Answer:
D. Earlier in the day we had had a tussle over the words "m-u-g" and "w-a-t-e-r." Miss Sullivan had tried to impress it upon me that "m-u-g" is mug and that "w-a-t-e-r" is water, but I persisted in confounding the two. In despair she had dropped the subject for the time, only to renew it at the first opportunity. I became impatient at her repeated attempts and, seizing the new doll, I dashed it upon the floor. I was keenly delighted when I felt the fragments of the broken doll at my feet...I felt my teacher sweep the fragments to one side of the hearth, and I had a sense of satisfaction that the cause of my discomfort was removed.
Step-by-step explanation:
The given excerpt from The Miracle Worker by William Gibson talks about the scene where the child Helen dashed her doll and was forced to be taught the words by her teacher Annie Sullivan. The scene reveals Helen learning the aspects of a "good girl" and "bad girl".
At the same time, option D shows the very same event but from a different perspective. This time, it is from the perspective of the blind girl herself, Helen. She narrates how she was taught the words "mug" and "water" and also the frustration that led to her dashing the doll on the floor. This version of the event is from The Story of My Life by Helen Keller.
Differing perspective is when the same event is told or narrated by different people from different points of view. Thus, the correct answer is option D.
