Question 13

Which statement best describes the central idea of the text?



A. Acoustical engineers often use concrete for the outer walls of concert halls.

B. The design of concert halls accounts for many factors that affect sound quality.

C. Sound travels better in an empty room than in a crowded room, which is why concert halls have limited seating.

D. Acoustical engineers care more about sound quality in concert halls, while architects care more about their appearance.

Answer 1

B

The passage's main point is that concert-hall design involves many factors that affect sound quality (materials, shape, seating, occupancy, etc.). A is too specific, C is incorrect, and D is an oversimplified contrast rather than the central idea.
