Final answer:
The best detail supporting the theme of 'The Wild Dog of Caucomgomoc' relates to the theme found in 'The Call of the Wild,' highlighting the struggle between primitive instincts and social forces, with Buck embodying the struggle for survival in the wilderness. This aligns with the unnamed man's survival alongside his wolf-dog, demonstrating themes of alienation, community, and interdependence.
Step-by-step explanation:
The detail that best supports the theme of 'The Wild Dog of Caucomgomoc' can be drawn from the tension between the innate animal nature and the forces of society as depicted in Jack London's 'The Call of the Wild.' This theme is clearly illustrated when Buck, the protagonist, has to revert to his primitive survival instincts to endure in the Canadian wilderness. Similarly, the unnamed character's struggle alongside his wolf-dog companion in the harsh Yukon environment showcases the overarching theme of humanity's confrontation with the natural world, contrasting the instinctual survival of the dog with the man's reliance on society's nurturing.
Alienation and community are also explored in the story as recurring themes reflecting the individual's relationship with the larger society and wilderness. The man's reliance on his dog for survival emphasizes the theme of interdependence between humans and nature, as well as between individuals within or apart from society.
