Read this excerpt from The Story of My Life by Helen Keller. Based on the excerpt, what are Keller’s feelings about the learning differences between children who hear and children who are deaf?

I had now the key to all language, and I was eager to learn to use it. Children who hear acquire language without any particular effort; the words that fall from others' lips they catch on the wing, as it were, delightedly, while the little deaf child must trap them by a slow and often painful process. But whatever the process, the result is wonderful. Gradually from naming an object we advance step by step until we have traversed the vast distance between our first stammered syllable and the sweep of thought in a line of Shakespeare.

A.
Children who hear learn to communicate naturally, while deaf children must overcome obstacles.
B.
Children who are deaf understand difficult language such as Shakespeare with ease.
C.
Children who hear undergo a slow and painful process to learn, while deaf children do not.
D.
Children who are deaf undergo the same gradual process to learn as children who hear.
