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.

• 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.

• 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 Payal,
Request you to please validate my reasoning for the above sentence. I believe, the sentence is ambiguous because we can infer two VALID meanings

It costs about the same to run nuclear plants as other types of power plants.

Meaning 1 -when we can assume infinitive -> "to run" as Common
It costs about the same to run nuclear plants as {to run} other types of power plants.

Here, Meaning comes out to be that Cost of Running Nuclear plants is same as Cost of running other types of power plants. This is logically parallel

Meaning 2-

It costs about the same to run nuclear plants as other types of power plants{costs}.

Here, we can infer that cost of running nuclear plants is same as cost of other types of power plants i.e we are not comparing cost of running plants but comparing cost of running one type of plant with some other costs of other types of power plants, the costs could be build costs, maintenance costs etc. This is Unparallel

Doubt -
As per parallelism rules, both sides of comparison must be logically parallel. Now, my doubt is can we say that the above sentence is ambiguous because it is conveying two meanings i.e we are not sure what author is trying to compare and our job is to make it logically correct. Correct?

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Going by the above concept, Can you please validate my reasoning for the below sentence as well, its taken from OG, though the original sentence may be incorrect for other reasons.

Authoritative parents are more likely to have children than permissive parents

Meaning 1

Authoritative parents are more likely to have children than {are}permissive parents
It can be inferred that comparison is between two types of parents. i.e Authoritative parents have greater chances of children than permissive parents.

Meaning 2
Authoritative parents are more likely to have children than {to have}permissive parents
Now, sentence is comparing the two types of generations. i.e Authoritative parents may have greater possibility of having children(upcoming generation) than having permissive parents(previous generation). Is it illogical meaning? Please put your thoughts across

All, I am trying to understand is that sentence can have two types of ellipsis present. One is with Verb of Subject and another is with Infinitive+direct object. Now, when such is the case can we negate a choice when sentence have this type of ellipsis present even if one Meaning is purely justified and another one is not.

Thanks
Himanshu

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.

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.....

i think if i change "costs" to "cost" in option c it can be considered an asnwer for this question. Please correct me if i am wrong.
c.Even though it cost 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.

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.

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.

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!

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.

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..

Bump on this question.

Many people have chimed in on aspects of the question/answers and, moreover, a few tangents have been well developed.

But can someone (preferably an expert ) break down exactly what is wrong with each of the wrong answers here. There is so much going on and I'm still confused.

-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 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.

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

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.

Well said, vietmoi999!!

As we all know, the GMAT loves Parallelism, and one of the hardest issues about parallelism are the common words what one can drop instead of repeating. See this post:
http://magoosh.com/gmat/2013/dropping-c ... -the-gmat/
Yes, as vietmoi999 said, this is a crucially important GMAT SC issue on which to focus.

For option (C), look at my post from February 3, 2014, immediately above your post. Let me know if anything there is not clear.

For emphatic construction, see this post:

Hi Payal,

I have a question regarding 3rd statement.

If your 3rd statement changed to below by inserting 'OF' after that then it would be right?
The incidence of the disease among men exceeds that of among women.

Regards,
Chetan

I believe "that" would automatically refer to "incidence of disease" (and not just "incidence"); so we don't need "that of".

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.
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.

I think " as for other types of plants" is correct in B,C and D. but I do not know why.

pls, help. what is the full version of comparision in choice B,C and D.
the full versions are
cost of running nuclear plant are about the same as the cost for other types of power plants.
it costs about the same (expenditure) to run nuclear plant as the expenditure for other types of power plants.

I do not see the parallelism in comparision. this non-parallelism are not prefered certainly but it can still appear in OA if there is no choice better.

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.

Hi Payal,

The incidence of the disease among men exceeds that of among women.
Regards, Chetan

Dear Chetan,
We definitely don't need two prepositions in a row.
... that of women. (correct)
... that among women. (correct)
... that of among women. (a disaster)
Does this make sense?

Dear vietmoi999

(B) While the cost of running nuclear plants is about the same as it is for other types of power plants
This is perfectly correct. A perfect comparison. This, of course, is the OA.

(C) Even though it costs about the same to run nuclear plants as for it costs to run other types of power plants
This one has the same structure, but because what comes before is different, the structure is problematic here. The preposition "for" is not needed here. A different set of words would be implied.

(D) It costs about the same to run nuclear plants as for it costs to run other types of power plants
Same problem as (C).

Incidentally, the GMAT loves this trick --- one correct option with (Structure A)(Structure B), and then other incorrect choices with (Structure C)(Structure B), ---- even though (Structure B) would be correct on its own, it works only with (Structure A) and not with (Structure C). They love this pattern.

Does this make sense?
