Answer:
The correct answer is Helen Keller made an important connection when she learned to spell the word “water” into her teacher’s hand.
Step-by-step explanation:
The question refers to Helen Keller, who was an American writer and the first deaf-blind person to get a Bachelor of Arts degree; the sentence refers to the first time Keller spelled a word into Annie Sullivan's hand, her teacher and life companion. The correct answer is the first one because the quotation marks indicate what the word spelled was (water) but without them it is confusing.
