新PREP1-218

制约与平衡

218.
Only seven people this century have been killed by the great white shark, the man-eater of the movies—less than those killed by 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B
想请教一下比较中关于省略的问题，B应该是省略了people。那么如果用those是不是会产生指代seven people的歧义呢？ 哪位NN能讲讲在比较中如何省略，如何用指代词吗？
我换一个问法吧：如果这句话说成是movies—fewer than those have been对吗？

制约与平衡

这个问题也自己先顶一下吧……
