Suppose Helen Keller was an American author, educator, and advocate for people with disabilities. She was the first deaf-blind person to earn a Bachelor of Arts degree. Keller wrote several books, including 'The Story of My Life', which details her experiences as a deaf-blind person learning to communicate with the help of her teacher Anne Sullivan.
Can we infer that 'Helen Keller never learned to communicate'? Yes, no, or maybe?
