'are exposed to come' is weird...., additionaly, 'currently uncontrolled dioxins' is better in comparison to 'dioxins that are currently uncontrolled'

(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
D is wrong because of "and"
due to and the sentence sounds like this
many of the dioxins that are currentrly uncontrolled are exposed to come...AND
many of the dioxins that are north American are exposed to come..

I hope its clear..

Many - countable Items
Much - Uncountable Items

I think answer as posted by goelmohit2002 is B and not E.
And "much , many " explanation is correct.

the latter is a wordier form of the former. (shorter is better provided it makes sense)

Hi Scooby,

Thanks. the reason OG says to kick out D is that "D requires that before North Americans, to be grammatically complete".....

Can you please tell why that is required ? as per my understanding it is not necessary to have "that" in the second item of that list....

i.e. as per my understanding "Report concluded that X and Y" is grammatically correct....

yes we need "that" before Americans for parallelism in D.

many of the dioxins that are currently uncontrolled and (many of the dioxins) that North Americans are exposed to come

we must make sure both sides of "and" are "that clauses"

OG question, which means I can only give a brief response. Also, please remember to include the source in your original post of a problem. The instructors aren't supposed to respond unless / until a source is given! (Someone else mentioned it further down in the thread.)

I was asked to address why D is wrong.

A report... has concluded that many of the dioxins that are currently uncontrolled and North Americans are exposed to come from Y

the "and" indicates parallelism. Logically and structurally, we'd expect "N.A. are exposed to" to be parallel to "are currently uncontrolled." Each item is about "dioxins":

many of the dioxins are currently uncontrolled
many of the dioxins North Americans are exposed to

Logically, they're okay, but structurally, they're not parallel.

Now, in this case, we would also want to insert the word "that," as others have mentioned above. Although we don't always have to insert the word "that" for the 2nd item, in this case, the sentence is complex enough that the addition of the word "that" for the 2nd item would actually help to make the structure more clear.

Although I still think it wouldn't be a good sentence, because we'd then have three "that" words in there! Awkward and potentially confusing (would the third "that" be parallel to the first or second?). Notice how the correct answer basically totally changes things around at that part of the sentence, compared to D.

(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
If you say dioxins uncontrolled...and exposed"= 2 verbs so to mantain parallelism shoud use that...+that
E is ok as is only one verb

Hi @beatItWillYou,

I think you are getting confused between the two usages of "that" - that as relative pronoun and that as demonstrative pronoun. When "that" is used as a relative pronoun, it is always used in singular form regardless of whether it refers to a singular noun or a plural noun. However, when it is used as a demonstrative pronoun to identify a noun entity, "that" is used to demonstrate a singular entity and "those" to demonstrate a plural entity. For example:

Bank of America offices are in those buildings that are east of the traffic signal.

In this sentence, "those" demonstrates or identifies the plural noun "buildings". And hence is plural. However, pay attention to "that". It refers to the plural noun buildings but is used in singular form. It basically provides additional information about the buildings through the dependent clause "that are east of the traffic signal".

Hope this helps clarify your confusion. I suggest you search online and read up some reference material on these two kinds of pronouns. This will further help cement the difference in your mind. In addition, you may review "Pronouns" concept in the free trial of e-GMAT SC course. To access free trial, register here . You may view a help video here .
