What did Evelyn Glennie rely on to succeed in music?

Correct answer: Hard work and self-confidence

Evelyn Glennie relied on sustained hard work, determination, and self-confidence to succeed in music. Her increasing deafness created a serious obstacle, but she refused to define herself by that limitation. With guidance from Ron Forbes, she trained herself to sense vibrations and to understand musical sounds in a different way. Her achievement therefore resulted from disciplined practice and a positive belief in her own ability, not from luck or pity. Option A is correct. Option B ignores her years of effort, option C misrepresents her independent achievement, and option D contradicts the entire account because she continued and excelled in music. The lesson presents perseverance as an active choice supported by training.
