upholding the integrity of humanity in the face of adversity. In contrast, organization and pity are aspects that can contribute to social cohesion and the avoidance of the brutish state of nature that Hobbes describes.
Therefore, the answer to the student's question would be 'd. betrayal' as it does not fit with the other methods which are more constructive to maintaining our humanity during crises.
