[syxphoebe]

A recent United States Census Bureau report shows that there are more than three times as many households where the children and grandchildren are living in their grandparents' home as compared to households where the grandparents are living in their children's or grandchildren's
home.
(A) as compared to households where the
(B) as there are households where the
(C) as those whose
(D) than compared to those where the
(E) than there are whose

answer：B

"there are...as many households where...as there are households where..."
i think the structure is bad.
the second "there are" should be omitted.

A/C？ THXO(∩_∩)O~

as we wrote about here:

--

first off, you underlined the wrong part of the sentence.

--

DO NOT QUESTION OFFICIALLY CORRECT ANSWERS.
CORRECT ANSWERS ARE CORRECT.

questioning them is a complete and total waste of your time, since they are correct, and are accepted as such by the official authors of the test.

all you can do is learn from them, so, that is the correct attitude. take each correct answer and learn all that you can from it.

--

you are not incorrect, by the way, about omitting "there are"; you would indeed get a grammatically correct sentence that way.

the problem, though, is that the resulting sentence would be extremely awkward and difficult to read.
try it yourself: copy and paste the sentence, and replace the (supposed-to-be-)underlined section with just "as households where the".
see if you can read through it just once and get an accurate idea of its meaning; i bet you won't be able to. it will probably take 2-3 reads, at bare minimum.

luckily, the gmat doesn't (and won't) make you choose between two legitimate writings of the sentence based only on something like "more difficult to read vs. less difficult to read".

sorry ~ i have corrected the wrong sentence.

thx~

i pay more attention on details.i just want to know"why this choice is wrong? why that is right?..." so,sometimes,i'm confused.maybe i neglect sth that is important in sc.i use the wrong method to prepare sc.

thank you again.i need some time to digest your reply.

Hey, syx - it's great to ask questions to make sure you understand why. Keep it up!

[ashish.jere]

ron,

can you please explain the problem with (A)?

One reason what I can see is that the original sentence wants indicate a difference, rather than a similarity. Hence 'compared to' is not ok here. Please validate.

@Ashish..
Could this be because of redundancy?
as many households...as already indicates comparision so using "compared to" again I guess is unnecessary. I might be wrong though..

A - should be "as many x as y." the "as compared to" is long winded. A also is not parallel and missing a "there"

[hberens18]

Can someone explain what is incorrect about C?
C) as those whose

A report shows that there are more than three times as many X and as Y
X = Households where...
Y = [Those = households] whose.....

This is the classical comparison issue.

A recent United States Census Bureau report shows that there are more than three times as many households where the children and grandchildren are living in their grandparents' home as compared to households where the grandparents are living in their children's or grandchildren's
home.
(A) as compared to households where the
(B) as there are households where the
(C) as those whose
(D) than compared to those where the
(E) than there are whose

idioms used to compare here are,
1) more x than y
2) as many x... as y..

as many households where the children and grandchildren are living in their grandparents' home as compared to households where the grandparents are living in their children's or grandchildren's


A - compared to is unnecesary. Coz u know, "compared to" is another idiom for comparison which is useless since there is an idiom as.... as to compare already.

B - Correct.. correctly uses as ... as idiom and compares "households" precisely.

C - House holds are compared to "children and grandchildren"

D,E - than is a wrong idiom for as... than

[supratims]

Here as many as , the idiom is for 'households', and so C is wrong which compares with children and grandchildren

[RonPurewal]

A - should be "as many x as y." the "as compared to" is long winded. A also is not parallel and missing a "there"

yes. extremely well done.

i would NOT try to eliminate based on the distinction between "compared to" and "compared with". i know that some old questions in our cat exams are mildly obsessed with that distinction, but i don't think there is an OFFICIAL basis for it (i.e., a basis in the actual questions provided by GMAC).

for all practical purposes, you should be able to treat "compared to" and "compared with" as the same. if we find any consistent distinction IN OFFICIAL PROBLEMS, i'll be sure to post back on this thread and explain.

if you have "three times as many as...", then you CANNOT include "compared to", because you're then saying the same thing twice. this is REDUNDANCY, and is a fatal error.
same thing as saying "reply back", "increase upward", etc. can't do it.
