You have a very valid question to ask. One important thing when you read the statement is figuring out the right subject. Now, here in this case, you have "future supplies" and not just "supplies" as a subject. Future supplies can actually take both a singular and a plural verb. But since we have it in the non-underline part of the sentence, we have to believe what is a given.

Can someone help me understand why " future supplies in some of the more arid areas are a concern" is a correct phase. Shouldn't it be "are concerns" instead ? I still got the right answer through parallelism but I want to understand the basic grammatical concept for application on different questions as well.

On a tricky sentence correction such as this one, begin by identifying the main subject, in this case "increasing pressure on water resources" and use it as a reference for all other subjects and verbs in the underlined portion. As written, the sentence states that "the future supply... is a concern". This singular subject is not parallel with the plural noun "water resources", so eliminate choice A as well as choice C that repeats this error. Choice E moves the modifying adjective "future" from before "supplies" to before "concern", thus changing the meaning of the sentence, so eliminate choice E. Lastly, choice B incorrectly uses the pairing modifier "both" with "and" as well as "or", which makes it unclear as to what the list of phenomena "increasing pressure on water resources" includes. The correct answer is D.

I am not able to understand what the highlighted part means. Doesn't the question statement consists of two ICs joined by FANBOYS 'So' ?

Also the 'water resources' is a part of a prepositional phrase and how does it connects to/ impacts 'future supplies' in the 2nd IC?

If you can please help me with my above query?

Thanks

You cannot assume any outside knowledge from a sentence correction, so the only possible anteceding referent for "the supply" is the plural "water resources" even if it is part of a descriptor. I believe that should explain both of your questions, since basically as written "the supply" could refer to anything.

A. both from expanding development, changes in climate, and from pollution, so that the future supply in some of the more arid areas is a concern going forward

B. both from expanding development or changes in climate, and pollution, so that future supplies in some of the more arid areas are a concern

C. from expanding development, changes in climate, and also from pollution, so that the future supply in some of the more arid areas is a matter of concern going forward

D. from expanding development, changes in climate, and pollution, so that future supplies in some of the more arid areas are a concern

E. from expansion of development, changes in climate, and from pollution, so that supplies in some of the more arid areas are a future concern


The Official Guide for GMAT Verbal Review 2018
Practice Question
Sentence Correction
Question no. 270


There are three things in the list:
- expanding development,
- changes in climate,
- pollution

All three should be in parallel.

Also, if you use 'both', it needs to come after 'from', right before listing two elements. e.g. ... from both A and B ...
So the use of 'both from' in (A) and (B) is incorrect.

Only (D) has the three elements in parallel:
... from expanding development, changes in climate, and pollution...

Answer (D)

Hi experts,

Isn't 'future supply.... going forward' redundant in the same sentence and hence we should ignore (A) and (C) for this reason as well ?

PS, An Obvious thing : To improve yourself in SC, REVIEW every mistake in every answer choice after you attempt a problem.

In many of the world’s regions, increasing pressure on water resources has resulted both from expanding development, changes in climate, and from pollution, so that the future supply in some of the more arid areas is a concern going forward.
Another example of parallelism here, the idiom is Both X and Y


A. both from expanding development, changes in climate, and from pollution, so that the future supply in some of the more arid areas is a concern going forward
Both from X,Y and from Z is incorrect.

B. both from expanding development or changes in climate, and pollution, so that future supplies in some of the more arid areas are a concern
Incorrect Y in the Idiom – Both X and Y. Y should start with a preposition.
Both X or Y is unidiomatic.

C. from expanding development, changes in climate, and also from pollution, so that the future supply in some of the more arid areas is a matter of concern going forward
Incorrect Idiom – X and also Y.

D. from expanding development, changes in climate, and pollution, so that future supplies in some of the more arid areas are a concern
Best of All.

E. from expansion of development, changes in climate, and from pollution, so that supplies in some of the more arid areas are a future concern
From X and from Y is unparallel.

Hi Sir, so you are saying the idiom - "from.....to.." the "to" is not necessary? (i.e. We have products ranging from birthday cards to handcrafted jewellery.

OR

the "from expanding development" is a noun phrase?
If Yes, can we form a noun phrase with the word "from"? if i'm not wrong "from" is a preposition, only adjective can modify noun and only adverb/adjective can modify adjective

[quote="AbdurRakib"]In many of the world’s regions, increasing pressure on water resources has resulted both from expanding development, changes in climate, and from pollution, so that the future supply in some of the more arid areas is a concern going forward.


A. both from expanding development, changes in climate, and from pollution, so that the future supply in some of the more arid areas is a concern going forward (both refers only two verbs or noun or phrase eg both A and B)

B. both from expanding development or changes in climate, and pollution, so that future supplies in some of the more arid areas are a concern (both refers only two verbs or noun or phrase eg both A and B)


C. from expanding development, changes in climate, and also from pollution, so that the future supply in some of the more arid areas is a matter of concern going forward ( for the sake of parallelism you either use preposition common for all or use separately for each)

D. from expanding development, changes in climate, and pollution, so that future supplies in some of the more arid areas are a concern

E. from expansion of development, changes in climate, and from pollution, so that supplies in some of the more arid areas are a future concern (same as C)

Errors
both A and B
Parallelism while using A, B, and C

There are certainly cases when "from... to" make sense. For example:

  • "I drove from New York to Boston."
  • "The store sells everything from doughnuts to deep-fried candy bars." :-P

But in other cases "from" is used by itself to indicate the source of something. For example:

  • "A strong odor emanated from the deep-fried candy bar." - What was the source of the odor? The deep-fried candy bar. :-P
  • "Her success resulted from years of hard work." - What was the source of her success? Years of hard work.

That's basically what we have in choice (D): X resulted from Y, where Y is a list of 3 things: 1) expanding development, 2) changes in climate, and 3) pollution.

I hope that helps!
