Quote:
(A) a phenomenon most scientists agree to be caused by human beings in burning fossil fuels,

So if you’re a regular visitor to the verbal forums, you might have noticed that we’re banging away at a theme: if you aren’t strict and literal with the meaning of these sentences, you’re toast. We said a lot about that in our beginners’ guide to SC, and it’s also been a theme in our QOTDs (all of which are available here).

And this is another example of it! The phrase “human beings in burning fossil fuels” sounds like the human beings are... um, in a fiery tank of coal or oil? That sounds unpleasant. Plus, I’m not sold on the phrase “most scientists agree to be caused.” Seems like “is” would be better than “to be” here. Either way, (A) is out.

Quote:
(B) a phenomenon most scientists agree that is caused by fossil fuels burned by human beings,

Hm, the modifier “that is caused by fossil fuels” seems misplaced. It could be OK to say “scientists agree that X is true”, but we’re trying to modify the phenomenon here: “a phenomenon that is caused by fossil fuels” seems fine, but I can’t make sense of this one.

If you wanted to be conservative, you could hang onto (B) for now, but we’ll have a better option in a moment.

Quote:
(C) a phenomenon that most scientists agree is caused by human beings’ burning of fossil fuels,

Pardon my language, but this sounds awkward AF. That’s not a crime, though. (See beginners’ guide to SC, for more on why “awkwardness” shouldn’t be your first worry.) And I can’t see any DEFINITE errors here. The “that” modifier is OK, and I guess I’m cool with the possessive “human beings’ burning of fossil fuels.” I don’t like it. But the GMAT doesn’t care what I like. The meaning makes sense: human beings’ act of burning fossil fuels is indeed the thing that causes global warming.

(C) isn’t wrong. Keep it, perhaps while holding your nose.

Quote:
(D) which most scientists agree on as a phenomenon caused by human beings who burn fossil fuels,

(D) arguably sounds better than (C), but (D) messes up the meaning. Rearranging slightly, (D) is saying that “scientists agree on global warming as a phenomenon caused by human beings who burn fossil fuel.” First, it would make sense to say that scientists agree that global warming is a phenomenon caused by human beings, but scientists agree on it as a phenomenon isn’t right: that’s basically saying that scientists agree that it’s a phenomenon, but that’s pretty meaningless.

Second, it’s awfully weird to say that global warming is “caused by human beings who burn fossil fuel.” The act of burning fossil fuels causes global warming – not “human beings” who happen to burn fossil fuels.

I can’t totally fault you if you picked (D) over (C), but the meaning is much clearer in (C). I’d cross out (D).

Quote:
(E) which most scientists agree to be a phenomenon caused by fossil fuels burned by human beings,

The argument is similar for (E) as for (D), except that “agree to be a phenomenon” is a completely wacky phrase that makes even less sense than “agree on as a phenomenon.” And in (E), global warming is caused by the fossil fuels themselves, and that’s not quite right: it’s caused by human beings’ act of burning fossil fuels. So (E) warps the meaning, too.

We’re left with (C). I don’t like it, either. But it does a better, clearer job of conveying the meaning than any of the others.

I would go with answer choice (C). answer should contain " a phenomenon that is caused by the burning of fossil fuels". Not by human beings or by fossil fuels.
Hope this help !

(A) a phenomenon most scientists agree to be caused by human beings in burning fossil fuels,-----"human beings in burning..."does not properly presents the action of human beings. it's an awkward construction

(B) a phenomenon most scientists agree that is caused by fossil fuels burned by human beings,--------this is a passive construction and the use of "burned" signifies that the action happend in the past and is not continuing but that is not correct. the action of burning is continuing, hence it will create problems in future

(C) a phenomenon that most scientists agree is caused by human beings' burning of fossil fuels,------Correct. the action of human being's is correctly presented

(D) which most scientists agree on as a phenomenon caused by human beings who burn fossil fuels,-----this changes the meaning of the sentence. now instead of a generic effect, the blame is only on human beings who burn fossil fules

(E) which most scientists agree to be a phenomenon caused by fossil fuels burned by human beings,-----same error as B

Hello mrittik800,


The original sentence intends to say that global warming has been caused because human beings burn fossil fuels.

However, Choice B suggests that global warming has been caused by fossil fuels. The modifier burned by human beings only provide additional information about fossil fuels. But the main cause for global warming is fossil fuels per Choice B.


Hope this helps. :-)
Thanks.
Shraddha

The World Wildlife Fund has declared that global warming, a phenomenon most scientists agree to be caused by human beings in burning fossil fuels, will create havoc among migratory birds by altering the environment in ways harmful to their habitats.

(A) a phenomenon most scientists agree to be caused by human beings in burning fossil fuels,
(B) a phenomenon most scientists agree that is caused by fossil fuels burned by human beings,
(C) a phenomenon that most scientists agree is caused by human beings' burning of fossil fuels,
(D) which most scientists agree on as a phenomenon caused by human beings who burn fossil fuels,
(E) which most scientists agree to be a phenomenon caused by fossil fuels burned by human beings,

The correct sentence is c. This is a case of Noun + Noun modifier. A phenomenon is modifying global warning and that clause which immediately follows a phenomenon talks more about the phenomenon.

A is wordy and has a meaning error.
B again has a meaning error, it incorrectly implies that global warming is caused by fossil fuels.
D has the same meaning error. Yes, it is caused by human beings but how it is done by them is not clearly stated.
E is wordy and awkward.

Please comment if my explanation has any error.

Thank you

To make life simple, the fact is that Global warming is caused individually neither by human beings nor by the fossil fuels, but by a combination of human beings' burning of the fossils. This combination is stated only in C.

Hello KB04,

You have done a good job at solving this official sentence.

You have stated correct reasons to reject incorrect answer choices.

I would just like to say that Choice E has the same error as Choice B as this choice also says that that fossil fuels cause global warming.

Rest all is good.

Hope this helps. :-)
Thanks.
Shraddha

Hi experts.
I crossed out C immediately after seeing human beings' burning. That did not make sense to me. I thought it means burning of human beings. Eg. Smiths' house means the house of Smiths. Mark's register means the register of marks.
I also had an issue here with regard to the modifier. Because as far as I know, any clause beginning with , modifies the entire previous clause, I am not sure why which is not important in this sentence.
And in D, I thought agree on as a phenomenon is wrong because agree on something means an agreement where two or more parties are arriving at a consensus eg. We all agree on this point. Further, agree on as a phenomenon - as a phenomenon? Well, scientists are not a phenomenon, because as is used for comparison or for function.

Regards,
