Why is has used in the correct choice D?


Because it is a periodic phenomenon, meaning that it is not happening all the time thus when it happens, it allows the warm water that has accumulated up until then, to flow back to east.

Can someone explain the Error in Option C... I know its wrong but can't figure out what it is. Thanks in advance!


C has an incorrect structure: if you eliminate the modifer " the periodic abnormal warming of the sea surface off Peru" you'll see that the word "is" must be present

El Nino, [the periodic abnormal warming of the sea surface off Peru], a phenomenon in which ocean and atmosphere changes combine and which allows the warm water that is accumulated in the western Pacific to flow back to the east.

C looks like this: El Nino a phenomenon in which . There is something missing... like a verb...

Hope it's clear


OK I see "is" is missing here but I think below statement is correct (not related to this problem). Am I correct ?
El Nino, a phenomenon which is highly dangerous, is happening these days.

Thanks

It has to be D.

A, B, C can be eliminated as there is no verb.

between D and E: 'in which' is correct.

+1 for D

A, B, C are missing main verb for El Nino.

E has pronoun reference error.

275. El Nino, the periodic abnormal warming of the sea surface off Peru, a phenomenon in which changes in the ocean and atmosphere combine allowing the warm water that has accumulated in the western Pacific to flow back to the east.

(A) a phenomenon in which changes in the ocean and atmosphere combine allowing the warm water that has accumulated
(B) a phenomenon where changes in the ocean and atmosphere are combining to allow the warm water that is accumulating
(C) a phenomenon in which ocean and atmosphere changes combine and which allows the warm water that is accumulated
(D) is a phenomenon in which changes in the ocean and atmosphere combine to allow the warm water that has accumulated
(E) is a phenomenon where ocean and atmosphere changes are combining and allow the warm water accumulating



Let's start by focusing on subject-verb agreement:

El nino is singular, so we need a singular verb (no omission of is). A/B/C gone because they omit "is" and therefore we do not have a s-v agreement.

D) "in which" is correct, combine is correct, "that has accumulated" is correct. D is correct

E) "where" is incorrect (we are not talking about location), "changes" is incorrect because it only refers to atmosphere; there is no clear connection between ocean and changes. "and allow" sounds weird, "accumulating" distorts the intended meaning of the author. The author does not intend to say that the intent of changes is to accumulate.

D is correct

Any one about usage of HAS in D?

"has accumulated" - Present perfect form is used to refer to the "warm water" that still gets accumulated in the western Pacific but flows back to the east periodically because of the El Nino phenomenon.

has accumulated is a present perfect tense, and is primarily used to depict an event that has happened at some unspecific time before the current time.

Perhaps this can be best understood by few examples:

Now a days, the new Governments always rollback the changes that have been implemented by the old Governments.
- The clause in present perfect (that have been implemented by the old Governments) is modifying changes

Everyday, the Sun clears the mist that has been accumulated by the low temperatures of the night.
- The clause in present perfect (that has been accumulated by the low temperatures of the night) is modifying mist

In El Nino, changes combine to allow the warm water that has accumulated in the western Pacific to flow back to the east.
- The clause in present perfect (that has accumulated in the western Pacific) is modifying warm water

p.s. Our book SC Nirvana discusses Present Perfect tense, its application and examples in significant detail. If you can PM you email, I can send you the corresponding section.

El Nino, the periodic abnormal warming of the sea surface off Peru, a phenomenon in which changes in the ocean and atmosphere combine allowing the warm water that has accumulated in the western Pacific to flow back to the east.

(A) a phenomenon in which changes in the ocean and atmosphere combine allowing the warm water that has accumulated
(B) a phenomenon where changes in the ocean and atmosphere are combining to allow the warm water that is accumulating
(C) a phenomenon in which ocean and atmosphere changes combine and which allows the warm water that is accumulated
(D) is a phenomenon in which changes in the ocean and atmosphere combine to allow the warm water that has accumulated
(E) is a phenomenon where ocean and atmosphere changes are combining and allow the warm water accumulating

Easy one -:

El Nino "is phenomenon" not a phenomenon so A, b and c out

and E phenomenon where ocean : In GMAT, where is used for physical location!!! so D

Can someone explain why "combine" or "to allow" in A and B is not considered a verb?

combine in A and are in B are indeed verbs; but these verbs are only part of dependent clauses; so, there is no independent clause in A and B; and there cannot be a sentence without an Independent clause.

Let's take a simplified example that mirrors A:

James, a married man, an athlete who combines skill and strength enabling him to win medals.

This is not a valid sentence, because the verb combines only appears as a part of dependent clause: who combines skill and strength enabling him to win medals.

One way to fix it would be:

James, a married man, is an athlete who combines skill and strength to enable him to win medals.

Now, we have an Independent clause: James is an athlete

By the way, A and B also have back to back modifiers (the periodic abnormal ... and and a phenomenon in which....), modifying the same entity El Nino. This is not GMAT's stylistic preference.

If there would have been another choice, is a phenomenon in which changes in the ocean and atmosphere combine allowing the warm water that has accumulated

wouldn't that be a correct choice ?

To allow - mentions a purpose of intent. This is a natural phenomenon, and the warm water flow back to east is a result of changes in the ocean and atmosphere, thus allowing should be a better choice.

Please correct me if I am wrong.

this appears cogent reasoning. but then GMAC SC's are more like a beauty contest where u have to select the best out of the lot !! other choices are egregiously wrong so we have to select D.

El Nino, the periodic abnormal warming of the sea surface off Peru, a phenomenon in which changes in the ocean and atmosphere combine allowing the warm water that has accumulated in the western Pacific to flow back to the east.

(A) a phenomenon in which changes in the ocean and atmosphere combine allowing the warm water that has accumulated - Fragment. No verb for El Nino. 'Allowing' must be 'To allow'.
(B) a phenomenon where changes in the ocean and atmosphere are combining to allow the warm water that is accumulating - Fragment. No verb for El Nino. Where modifies only physical places. Present continuous verbs show that actions are still going-on.
(C) a phenomenon in which ocean and atmosphere changes combine and which allows the warm water that is accumulated - Fragment. No verb for El Nino. Act of 'Combine' leads to 'Allowing' hence 'And' is wrong here, it is making them two separate dependent clauses.

(D) is a phenomenon in which changes in the ocean and atmosphere combine to allow the warm water that has accumulated - Correct
(E) is a phenomenon where ocean and atmosphere changes are combining and allow the warm water accumulating - Where modifies only physical places. Present continuous verb show that act of 'combining' is still going-on. No verb for El Nino. Act of 'Combine' leads to 'Allowing' hence 'And' is wrong here, it is making them two separate dependent clauses. Moreover, either 'combining' should be 'combine' to be parallel with 'allow' or 'allow' should be'allowing' to be parallel with 'combiing'.

Kudos please....... :)

I apologize if my behavior has flouted any of the club' rules. But, I asked kudos not for coloring the options...... but for if my explanation would helped somebody to come up with the right answer........Is coloring the solution is wrong (as i do not know all rules for posting) ? If yes, then I will keep that in mind next time.......

Asking kudos or coloring the question is not wrong per Se, unless you give useful insights or a different point of view to solve the question. In other words, an odd angle to look at the question.

Here the only thing I see is nothing of all this. The right choice in green and the wrong ones in red with YES good explanations but there isn't new as discussed before

I hope now is more clear. Anyhow, kudo for encouragement :)

El Nino, the periodic abnormal warming of the sea surface off Peru, a phenomenon in which changes in the ocean and atmosphere combine allowing the warm water that has accumulated in the western Pacific to flow back to the east.

Meaning:
The sentence starts off by talking about El Nino which is a periodic abnormal warming of the sea surface and explains that it is a phenomenon in which some changes allow warm water to flow back to the east.

Error:
1) The subject EL Nino does not have a verb.
2) 'allowing' does not show the purpose of behind why the changes combine. 'to+ verb' must be used.

Let's look at the choices:

(A) a phenomenon in which changes in the ocean and atmosphere combine allowing the warm water that has accumulated
Incorrect

(B) a phenomenon where changes in the ocean and atmosphere are combining to allow the warm water that is accumulating
'where' is used for a place.
Again there is no verb for the subject.
Use of accumulating and combining is incorrect because the sentence presents a phenomenon/ fact and use of ing verb is incorrect to show a fact. We need simple present tense.

(C) a phenomenon in which ocean and atmosphere changes combine and which allows the warm water that is accumulated
Use of which is incorrect.
Again no verb for the subject.

(D) is a phenomenon in which changes in the ocean and atmosphere combine to allow the warm water that has accumulated
Correct answer.

(E) is a phenomenon where ocean and atmosphere changes are combining and allow the warm water accumulating
Incorrect
