Final answer:
The texts describe tragic events that occurred on specific nights, but the reasons behind these events are not explicitly explained. They raise questions about human emotions, connections, and the potential for prevention.
Step-by-step explanation:
In the given texts, each describes a tragic event that occurred on a specific night. Although the reasons for the fire and the death of the cats are not explicitly explained in the texts, the dynamics and circumstances surrounding each event can provide some insight.
For example, in the story about the fireman and his dog, the speaker retells the story to emphasize the emotional connection and empathy between the fireman and his companion, which raises questions about our capacity for empathy and forgiveness. In the account of the Library fire, the timing of the incident and the destruction of the Library suggest a tragic consequence of a fire that was out of control. Similarly, the destruction of Persepolis can be speculated upon but not definitively explained.
Overall, the texts present tragic events that highlight the fragility of life and raise questions about human emotions, connections, and the potential for prevention.
