How did Evelyn Glennie train her body to feel sound?

Correct answer: Sensitive to sound

The governing concept is sensory adaptation. Because Evelyn could not depend on ordinary hearing, she trained herself to notice vibrations through her skin, feet and other parts of the body. With guidance and persistent practice, she learned to distinguish different sounds by sensing how vibrations travelled through surfaces and her body. Thus option A is correct: she made her body sensitive to sound vibrations. The other choices describe withdrawal or inactivity, which contradict the account of her active training. Her achievement does not mean that she ignored music or focused only on books; instead, she developed a new physical and mental way to experience music.
