The text that shows Helen Keller’s strength includes phrases such as "the desire to express myself grew," "my failures to make myself understood were invariably followed by outbursts of passion," "I felt as if invisible hands were holding me," "I made frantic efforts to free myself," and "the spirit of resistance was strong within me." These expressions reflect her determination, inner strength, and resilience in the face of adversity.
Based on this passage, a prepared speaker could share the viewpoint:
"I think Helen Keller’s early outbursts were signals that she was a strong individual."
This perspective recognizes her struggles as a manifestation of her strength and desire for self-expression, rather than merely a result of frustration. It highlights her resilience and the powerful drive to communicate despite the challenges she faced.
