Hello Everyone!

This is a great example of a list question you might find on the GMAT! Let's take a closer look at this question, one issue at a time, and determine our best course of action! First, here is the original question with any major differences between the options highlighted in orange:

Over the next few years, increasing demands on the Chattahoochee River, which flows into the Apalachicola River, could alter the saline content of Apalachicola Bay, which would rob the oysters there of their flavor, and to make them decrease in size, less distinctive, and less in demand.

(A) which would rob the oysters there of their flavor, and to make them decrease in size,
(B) and it would rob the oysters there of their flavor, make them smaller,
(C) and rob the oysters there of their flavor, making them decrease in size,
(D) robbing the oysters there of their flavor and making them smaller,
(E) robbing the oysters there of their flavor, and making them decrease in size,

After a quick glance over the options, a couple things clearly need to be addressed:

1. rob vs. robbing
2. decrease in size vs. smaller


We know already that this is an example of a list question. Whenever we see list questions, we know we must focus on the following:

1. Parallelism (ALL items in the list must be similar in word use, verb tense, structure, etc.)
2. Concision (ALL items should use the most concise wording whenever possible)


The best place to start with any list question is to find any part of the list that isn't underlined. Since that part of the sentence cannot change, ALL other items on the list must match it in verb tense, wording, tone, etc.

Over the next few years, increasing demands on the Chattahoochee River, which flows into the Apalachicola River, could alter the saline content of Apalachicola Bay[/color], [u]which would rob the oysters there of their flavor, and to make them decrease in size, less distinctive, and less in demand.

The two items on the list that aren't underlined are "less distinctive" and "less in demand." Would it make more sense to use "decrease in size" or the more concise "smaller" here? Remember - we must use concise wording whenever possible!

(A) which would rob the oysters there of their flavor, and to make them decrease in size,
(B) and it would rob the oysters there of their flavor, make them smaller,
(C) and rob the oysters there of their flavor, making them decrease in size,
(D) robbing the oysters there of their flavor and making them smaller,
(E) robbing the oysters there of their flavor, and making them decrease in size,

We can eliminate options A, C, and E because they are overly wordy. Saying "decrease in size" and "smaller" mean the same thing. The GMAT prefers you use the most concise option whenever possible, so we have to throw these out.

Now that we're left with only options B & D, let's take a closer look. I've included the rest of the sentence surrounding it so problems might be easier to spot:

(B) Over the next few years, increasing demands on the Chattahoochee River, which flows into the Apalachicola River, could alter the saline content of Apalachicola Bay, and it would rob the oysters there of their flavor, make them smaller, less distinctive, and less in demand.

This option is INCORRECT because it includes a vague pronoun "it." We're not 100% sure what the pronoun is referring to: increasing demands of the Chattahoochee River, the Apalachicola River, or the Apalachicola Bay?

(D) Over the next few years, increasing demands on the Chattahoochee River, which flows into the Apalachicola River, could alter the saline content of Apalachicola Bay, robbing the oysters there of their flavor and making them smaller, less distinctive, and less in demand.

This is CORRECT! It doesn't contain any confusing pronouns, and the parallelism with "robbing" and "making" sounds nice. Also, it uses the concise "smaller" rather than the wordy "decrease in size."


There you go - option D is the best choice!


Don't study for the GMAT. Train for it.


Dear EMPOWERgmatVerbal,

Thanks for the explanation. I am basic in Grammar so, please bear with me for basic questions
I request for detailed explanation of "decrease in size versus smaller"

bb generis GMATNinja

Thanks in advance


Hello priyanshu14!

I'm glad to hear you appreciate the explanations, and don't worry at all about your questions being too simple - they are not at all! Many other students on here are also working on their grammar, so you are not alone!

For this question, there is no difference in the meaning of "decrease in size" versus "smaller." You could use either of them and it wouldn't change the meaning of the sentence. However, when you take the GMAT exam, they prefer that you use short or concise wording whenever you can. Since the phrase you choose is part of a list, it's also a good idea to stick to what the rest of the list looks like. Since the other two items are also written as short as possible, it makes sense to keep them all similar.

to make them decrease in size, less distinctive, and less in demand. = not the shortest/most concise way to say it
to make them smaller, less distinctive, and less in demand. = the shortest/most concise way to say it

Why say 3 words when 1 word will do? That is the main reason we choose "smaller" over "decrease in size."

The only time it would make sense to use "decrease in size" is if it was parallel to the other items in the list. For example, if the list looked like this:

to make them decrease in size, decrease in distinctive markings, and decrease in demand.

I hope this helps! I appreciate you asking, and keep up the great questions!

No, not at all because 'is running' is not a noun. One can't separate 'running' from 'is' and say, running is a gerund (noun) and therefore 'which' can refer to it. It will be absurd to say 'he' is equal to 'running'.

In that case,

He is running. It is a good cardiovascular activity.

This will also be treated as wrong. Coz "it" is a pronoun and can't refer to a verb. Am i right?

If so, how else would you express that sentence grammatically?

Can't we say
1.He is running and running is a good exercie
2.He is practising running, which is a good exercise. In this case running is a gerund and the direct object of the verb
'is practising'. Therfore, it is ok.
3. He goes for a morning run, a good cardiovasculr excercose- Here the term 'run' is a normal noun modified by the appositive 'a good cardiovascular exercise'.

Taha,
In C, two things are wrong. The choice says that river could 'alter and rob' as though 'robbing ' is a separate function done by the river. This is not true. It is the alteration of the saline content of the river that robs the flavor. This is a grave distortion of the original intent. The second point is that the bare infinitive 'decrease in size' is not parallel to the other two adjectives that follow. Smaller is apt

The official explanation of C is the following:
"The comma before the conjunction and signals that an independent clause will follow and, but a verb phrase follows instead. The series of phrases following making them lacks appropriate parallelism."

I understand why C is wrong generally, but got confused by this explanation. Do they mean, an independent clause as a noun+verb structure should follow ',and'?

Hi rencsee!

You are correct - what comes after the ", and" conjunction needs to be a complete thought that includes both a clear subject and verb.

I hope that helps! It sounds like you're on the right track!

First, consider this pair of examples:

  • "Mike went to the grocery store, and bought beer." - The comma shouldn't be there because we are NOT linking two complete thoughts ("bought beer") is not an independent clause.
  • "Mike went to the grocery store, and he bought beer." - The comma is needed because we are linking two complete thoughts (independent clauses, each with its own subject and verb) with a comma+conjunction.

Now consider a stripped down version of choice (C):

  • "Increasing demands could alter the saline content of Apalachicola Bay, and rob the oysters there of their flavor." - This has the same problem as the first example above. The comma+conjunction does NOT link two complete thoughts ("rob the oysters there of their flavor" is a verb phrase and not a complete sentence).

That's all they were referring to in that explanation. And for whatever it's worth, the GMAT very, very rarely uses commas as a major decision point, so I wouldn't spend too much time worrying about them.

I hope that helps!

1 Seismologists studying the earthquake that struck northern California in October 1989 are still investigating some of its mysteries: the unexpected power of the seismic waves, the upward thrust that threw one man straight into the air, and the strange electromagnetic signals detected hours before the temblor.
(A) the upward thrust that threw one man straight into the air, and the strange electromagnetic signals detected hours before the temblor

2. The end of the eighteenth century saw the emergence of prize-stock breeding, with individual bulls and cows receiving awards, fetching unprecedented prices, and excited enormous interest whenever they were put on show.
(C) exciting

3. The most common reasons for an employee’s unwillingness to accept a transfer are that the mortgage rates are high, housing in the new location costs more, and the difficulty of selling the old home.
(E) the high mortgage rates, the greater cost of housing in the new location, and the difficulty of selling the old home

4. Doctors hope that one day the body's master cells called stem cells can be directed to grow in organs or tissues appropriate for transplant, use them to test drugs and potentially toxic chemicals, and may study them to gain insight into basic human biology.

C. transplant, used to test drugs and potentially toxic chemicals, and studied

5. The principal feature of the redesigned checks is a series of printed instructions that the company hopes will help merchants confirm a check’s authenticity, which includes reminders to watch the endorsement, compare signatures, and view the watermark while holding the check to the light.

(E) including reminders to watch the endorsement, compare signatures, and view

Here are five solid GMATPREP questions of list parallelism containing more than two factors in a list. The correct answers to these questions are given in the highlight. All of them have 'a comma plus and' before the last item of the list.

For my update, I am curious to see an official question that mandates a clause after a comma plus coordinate conjunction between the penultimate and ultimate items of a list containing more than three items.

Or perhaps we should not bother about this matter of style too much, concentrating on other errors in the choice as Ninja stated... Because the treatment of making them smaller should not be a modifier of the verb rob,, rather is one more item of the list.
