Official Guide 2013 - Sentence Correction - Q#83

27. 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

I was able to arrive at the answer. But in the process I got some doubts:
1. of the currently uncontrolled dioxins ... comes -> here the subject dioxins lies inside the prepositional phrase
2. to which North Americans are -> here the subject North Americans lies inside the prepositional phrase

Usually we should not consider the subjects lying inside the prepositional phrase; however here we are considering. Kindly help to explain.


Hi Arun,

Thanks for posting your doubt here. :-)

1. In the correct answer choice E, the subject for the verb come is many of the currently uncontrolled dioxins. Essentially, the subject for this verb is many. Since many refers to more than one, it correctly takes plural verb come.

2. to which is not a typical prepositional phrase. Look at it this way. A relative pronoun modifier always starts a dependent clause. The relative pronoun modifier itself can be the subject of the DC it starts or can a have separate SV pair. In this particular choice, the relative pronoun modifier which starts a DC but does not act as the subject of the DC it starts. The subject of that DC is North Americans that correctly takes the verb are.

Hope this helps. :-)
Thanks.

I have doubt on Dioxins part, as a person from commercial background, I have no clue about types of Dioxin and so I would simply conclude it as a pollutant causing harm; Just like we treat something like carbon monoxide. Now, constructing a sentence using "many" to refer to carbon monoxide will make it awkward. How to identify issue in such a case, as answer to this question would be obvious only to the ones who know that there are various kinds of Dioxin.

Thanks,
Sumit

Rest assured, the GMAT does not require a strong background in chemistry. Certain GMAT Club experts (*cough*) would be in big trouble if it did. :-)

It's enough to know that "many" refers to countable nouns and "much" refers to uncountable nouns. And if the noun is plural, it has to be countable, right? So the presence of the plural "dioxins" is enough to indicate that "many" is appropriate here.

You're absolutely correct that carbon monoxide is non-countable, but there's no rule that says that pollutants must always be non-countable. It just depends on the specific pollutant in question. The same is true for all sorts of other categories of nouns. Foods, for example, could be either countable ("chips" or "deep-fried Twinkies") or non-countable ("okra" or "oatmeal").

I hope that helps!

When do we decide whether the intended meaning is regarding the "amount of something" or "the particular item itself".

There are several official questions where much of ... Is used with plural nouns to show that the amount of something is talked about.

Please clarify my doubt. With examples would be a bliss

I don't understand how people made mistake in this. This should be a sub 600 not 700 sc.

It is simple
Much vs Many(Countable noun many - dioxin 1dioxin, 2 dioxins etc)...
come vs comes.

Many people comes?--- Wrong
Much people comes?--- Wrong

Many people come--->Right
