Hi Skywalker18!

This is really tricky, because both C and E use parallel structure correctly (as has been pointed out by others above). So it's hard to differentiate between the two. However, the reason that we choose E over C is that in choice C we have:

a switch to renewable sources of energy for maintaining current levels

This is a case where we want an infinitive of purpose -- we are describing the purpose of something. It is incorrect to use "for" here -- we need to say "to maintain". It is not acceptable to substitute a [preposition] + [gerund] (like "for maintaining") for an infinitive of purpose. So for that reason, we eliminate C and choose E.

Hope that helps! :-)

I think C is incorrect because the false use of "for". "To" seems to be the better fit there.

However, I am aware that the construction in E with "are containing" doesn't appear to be parallel, but it still appeared to be the preferable option over answer choice C.

Perhaps, one of the experts can shed some light on this question :)

Hi aaba,

Another great question! Let's tackle this one problem at a time, and determine how to get to the correct answer quickly!

The first thing we notice when looking at the answers quickly is how they begin: by proposing vs. propose. Since this is a comparison (one group believes X, while "others" believe Y). Using the phrase "by proposing" makes it sound like we're only talking about one group, not 3. So let's eliminate answers A & B because they don't convey the right meaning.

Now that we have it narrowed down to 3 possible answers, let's look at parallel structure - the most common grammar problem in GMAT questions that contain lists. For this question, the following need to be parallel:

others X / and still others Y

To make it easier to spot, I'll add the word "others" to the beginning of each phrase and highlight the two parts that need to be parallel:

C: others propose a switch to renewable sources of energy for maintaining current levels, and still others contend

Answer C does use parallel structure, but there is another problem with this answer: the phrase "for maintaining current levels." By doing this, it's unclear if the energy or the proposal will maintain current levels. Since it's unclear, this is INCORRECT.

D: others propose a switch to renewable sources of energy to maintain current levels, and still others by contending

Answer D is INCORRECT because it doesn't use parallel structure.

E: others propose switching to renewable sources of energy to maintain current levels, and still others are contending

Answer E is CORRECT because it uses parallel structure and clear language.

I still don't understand how answer E maintains parallelism. And you have not addressed that issue either, you have simply stated that it uses parallel structure.

Hello GMATNinja,

Sire, in this how is option E parallel and C not parallel.

I agree in option C "for maintaining" is wrong - we need "to maintain" to show purpose - but there is bigger issue, parallelism, in E than C.

Argue ..., propose ... and contend --> Nice parallel structure - C
Argue ..., propose ... and are contending --> Doesn't look nice - E

--Why do we need a present continuous when simple present does the job perfectly?

Please throw some light on this issue.

I have the same question, how is E maintaining parallelism? And isn't parallelism a bigger issue than "for maintaining" if we have to make a choice? Can experts please help?

E: While many argue...., others propose...., and still others are....

Parallelism is between the 3 verbs in bold above.

C propose a switch to renewable sources of energy for maintaining current levels, and still others contend - for maintaining does not show purpose

E propose switching to renewable sources of energyto maintain current levels, and still others are contending -

Both options C and E have parallel structure as indicated by the bold faced verbs. For parallelism to hold it is not necessary to have same tense of the verb.
But option E is preferred over C just because it uses infinitive to correctly show purpose.

Is this understanding correct, experts kindly comment.
Thanks in advance!

While many argue that we must reduce our dependence on fossil fuels by spreading greater awareness about conservation and waste, others by proposing switching to renewable sources of energy to maintain current levels, and still others by contending that nuclear power is the best way to meet our energy needs.

- meaning : WHILE (indication that following clause will be contrasted) many argue....(so author is going contrast this group's argument...
"other by proposing" ...here contrast is not clear and ungrammatical ...this is false parallelism ...it should be "other propose" as we need a cpontrast
"and other by contending" ..so here is one more contrast to the"many argue" ...but again we have a false parallelism..we need a verb (contend/are contending)

grammar error : we need a verb to contrast a verb ..so "by proposing"is wrong ..therefore A and B are gone

(C) propose a switch to renewable sources of energy for maintaining current levels, and still others contend
- maintains parallelism
- clean and clear
-BUT BUT BUT the structure "for maintaining"is wrong here...
I'll elaborate on this more : "to + verb " is used to show the purpose of the preceding element
here other are proposing a switch to renewable sources ! why are they proposing this??? what is the purpose??? - TO MAINTAIN current levels
"for + verbing" is used when we are denoting ownership or what we obtained from doing something. for eg: I recieved an award FOR devoting my life to philanthropy. ... " I thank the Gods FOR blessing me with such friends" ..here you cannot use "to +verb" because you are not getting something because of thanking to the gods ...you already got the firnds and then you are thanking..similarly I am recieving an award after i did philanthropy not because i am goung to recive an award I will do philanthropy..
Short story :
"to +verb" : use this to show a purpose for doing something ...you are doing it for a reason .
"for+ verbing" : the structure AFTER "for verbing" is the actual thing you did BEFORE . That is the structure after "for verb" is done before the structure before the "verbing"
here if we use "for maintaining" what we mean is we first maintain and then we propose a shift.

(D) propose a switch to renewable sources of energy to maintain current levels, and still others by contending
-Not parallel

(E) propose switching to renewable sources of energy to maintain current levels, and still others are contending
- This may seem unparallel but there is no such compulsion that all the verb must be in the EXACT same state . As long as the event are still in PRESENT it is okay... "are contending" is present continuos and "propose" is present. We could easil;y mean that others propose and other are contending...
the main point here is "to+verb" this tells us the reason why the action (propose) has to be done ...
The structure after "to vebr"is the later achievement/goal...but the structure before "to verb" is something we have to do first
this is exactly opposite to "for vebring" where the later structure is done first and the former structure is the something you get in return.

If any doubts persist lemme know

This is not a genuine GMATPrep question.

This is a simulated version of an original OG 10 topic as given below.

Quote:
https://gmatclub.com/forum/while-some-propose-to-combat-widespread-illegal-copying-of-computer-151395.html

While some propose to combat widespread illegal copying of computer programs by attempting to change people's attitudes toward pirating, others by suggesting reducing software prices to decrease the incentive for pirating, and still others by calling for the prosecution of those who copy software illegally.


(A) by suggesting reducing software prices to decrease the incentive for pirating, and still others by calling

(B) by suggesting the reduction of software prices to decrease the incentive for pirating, and still others call

(C) suggest the reduction of software prices for decreasing the incentive for pirating, and still others call

(D) suggest the reduction of software prices to decrease the incentive for pirating, and still others by calling

(E) suggest reducing software prices to decrease the incentive for pirating, and still others are calling

Ans E:

MGMAT's comments f


While some propose to combat widespread illegal copying of computer programs by attempting to change people's attitudes toward pirating, others by suggesting reducing software prices to decrease the incentive for pirating, and still others by calling for the prosecution of those who copy software illegally.

A)by suggesting reducing software prices to decrease the incentive for pirating, and still others by calling

B)by suggesting the reduction of software prices to decrease the incentive for pirating, and still others call

C)suggest the reduction of software prices for decreasing the incentive for pirating, and still others call

D)suggest the reduction of software prices to decrease the incentive for pirating, and still others by calling

E)suggest reducing software prices to decrease the incentive for pirating, and still others are calling

The parallel verbs are some PROPOSE (to combat), SUGGEST (reducing), and ARE CALLING (for X). All three verbs are in the present tense (although the third is in the present progressive, it's still considered present). If I could wave a wand, I would choose to make the third verb CALL, not ARE CALLING, but I don't have that option while retaining correct grammar in the rest of the sentence (e.g., in choice C, the expression "for decreasing" is definitely incorrect -- you must express the intended result of "reducing software prices" with an INFINITIVE such as "to decrease").

Now you can use the same logic to the given question and see whether it is ok to take E as the most parallel in the given context.

The Takeaway: Lot of questions are doing the rounds as GMATPrep questions, I don't know what for. Incidentally, the original PG 10 question does not seem to have been carried over in subsequent versions.

How is others propose and still others contend.... the wrong parallelism?
both propose and contend are verbs correctly addressing plural others
