Answer:
In the chapter, there are several details both implicit and explicit that help make inferences about the young Helen Keller.
One explicit detail is that Helen was deaf and blind from a young age. Her inability to hear or see affected her ability to communicate with those around her, creating frustration and isolation. This detail implies that Helen may have struggled with feelings of loneliness and difficulty expressing her thoughts and emotions.
Another implicit detail is that Helen had a strong-willed personality. This can be inferred from her early interactions with her family, particularly her father, who describes her as "a wild child." Despite her limitations, Helen is shown to be a determined and persistent individual, as evidenced by her efforts to communicate through touch and eventually learn language with the help of her teacher, Annie Sullivan.
Overall, these details provide insight into the challenges and strengths of the young Helen Keller, helping readers to understand her experience and character.
