What elements of the story are considered realistic?

The choice that highlights the realistic elements of the story focuses on the personalities of the children and the school on an island. This reflects a grounded aspect of the narrative, as the children's experiences, emotions, challenges, and growth are relatable and mirror real-life situations. The realistic portrayal of their personalities allows readers to connect with them on a personal level, making the story resonate.

Additionally, the setting, while unique, also embodies realistic themes, such as the pressures of education and the dynamics of group interactions among children. The complexities of friendships and the struggles against authority reflect real-world scenarios, contributing to the overall authenticity of the narrative, distinguishing it from elements that are more fantastical or out of the ordinary. The other choices involve imaginative concepts that step outside the boundaries of realism, emphasizing adventure, special skills, or fantastical settings that do not mirror typical human experiences or environments.
