Final answer:
Helen Keller, though deaf and blind, learned to communicate using finger spelling and later achieved literacy, allowing her to graduate from college and become an activist and lecturer. Her success is a testament to overcoming obstacles with the right support and learning methods.
Step-by-step explanation:
Even though Helen Keller was both deaf and blind, she learned to communicate through various methods including finger spelling and eventually speaking. Her tutor, Anne Sullivan, played a pivotal role in this achievement. Unlike the case mentioned of Danielle, who had severe deficits in communication, Helen Keller was taught that everything has a name and managed to connect finger-spelled words to their corresponding objects. This breakthrough in Keller's understanding was a monumental step that allowed her to achieve literacy in both reading and writing. Keller's literacy journey, coupled with her determination, led her to not only overcome her disabilities but also to graduate from college and become a renowned activist and lecturer. Inspiring figures in history like Helen Keller and contemporary individuals such as Evelyn Glennie demonstrate that with adaptive techniques and support, the challenges posed by disabilities can be surmounted. Their stories underscore the importance of perseverance, innovative learning methods, and the instrumental role of educators in facilitating the learning process for individuals with disabilities.
