题目是:Only seven people this century have been killed by the great white shark, the man-eater of the movies—less than those killed by the bee stings.
A. movies—less than those
B. movies-fewer than have been
C. movies, which is less than those
D. movies, a number lower than the people
E. movies, fewer than the ones
答案是选E,我想问一下破折号后面的东西是修饰什么的? 这里less than是修饰movies呢? 还是修饰only seven?
