(B) While the cost of running nuclear plants is about the same as for other types of power plants, the fixed costs that stem from building nuclear plants make the electricity they generate more expensive.

(C) Even though it costs about the same to run nuclear plants as for other types of power plants, it is the fixed costs that stem from building nuclear plants that makes the electricity they generate more expensive.

(D) It costs about the same to run nuclear plants as for other types of power plants, whereas the electricity they generate is more expensive, stemming from the fixed costs of building nuclear plants.

(E) The cost of running nuclear plants is about the same as other types of power plants, but the electricity they generate is made more expensive because of the fixed costs stemming from building nuclear plants.

(A) While it costs about the same to run nuclear plants as other types of power plants, it is the fixed costs that stem from building nuclear plants that makes it more expensive for them to generate electricity.

Hm, there’s some weird pronoun stuff going on here. The first “it” is a non-referential pronoun: in the phrase “it costs”, “it” doesn’t refer to anything at all. It’s sort of like saying “it is raining” or “it is a bad idea to lick frozen doorknobs.” (I may or may not speak from experience on that last one.)

Non-referential pronouns can be fine, but you don’t see them very often in correct GMAT answers, so they make me nervous.

And of course, there are three of those non-referential pronouns in the sentence! Both “…it is the fixed costs…” and “makes it more expensive” have non-referential versions of “it.” I can’t call them DEFINITE errors, but I don’t love them, and I can’t imagine that a correct GMAT sentence would have THREE non-referential pronouns. Non-referential pronouns just aren’t that awesome, and there’s no good reason to overuse them.

I also see no reason to use “them” toward the end of the sentence: why say “makes it more expensive for them to generate electricity” when you could just shorten it to “makes it more expensive to generate electricity”? Wasted words aren’t cool.

And if you’re not convinced by any of that stuff, there’s a wonderfully serious mistake in (A). “…the fixed costs… makes it more expensive…” That’s a clear subject-verb error.

I’m tired of (A) now. Let’s eliminate it.

Quote:
(B) While the cost of running nuclear plants is about the same as for other types of power plants, the fixed costs that stem from building nuclear plants make the electricity they generate more expensive.

I don’t see any major issues in (B). The pronoun “they” jumps out at me, and it seems to refer to the nearest plural, “nuclear plants.” And that works just fine: “the fixed costs that stem from building nuclear plants make the electricity [nuclear plants] generate more expensive.” No problem.

The only other potential objection I see is the comparison at the beginning of the sentence, but… hang on, it’ll be easier to explain WHY that comparison is OK if we put it side-by-side with another answer choice.

So for now, let’s keep (B), and I’ll say more about the comparison at the end of this post.

Quote:
(C) Even though it costs about the same to run nuclear plants as for other types of power plants, it is the fixed costs that stem from building nuclear plants that makes the electricity they generate more expensive.

(C) has a few of the same problems we saw in (A). The subject-verb problem is the biggest issue: “the fixed costs… that makes” is definitely wrong.

We also have a couple of non-referential pronouns in the phrases “it costs about the same” and “it is the fixed costs…” These aren’t WRONG, exactly, but there’s no compelling reason to include them in the sentence unless they somehow clarify the meaning. For more detail, please see the explanation for (A).

But even if you’re OK with the funny non-referential pronouns, the subject-verb thing lets us eliminate (C).

Quote:
(D) It costs about the same to run nuclear plants as for other types of power plants, whereas the electricity they generate is more expensive, stemming from the fixed costs of building nuclear plants.

(D) is just plain old confusing. For starters, the pronoun “they” logically needs to refer to “nuclear power plants”, since we know from the context (“stemming from the fixed costs of building nuclear plants”) that the nuclear plants generate more expensive electricity. But “they” is actually closer to “other types of power plants.” That’s confusing – and probably a good enough reason to eliminate (D).

Plus, I still don’t see any good reason to use a non-referential pronoun (“it costs…”) at the beginning of the sentence. See the explanation for (A) for more detail on this.

So (D) is out.

I promised that I’d come back to the comparison in (B), so here it is again, right next to (E):

Quote:
(B) While the cost of running nuclear plants is about the same as for other types of power plants, the fixed costs that stem from building nuclear plants make the electricity they generate more expensive.
(E) The cost of running nuclear plants is about the same as other types of power plants, but the electricity they generate is made more expensive because of the fixed costs stemming from building nuclear plants.

The comparison error at the beginning of (E) is pretty darned subtle: “the cost of running nuclear plants is about the same as other types of power plants…” Wait, no. We’re trying to compare the COSTS of running the two types of plants, but (E) literally compares the costs of running nuclear plants to the other plants themselves. That doesn’t work.

The version in (B) (“the cost of running nuclear plants is about the same as for other types of power plants”) might not be perfect, but it’s definitely better: the use of the preposition makes it clear that we’re comparing the costs of running nuclear plants with the corresponding costs “for other types of plants.” Fair enough.

You could also argue that the second half of the sentence is clearer in (B) than in (E). (B) is in active voice and more direct: “the fixed costs… make the electricity… more expensive.” (E), on the other hand is passive: “the electricity… is made more expensive because of the fixed costs stemming from building nuclear plants.” (E) isn’t necessarily WRONG in this section, but it’s definitely not as clear and direct as (B).

So (B) is our answer.

IMO, this is quite a bad question. Because arguably, the "they" in B is ambiguous. Both costs and nuclear plants are plural, so there is definitely room for confusion.
The pronoun "they" in D clearly refers back to power plannts, there's no pronoun ambiguity there. Sure, the present participle "stemming" modifies the whole preceding clause but I don't see why that's a problem, what's "stemming" is, in fact, the expensive electricity, so I don't see where the modifier error is.
All in all, this question is just confusing..

Dear aeglorre,
This is a high quality question, SC #107 from the OG13. Yes, it's one of the harder questions in the OG, probably a question that many test takers would get wrong, but it is a very solid question, as are all the questions in the OG. The questions in the OG of such high quality that all other practice questions are striving to reach that level. If I may give you some advice, it usually doesn't reflect well on a student who argues that an OG question is of low quality.
In choice (B)the subject of the sentence unarguably is "nuclear plants." This rhetorical focus, as well as the logic of the context, makes the antecedent of the pronoun "they" completely unambiguous.
You're correct, in (D), "stemming" begins a dangling modifier. Choice (D) is clearly wrong, and choice (B) is clearly correct.

-Some people say "they" or "it" is wrong, others say it's right.
-There's this topic of "emphatic construction"
Also, I'm still pretty confused on the use of "for" in B versus the wrong answers. Can someone please elaborate on that?
Thank you!!

Dear SleeB,
First of all, about emphatic construction, see:
http://magoosh.com/gmat/2013/gmat-idiom ... ed-idioms/
Here's the question again:
While it costs about the same to run nuclear plants as other types of power plants, it is the fixed costs that stem from building nuclear plants that makes it more expensive for them to generate electricity.
A. While it costs about the same to run nuclear plants as other types of power plants, it is the fixed costs that stem from building nuclear plants that makes it more expensive for them to generate electricity.

The comparison in the first half is fine, but in the second half, we have the unnecessary emphatic construction. This is incorrect.
B While the cost of running nuclear plants is about the same as for other types of power plants, the fixed costs that stem from building nuclear plants make the electricity they generate more expensive.
Correct.
C. Even though it costs about the same to run nuclear plants as for other types of power plants, it is the fixed costs that stem from building nuclear plants that makes the electricity they generate more expensive.
The comparison at the beginning is funky .....we could have
(1) it costs about the same to run nuclear plants as other types of power plants
or
(2) the cost of running nuclear plants is about the same as for other types of power plants
but combining these two correct versions, putting the "for" in with the verb "to run," is redundant. This also has the unnecessary emphatic construction in the second half. This is incorrect.
D. It costs about the same to run nuclear plants as for other types of power plants, whereas the electricity they generate is more expensive, stemming from the fixed costs of building nuclear plants.
Second half, beginning with "stemming," is a dangling modifier. This is incorrect.
E. The cost of running nuclear plants is about the same as other types of power plants, but the electricity they generate is made more expensive because of the fixed costs stemming from building nuclear plants.
We meed the "for" in the comparison in the first part, and "is made more expensive" is awkward because it is excessively wordy. This is incorrect.

Does all this make sense?
Mike :-)

One more imp learning from this SC:

A costs the same as B- sub to sub comparison
The costs of running A is same for B---Obj to Obj comparison need Preposition
{Got this rule from Magoosh video so can rely on it :wave }

Analysis based on above rules:
A. While it costs about the same to run nuclear plants as other types of power plants, it is the fixed costs that stem from building nuclear plants that makes it more expensive for them to generate electricity.->correct

Use of "makes " is wrong, Also "It is" in second clause is not needed [/color]

B While the cost of running nuclear plants is about the same as for other types of power plants, the fixed costs that stem from building nuclear plants make the electricity they generate more expensive.->Correct

C. Even though it costs about the same to run nuclear plants as for other types of power plants, it is the fixed costs that stem from building nuclear plants that makes the electricity they generate more expensive.-> wrong we don't need prep here

D. It costs about the same to run nuclear plants as for other types of power plants, whereas the electricity they generate is more expensive, stemming from the fixed costs of building nuclear plants.--> wrong same as C

E. The cost of running nuclear plants is about the same as other types of power plants, but the electricity they generate is made more expensive because of the fixed costs stemming from building nuclear plants.----> wrong Need a preposition

There are two distinct splits here, as you may see; one is the comparison of the costs to run a nuclear plant with just the other types of plants and not their running costs. The second split is the ambiguity of the pronouns, precisely the –third - it in the original. Of course the other two it pronouns may be argued as passable as place holders.

A. While it costs about the same to run nuclear plants as other types of power plants, it is the fixed costs that stem from building nuclear plants that makes it more expensive for them to generate electricity. ----- 1.faulty comparison; cost of running compared with other types of power plants 2. The third pronoun it is dangling without an antecedent. Makes what more expensive? Makes electricity more expensive to generate electricity 3. Costs that makes … A SV mismatch


B While the cost of running nuclear plants is about the same as for other types of power plants, the fixed costs that stem from building nuclear plants make the electricity they generate more expensive.
The comparison, the pronoun problem and the SV mismatch nicely fixed. Correct choice.

C. Even though it costs about the same to run nuclear plants as for other types of power plants, it is the fixed costs that stem from building nuclear plants that makes the electricity they generate more expensive. -----Though the comparison problems are fixed, costs and that makes is S-V mismatch.

D. It costs about the same to run nuclear plants as for other types of power plants, whereas the electricity they generate is more expensive, stemming from the fixed costs of building nuclear plants.
Pronoun they is rather ambiguous; they may refer to either the nuclear or other types.

E. The cost of running nuclear plants is about the same as other types of power plants, but the electricity they generate is made more expensive because of the fixed costs stemming from building nuclear plants. -------- Faulty comparison

Daagh,

Can you please clarify this -

'doesn't B change the meaning? B talks about the electricity becoming more expensive but the original sentence talks about it becoming more expensive for the plant to generate electricity. These are two different things'

Hi,
Can someone please clarify my doubt.
How ellipsis is playing its part over here. I understand that we either needs to use verb (in case of Subject to Subject comparison so that the comparison is not ambiguous) or apply preposition so as to make Object - Object comparison.

Here Object of preposition is {running nuclear plants} and {other types of power plants} -> how they both are logically parallel?
Request you to provide insights.

Thanks

When expanded in full (with ellipsis in brackets), B will be
B While the cost of running nuclear plants is about the same as for (the cost of running) other types of power plants, the fixed costs that stem from building nuclear plants make the electricity they generate more expensive.
The comparison is still between the costs of running one type with the costs for running other types. The only difference is that in the first case we are using ‘of’ as the preposition while in the second arm, we are using ‘for’. As long as we use a preposition for another acceptable preposition, the comparison can be considered be logical and parallel, IMO.

As far as B changing the meaning from the original, I feel the meaning is flawed. There is no way we can ascertain what the “it” stands for. The term ‘it’ does not convey clearly and logically the intended meaning. Hence we have to amend it. B is logical.

Yes, I do understand that Choice B is best amongst all, and this is what I have mentioned above as well.
But, I also acknowledge the fact that there is always something to learn from every correct official answer, and that learning should be carried forward. That is the only way to improve.


sdas wrote:
You see, leaving apart too many rules, we need to chose the answer which is best out of the given options. All other choices except for B, in the question above, have noticeable grammar issues. Quite unlike, Choice B, only uses an additional preposition, which if you notice, most other choices uses as well, so...we choose an option which overcomes other more critical grammar issues (the logical comparison and SV error)

I tried to understand this concept by taking clues from MGMAT, but failed to do so. I would appreciate if someone can help me out.

Here is an example from MGMAT-
The incidence of the disease among men exceeds the incidence among women.
The incidence of the disease among men exceeds that among women.
Here, that is referring to incidence, per explanantion from MGMAT.

So, ellipsis should be -
The incidence of the disease among men exceeds that(of the disease) among women.
Now, going by same concept -

The cost of running nuclear plants is same as that for electric plants.
In the below sentence, what THAT is referring to . Is it "the cost" or "the cost of running".

If it is later, then why do we require an extra preposition?

The cost of running nuclear plants is same as {the cost of running }for electric plants.

Appreciate your help
Thanks

Very interesting question Himanshu.
When you are dealing with ellipsis, it always helps to begin from the completely expanded version with all the words and then move your way to the abbreviated version by applying ellipsis along the way. I will do the same here:

Let's consider only the pertinent portion of the sentence.

1. The cost of running nuclear plants is about the same as the cost of running other types of power plants.
No issues here with the comparison. Both sides of the comparison are grammatically and logically parallel.

Now what if I replace "the cost of running" with "that". After it is obvious that we are comparing cost of running of the two categories of plants. But when I apply this ellipsis, I need something to connect "that" with "other types of power plants".

2. (Without connection with that)
The cost of running nuclear plants is about the same as that other types of power plants. WRONG

2. (with correct connection)
The cost of running nuclear plants is about the same as that for other types of power plants.
So this is where the preposition "for" comes from.

Now we continue with our ellipsis. We can indeed even omit "that" from here since this omission will not lead to any ambiguity.

3. The cost of running nuclear plants is about the same as for other types of power plants.

So this is how I get to the correct sentence containing "for".

Now let's apply the same on the set of sentences:
1. The incidence of the disease among men exceeds the incidence of the disease among women.
1 to 2 - The incidence of the disease among men exceeds the incidence of the disease among women.
2. The incidence of the disease among men exceeds the incidence among women.
2 to 3 - The incidence of the disease among men exceeds the incidence among women.
3. The incidence of the disease among men exceeds that among women.


Image

So the key thing here is that as you replace or omit words, think about what connections you may need to get the correct sentence. The nature of the two sentences is different. In the Official sentence, the main component - cost of running - took direct object without the need of any preposition. So when we replaced this with "that" we needed a connection - i.e. a preposition. However, in the other example, the main component - incidence of the disease - itself needed a preposition to connect to the object and hence when we replaced it with "that" we did not need to get another preposition.

Thus when you cross-check your work in ellipsis, start from the complete sentence and then work your way to simplified version with replacement words and omitted words.

Hope this helps.

Regards,

Payal

Thanks Payal for providing great insights.Kudos to you and your team.

So, preposition can be used in following two ways
1) For removing the ambiguity in the sentence, whether we are comparing subject or object.
e.g John is more interested in video games than {in} his girlfriend. Here, we are comparing objects of prepositions, and we need preposition to clarify the meaning else it will result in ambiguity.
2) The usage of prepositions is as mentioned by you. It could work as a connector with the ellipsis element(that).


2 to 3 - The incidence of the disease among men exceeds the incidence among women.
3. The incidence of the disease among men exceeds that among women.


One question - Can we clear off "that" in the final sentence.
i.e The incidence of the disease among men exceeds among women.

I believe, had the sentence been The incidence of the disease among men exceeds women., then the sentence would have been ambiguous, because then the comparison could be b/w the incidence vs women or men or women.

2. (with correct connection)
The cost of running nuclear plants is about the same as that for other types of power plants.
So this is where the preposition "for" comes from.

Now we continue with our ellipsis. We can indeed even omit "that" from here since this omission will not lead to any ambiguity.

3. The cost of running nuclear plants is about the same as for other types of power plants.

So this is how I get to the correct sentence containing "for".

Now let's apply the same on the set of sentences:
1. The incidence of the disease among men exceeds the incidence of the disease among women.
1 to 2 - The incidence of the disease among men exceeds the incidence of the disease among women.
2. The incidence of the disease among men exceeds the incidence among women.
2 to 3 - The incidence of the disease among men exceeds the incidence among women.
3. The incidence of the disease among men exceeds that among women.

So the key thing here is that as you replace or omit words, think about what connections you may need to get the correct sentence. The nature of the two sentences is different. In the Official sentence, the main component - cost of running - took direct object without the need of any preposition. So when we replaced this with "that" we needed a connection - i.e. a preposition. However, in the other example, the main component - incidence of the disease - itself needed a preposition to connect to the object and hence when we replaced it with "that" we did not need to get another preposition.

Thus when you cross-check your work in ellipsis, start from the complete sentence and then work your way to simplified version with replacement words and omitted words.

Hope this helps.

You are absolutely correct in your understanding. And you are dead on about the ambiguity in the sentence if we omit "that among".

Now you asked about the following sentence - i.e. if we only omitted that and retained among.

The incidence of the disease among men exceeds among women.
IMO, this sentence is also ambiguous since it somehow may consider "incidence of that disease among men" as one entity and when this entity is put together with "among women", it would not make sense.

Let's take another example:
Attraction of child to chocolates exceeds to ice cream. - IMO incorrect
Attraction of child to chocolates exceeds that to ice cream. - Surely Correct.

I hope this helps.

Payal

TO EGMAT

A says:While it costs about the same to run nuclear plants as other types of power plants, it is the fixed costs that stem from building nuclear plants that makes it more expensive for them to generate electricity.


though i had eliminated A but i want to know if the initial comparison in A is faulty ?

if i say : nuclear power plants cost twice as much to run as other power plants . i know that this comparison is oki even without the helping verb "do" because there is no ambiguity

so i get a feeling that in A this initial comparison :While it costs about the same to run nuclear plants as other types of power plants seems to be right comparison wise .it might be wrong because of usage of "it" or because of some redundancy but comparison wise it seems oki .
any thought



Sorry about the delay. I was been busy with some schedule driven activities :) I am pasting my response here: Hope this helps.
I took your sentence sets and applied my method of ellipsis to figure out if the ellipsis results in clear sentence or not.

Your Sentence Set 1
• Nuclear power plants cost twice as much to run as other power plants cost.
o Nuclear power plants cost twice as much to run as other power plants do.
o Nuclear power plants cost twice as much to run as other power plants.

Your Sentence Set 2
• It costs about the same to run nuclear plants as other types of power plants
o It costs about the same to run nuclear plants as it does to run other types of power plants
o It costs about the same to run nuclear plants as other types of power plants.
 Here IMO the meaning is distorted a bit. One may construe this sentence to state the following non-sensical meaning - running “nuclear plants” in the role of “other types of power plants”.
 This is the reason why I believe the ellipsis cannot be applied in the manner we can in the previous set of sentence.

Notice another thing – in the first set of sentences we have “as much as” comparison marker. Whereas in the second set of sentences, we only have “as” marker and hence this can be construed to mean “function” instead of “comparison”.

Pardon my hurried response.

hi folks,

regarding the solution of this question OG13 SAYS :
The emphatic construction "It is X that does Y"(as in the phrase it is Jane who knows answer)should be used only when there is a compelling reason to emphasize the doer of the action.IN this sentence ,emphatic construction is used without good reason.


i am unable to understand what does this mean and request all experts to share their views on this with examples.

regards

Yeah i agree with you its bit convoluted...

let me try anyway..

"While the cost of running nuclear plants is about the same as for other types of power plants, the fixed costs that stem from building nuclear plants make the electricity they generate more expensive.

so costs is MAKING electricity expensive....
while THEY is refering to nuclear plants.
if the intention was to say that fixed costs generate electricity then both verbs would have been connected by AND..(sorry this is just my opinion....i cant frame GMAC like choices) :)
LIKE THIS: ......GENERATE..AND MAKE.....
so THEY is refering to NUCLEAR PLANTS....
hope it helps :)

Dear blueseas
The emphatic structure "it is the fixed costs that ..." would be most appropriate if there were several cost sources under consideration, perhaps one that most people commonly thought was the most expensive, and the sentence were saying: no, contrary to what you expect, the fixed building costs are the most expensive, etc. In this sentence, we have emphatic structure, and it's not particularly clear what contrast we are trying to make. If we emphasize one thing, it should be clear --- this thing is being picked out, highlighted, from what other thing or from among what other things.

You will find a few more examples here:

I hope this helps.

Thanks blueseas for your reply.

I understand what you're saying but somewhere I am still not 100% convinced that "they" is not ambiguous. :(

I just have a feeling that this is a very fundamental and an important concept.

I wish it were - "make the electricity nuclear plants generate more expensive"

"Pronoun Ambiguity" is the most scariest topic to me at this point of my preparation.

Experts... please help me!! :cry:

I was asked to chime in about this question, so let me say the blueseas has this pretty well down. There is no ambiguity in the pronoun in (B) because the structure of the first half of the sentence; "While the cost of running nuclear power plants..." sets up a clear comparison between nuclear and non-nuclear power plants, meaning the context makes it absolutely unambiguous what "they" refers to. Remember, the GMAT sentence correction section is designed to test logical reasoning, not just rote mechanics. Even if in some theoretical grammatical sense the word "they" could conceivably refer to fixed costs, no fluent speaker would reasonably be confused by the sentence at all.

Hope this helps!

in B, we see "as for" . This is "conjuction+preposition". whenever we see this pattern, be careful of ellipsis. the process of "making full" this pattern is not easy . we need to practice and focus on this pattern.

this pattern and ellipsis is tested many times on og books and gmatprep. we can see this testing if we pay attention.
