In the Gulf of Mexico's 'dead zone,' every summer aquatic life is smothered in an area as large as the state of New Jersey, which, according to scientists, is caused by excess nitrogen flushed down the Mississippi River.

A) which, according to scientists, is caused by excess nitrogen flushed down the Mississippi River.
Here which referring to New Jersey, which is not caused by excess nitrogen.


B) which scientists say is caused by excess nitrogen flushed down the Mississippi River.
Here which referring to New Jersey, which is not caused by excess nitrogen.
C) the cause of which, according to scientists, is excess nitrogen flushed down the Mississippi River.
Leave for the time being.
D) the cause of which is excess nitrogen flushed down the Mississippi River say the scientists.
Here subject of verb say is "the cause of which is excess nitrogen flushed down the Mississippi River" ; lets replace this with We so sentence is we say the scientist. So ""the cause of which is excess nitrogen flushed down the Mississippi River" is not saying anything to scientist.
E) that comes from the flushing of excess nitrogen down the Mississippi River, according to scientists.
Here "that comes from the flushing of excess nitrogen down the Mississippi River" is acting as a essential modifier so sentence is missing verb.

I hope my explanations helps.

Thanks rphardu. I got the point that i was missing.. 'which' wrongly referred to New Jersey and hence a wrong choice.

stuff like this is easy once you see the silly mistakes you overlook. I almost chose A. But double back when I realized A and B are very similar.

Expert's post
There is something that is not congruous in rphardu’s thesis about the choice D. To call "the cause of which is excess nitrogen flushed down the Mississippi River" as the subject of the sentence is off the mark in the least. The actual parsing of the sentence is “Scientists say the cause of which is excess nitrogen flushed down the Mississippi River” in which case, the subject of the verb ‘are’ is simply ‘scientists’ and the phrase ‘the cause of which blah, blah’, the object. The phrase 'the cause of which' has no more function than to act as a benami for the relative pronoun ‘which’ and is used to circumvent the touch rule of relative pronouns. So I do not find anything grammatically wrong with D. But D is logically wrong because, nowhere in the original the passage, it is said that the scientists say this or that. It simply states ‘according to scientists’, which choice C religiously reproduces. That is the reason IMO C is better than D.


E is wrong because, when read along with the un-underlined previous part , the choice seems to say that New Jersey comes from the flushing; This is just akin to choice A and B which are wrong for using ‘which’ flouting the touch rule

But how does an essential modifier lead to the missing the verb in E?
