Read the excerpt from story of my life by helen keller. the morning after my teacher came she led me into her room and gave me a doll. the little blind children at the perkins institution had sent it and laura bridgman had dressed it; but i did not know this until afterward. when i had played with it a little while, miss sullivan slowly spelled into my hand the word "d-o-l-l." i was at once interested in this finger play and tried to imitate it. when i finally succeeded in making the letters correctly i was flushed with childish pleasure and pride. running downstairs to my mother i held up my hand and made the letters for doll. i did not know that i was spelling a word or even that words existed; i was simply making my fingers go in monkey-like imitation. in the days that followed i learned to spell in this uncomprehending way a great many words, among them pin, hat, cup and a few verbs like sit, stand and walk. but my teacher had been with me several weeks before i understood that everything has a name. which detail from the excerpt is a minor detail that is not necessary in a summary? a. laura bridgman had dressed the doll that miss sullivan gave to helen b. after helen played with her doll, miss sullivan spelled the word “d-o-l-l” into helen’s hand. c. helen copied miss sullivan and made the letters for doll with her hand. d. helen learned to spell many words with her fingers but she did not understand their meaning.
