How does Nick manage to pull himself back up after falling from the tree?

The correct answer highlights the character's physical capability, emphasizing that Nick's strength in his left arm plays a crucial role in his ability to pull himself back up after falling from the tree. This indicates that he possesses enough physical strength to overcome the challenge he faces, showcasing his resilience and determination. The focus on his left arm's strength suggests that it might be a significant trait of his character, perhaps illustrating a broader theme of perseverance or capability in the face of obstacles.

While the other options present various methods of getting back up, they do not align with the way Nick specifically uses his own strength, which is central to the narrative. This aspect of self-reliance serves to underline the theme of personal strength and resourcefulness throughout the context of the story.
