Step-by-step explanation:
In Chapter 4 of Jack London's Call of the Wild, Buck's actions significantly influence the unfolding events and provide deeper insights into his evolving character. One pivotal action that showcases Buck's intelligence and leadership is his usurpation of the team's leadership.
This decisive action demonstrates Buck's excellent judgment and strategic thinking as he tactically challenges Spitz, establishes order, and successfully leads the sled team. Such behavior exemplifies his adaptability and survival instincts in response to harsh and competitive environments.
Furthermore, as Buck begins to act on his primal instincts, London portrays the struggle between domestication and the natural call of the wild within Buck's character. This transformation reveals the theme of the inherent conflict between the nurturing forces of society and the brutal reality of nature's law.
