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
Only seven HAVE BEEN KILLED by Animal A- less/fewer than HAVE BEEN by Animal B.
C,D and E are out because "which", "a number", "fewer" touch the movies. By touch rule, these phrases modify the movies. This is incorrect.
Now, we are left with A and B. We need to maintain parallelism and only B uses HAVE BEEN...
Impossible is nothing to God.
