Someone posted an excellent explanation above explaining why it is inappropriate to end the sentence with a preposition (although I mistakenly do it all the time).
The “to” is part of the relative clause that is modifying “dioxins”.
Cutting down (B) to a smaller sentence.
-come from X. (“come” is the working verb for “dioxins”)
It’s not a sentence fragment, but it is wrong none the less.
Quote:
A report by the American Academy for the Advancement of Science has concluded that much of the currently uncontrolled dioxins to which North Americans are exposed comes from the incineration of wastes.
(A) much of the currently uncontrolled dioxins to which North Americans are exposed comes
(B) much of the currently uncontrolled dioxins that North Americans are exposed to come
(C) much of the dioxins that are currently uncontrolled and that North Americans are exposed to comes
(D) many of the dioxins that are currently uncontrolled and North Americans are exposed to come
(E) many of the currently uncontrolled dioxins to which North Americans are exposed come

Thanks for response sir.
But,
B says: much of the currently uncontrolled dioxins to come from the incineration of wastes.
C says: much of the dioxins to comes from the incineration of wastes.
D says: many of the dioxins to come from the incineration of wastes.
The preposition (to) after the word 'dioxins' makes the sentence fragment! Is my thinking wrong?
Your thinking is wrong. You have failed to consider some key words in the sentence.

I want to know one more thing about choice E.
What does the word 'exposed' play role in choice E? Is it 'verb' or 'adjective'?
It's part of the verb "are exposed." It is a
past participle, which in a way works adjectivally, but it's also part of the verb form.
MartyTargetTestPrepThank you sir for quick reply.
If 'exposed' is the 'past participle' then '
'North Americans are exposed'' is a passive voice, right? There is nothing like 'exposed
to'' in the Cambridge dictionary-at least I did not find any words like that one! So,
to is not the part of 'exposed', I think. So, if we remove ''North Americans are exposed'' from the core, then we still get
to before
come(s) in choice B, C, and D which makes those choice fragment!
I don't know what's going on in my brain!
