A. that might at one time have died as children - relative pronoun is Who
B. who might once have died in childhood
C. that as children might once have died - same as A
D. who in childhood might have at one time died
E. who, when they were children, might at one time have died

D and E suggest the chnage in the meaning of sentence
It says, that people might have died one time in childhood, which is wrong

Hence B

moreover Childhood is parallel to Old age

So B and D remains

B is more clear and consise when compared with D

When answering this question, I came to a point where I couldn't decide between B and D. I suppose picking the shorter between the two could be a good strategy.

I couldn't understand the following explanation from GMAC:

"...Once, not the ambiguous and wordy at one time, is parallel to the adverb now..."

Can someone please explain the parallelism rule used here?

Thanks,

Once can be used in two ways:

1) Once - to signify specific time or one instance

Once (time) there was GMAT.

If we have to specify indefinite time "once" cannot be used.

2) Once - as a conjunction

I would like do OG11 once I am done with OG10.


Now if you look at all the choices again. This becomes very easy.

A - one time [should be "once"]
B - Who + once
C - that ["who" should be used to refer to people not "that"]
D - one time [should be "once"]
E - one time [should be "once"]

Hope this helps.

Yes, but what is the issue with parallelism in the original sentence, with respect to the usage of at one time ?

a question:

D is wrong simply because there is AT ONE TIME instead of ONCE, or also because of the position of the words?

I mean...

D. who in childhood might have ONCE died

would have been correct??

Thanks to the genius who can help!

"Formerly" or "in olden times" is a standard meaning of 'once'. "at one time" is sometimes used to mean the same thing, but I think what the OG is saying is that it isn't as well-established with that meaning, and it's ambiguous because it could mean "simultaneously" or "at a specific moment."

Even if "at one time" were changed to "once" in D, it would still be wrong, because putting the words in that order changes the meaning from what is intended. The sentence is intended to mean "In earlier times, they could have died in childhood." Saying "might once [have died in childhood]" accomplishes this.

If you switch the order of the words around as in D, you get "in childhood might [once have died]" which means something like "In their childhood, there was once a time when they could've died."

the only way after narrowing it down between B and D can be done by ||ism...

because childhood is || to old age...(the reason why B wins)..

died in childhood.....now live into old age........

(in an exam, perhaps there is not so much of time to philosophize between B and D and their literal meanings)..only through || ism can they be correctly narrowed down quickly)

A. that might at one time have died as children
B. who might once have died in childhood
C. that as children might once have died
D. who in childhood might have at one time died
E. who, when they were children, might at one time have died

OA: B

People + That wrong, this eliminates A and C.

Were children + Have died (incorrect tenses together) This eliminates E.

Between B and D, the structure who + verb is better than who+ prep phrase. In general, adverbs of time should go at the end or at the beginning of the sentence. So B is better than D.

OG11 explanation is that " who should be used to refer to people".

I think gmat prefer "who" than "that"

because general grammar said that "that" can be used for persons and things.

is my thinking correct? pls, help.
