Which is the most precise central idea of the chapter?

Correct answer: Dedicated music turns both personal limitation and cultural limitation into respect

Option A is the most precise central idea because it brings together the different challenges and achievements in both parts of the chapter. Evelyn Glennie faces a personal limitation involving hearing, yet dedicated musical training enables her to become an internationally respected performer. Bismillah Khan works within a traditional musical world and elevates the shehnai from a comparatively limited ceremonial association to a respected classical instrument. In both cases, music transforms an apparent boundary into dignity, recognition, and respect. Option B reduces music to entertainment, ignoring its artistic and cultural power. Option C denies the role of effort, and D misreads tradition because Bismillah Khan shows that tradition can grow through creative mastery. Thus A is comprehensive without being vague.
