GMAT Sentence Correction Discussions

Please explain why you pick up an answer. i know the right answer. but i want to know, why is it right so ple explain:

Past assessments of the Brazilian rain forest have used satellite images to tally deforested areas, where farmers and ranchers have clear-cut and burned all the trees, but such work has not addressed either logging, which is the removal of only selected trees, as well as surface fires, burning down individual trees but do not denude the forest.

A. which is the removal of only selected trees, as well as surface fires, burning
B. which removes only selected trees, or surface fires that burn
C. which removes only selected trees, along with surface fires that burn
D. removing only selected trees, or surface fires, burning
E. removing only selected trees, as well as surface fires that burn

Nitin. Says
The Answer is "B" which removes only selected trees, or surface fires that burn. The reason for this is use of right idiom "either--or". This leave us with B and D. B is better as it used simple tense and is parallel.


OA is B and thankyou for the explanation.

Here's one more:

As rare as something becomes, be it a baseball card or a musical recording or a postage stamp, the more avidly it is sought by collectors .
(A) As rare as something becomes, be it
(B) As rare as something becomes, whether it is
(C) As something becomes rarer and rarer, like
(D) The rarer something becomes, like
(E) The rarer something becomes, whether it is

Ple answer with explanation.

In Sentence Correction, the writers of these questions will often try to bait you toward generalization, tempting you to discern the difference between methods of phrasing an obscure idiom or asking you to read a multi-clause, 45-word sentence five different times to see what sounds right. Youre applying to business school, however, not to the editorial desk of the New York Times; your core competencies, as they pertain to grammar, are likely somewhat limited. Accordingly, your goal should be to seek out the errors that you know how to correct, and only worry about others when absolutely necessary (which shouldnt be often, if at all). Consider the question:

Unlike water, which is complimentary, all passengers will need to pay cash for beverages during the transoceanic flight.

(A) Unlike water, which is complimentary--
the use of non-restrictive modifier should make the whole sentence meaningful. in this ques, remove "which is complimentary" and we get:
Unlike water all passenegers will need.... is

(B) Besides water, which is offered free of charge---
besides means in addition to or apart from...so the sentence makes sense: apart from water(which is free) ppl are supposed to pay cash for beverages

(C) Unless the drink is water, which is complimentary-- what does drink in water means??? and anyway such as A-out!

(D) Not like water, which is offered free of charge--hmmm the modifier is fine but changes the meaning of the sentence

(E) With water being the only exception--doesn't make any sense



Thanks Naren. this is a good one :)

C and B are out because of "Like" which somehow suggest that baseball, card are always avidly sought. As rare As should have comparison with other noun, which is missing here so A,B,C are out so Left with E

1. Following 3/2 For AB & CD&E; : Idiomatic as rare as ... This as rare as that .. This is the right way, so we can eliminate B&A; left with ADE...
2. Now Like - Like and Whether, now There has to be a noun so that the continuity exists like Cricket like Football and Volleyball is a Boring Game.. So here Whether looks good.

What we end up messing up here is that as said earlier in this thread also a very common usage when we say if and whether .. Where whether is used for only 2 objects . .However this is an exception πŸ˜‰

thankyou for the explanation. and ya OA is E.
I was able to eliminate all answer choices except B and E an could not understand what's the problem in "As rare As". "the rarer something becomes" sounded weird so chose B. but now understood what's the problem with former.

and can you explain what is 3-2 split?
i know what is POE and use it well. but what is 3-2 split?
i have seen many people use this in their post but don't know what it means.

What 3/2 split is actually process of elimination, what I have seen is that in the majority of the beginner to intermediate levels of questions in the GMAT , we have 3 choices which are nearly/always same. Also now what we see is that here also we can split it into 3:2 that is 2 options
The Rarer something becomes , so now we have a 3:2 split, so here IF Rarer something becomes would have been a clause to say no to the sentence then we would have nver bothered to read E at all. So in majority of places we have splits like this . This question I would rate it as a high difficulty level hence the 3:2 split would have been a tough one . But in some cases you would see that it would be a direct 3:2 split. I hope this makes sense.

Alright πŸ˜ƒ thanks. this makes sense.

what's the OA?


The answer is C. What's so good about this question is that the answer choice that seems the least likely to be the correct answer is indeed the correct answer. Below is the explanation:

The GMAT doesnt explicitly test the preferential difference between complimentary and free of charge, nor does it explicitly test unlike vs. besides. It does, however, test the agreement of modifiers like unlike water, which cannot possibly describe all passengers. In fact, answer choices A,B, D, and E all make the same mistake they attempt to modify passengers with water, which is an illogical comparison. In contrast, answer choice C changes that game, using Unless the drink is water as an independent clause and not a modifier. By doing so, it corrects the modifier error that the others commit, and is the correct answer. Modifiers are one of your core competencies you should attack those whenever and wherever you see them. Seek out these items that fall within your power, and youll efficiently and correctly conquer these sentence correction problems.

Before reading your explanation, read the choices again and it immediately strike me why is C correct! :banghead:
"drink is water" only makes sense !

Usage of Although means, a contrast is made here. and the 1st half of the sentence shows everything happened in the past so we need a past tense to continue the sentence. which is only in E.
But i'm not convinced with E. I find A is better than E.
A says- what has been equally significant ....uses present perfect and indicates that it was significant not only in the past but is still significant.
and that is why "is" before "the invention" makes sense.
I would have marked A.

Ple do tell if there is any mistake in my answer.

Please post your reply with reasoning.

My ans are in bold.

1. Since "Although" is the dependent marker, the second part of the sentence can't have conjuction.

2. "extent to" idiom is used here.

3. "that" conjuction can only be singular here, hence only second option specifies that.



1)Although the invention of the printing press led to a significant reconceptualization of textual production in the fifteenth century, what has been equally significant in the twentieth century is the invention of the computer.

a)what has been equally significant in the twentieth century
b)equally significant in the twentieth century has been
c)no less significant in the twentieth century is
d)what was equally significant in the twentieth century were
e)no less significant in the twentieth century was

2)Scientists are currently trying to determine the extent to which tectonic plates have been shifted from their previous positions by earthquakes and other similar phenomena.
a)to which tectonic plates have been shifted
b)to which tectonic plates have shifted
c)of the shift of tectonic plates
d)of tectonic plates shifting
e)that tectonic plates have been shifted

3)It was anomalies in the orbit of Uranus that led to the discovery of Neptune.

a)It was anomalies in the orbit of Uranus
b)It was the orbit of Uranus showing anomalies that
c)They were anomalies in the orbit of Uranus that
d)The orbit of Uranus being anomalous was what
e)The anomalies in the orbit of Uranus was what

2)Scientists are currently trying to determine the extent to which tectonic plates have been shifted from their previous positions by earthquakes and other similar phenomena.
a)to which tectonic plates have been shifted
b)to which tectonic plates have shifted
c)of the shift of tectonic plates
d)of tectonic plates shifting
e)that tectonic plates have been shifted

extent to is right idiom. Since here "by earthquake is used" so passive form is required. So, I would go with A.

What are the OA?

Hey Mathenthu, can you please post the OA?
I go with B... First I use the 3/2 elimination rule :

Past assessments of the Brazilian rain forest have used satellite images to tally deforested areas, where farmers and ranchers have clear-cut and burned all the trees, but such work has not addressed either logging, which is the removal of only selected trees, as well as surface fires, burning down individual trees but do not denude the forest.
which removes only selected trees, or surface fires that burn ...
1. Either should have or .. Safely elliminate ACE
2. in D removing only selected trees mean , that we don't have a proper particle modifier which modifies the noun logging. This can be done only by using which /that. hence this means we can eliminate D . Always note that when we are seeing something like Noun A, modifier to noun A, then Modifier to noun A should be a particle modifier in majority of the cases. When we select within b/d, we can safely eliminate d



Hi Friend !

I could understand what you are explaining... still need some more theory on "Particle modifier". Would appreciate if you can throw some light on the concept with examples..
