Answer :
Final answer:
The passage marks the end of Buck's life with humans as he senses the death of his human companion and decides to move on.
Explanation:
The story episode that is coming to an end in the passage provided is Buck's life with humans. In the text we see that the dog senses the death of the man and decides to leave, which indicates that Buck's connection with human companionship is coming to a close. Buck is now set to embark on a new episode, presumably one that involves a deeper integration into the wilderness and a reliance on his primal instincts rather than the nurturing forces of society. This transition echoes the central theme of Jack London's The Call of the Wild, where the struggle between the forces of nature and nurture is portrayed through Buck's journey.
