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

Can someone explain the structure of this sentence?

"Only seven people this century...shark" (main clause)
COMMA+"the man....movies" (Appositive to "shark")
DASH+"fewer than have been...stings" (modifier seven people)


Structure: Main clause, modifier of an item in the main clause, modifier of the subject of the main clause.

1) Is this the right way of thinking about this structure?
2) Can the last modifier be that far away from the intended item?
