I think there is some room for arguments to the answer of this question:
Firefighting numbers among the deadliest professions, a dangerous job which kills hundreds of workers each year.
A) a dangerous job which kills hundreds of workers -- firefighting is killing people?
B) killing hundreds of workers -- same as A
C) a dangerous job in which hundreds are killed -- looks good but a small error.. who is getting killed here? The workers or ordinary citizens?
D) of which hundreds of workers are killed -- Incorrect. First, it modifies deadliest profession and not firefighting. Second, We can say, The ferry was carrying 100 passengers, of which 10 were injured. Here it is says -- the deadliest professions of which hundreds of workers are killed.
E) a job whose danger factor results in hundreds of deaths - "a job..." modifies deadliest profession.Also, wordy.
The OA given by the book was B
But I personally think C would be a better choice. In choice B, the sentence would sound like firefighting kills hundreds of workers each year. This I believe is not what the sentence is trying to convey
A and C both have what we call noun+noun modifier. So it correctly modifies "firefighting"
In A and B both, it looks like that firefighting is killing people.
Ultimately, I ended up eliminating all the choices here
But I can say that C looks better than everything else
What is the source of the question?
