Hi,

I am stuck with D and E.

Do we have to eliminate D for using "untill" ?

You could have eliminated (D) for its faulty modification, as aragonn nicely demonstrates. But the usage of "until" is also a problem. When the word follows an action, the implication is that the action has ceased. For example, "Amy yelled at her dog until it stopped eating her father's heart medication." This sentence conveys that Amy stopped yelling once her dog stopped eating her dad's pills.

In (D) we have "mountain yellow-legged frogs of the Sierra Nevada take three to four years until they reach adulthood." So once the frogs reached adulthood, they stopped taking three to four years? That's nonsense - another reason to give (D) the boot.

I hope that helps!

csaluja - if this helps.

On the GMAT, COMMA + VERBed -- or COMMA + adverb + VERBed -- generally serves to modify the immediately preceding noun or noun phrase.
In D, COMMA + thus restricted seems to refer to adulthood (the immediately preceding noun), implying that ADULTHOOD is thus restricted to deeper bodies of water.
Not the intended meaning.
Eliminate D.

+1 for E.

(A) it takes three to four years for the mountain yellow-legged frog of the Sierra Nevada to reach adulthood, and so they are

(B) it takes the mountain yellow-legged frog of the Sierra Nevada three to four years until it reaches adulthood, and therefore it is

(C) in the Sierra Nevada, mountain yellow-legged tree frogs take three to four years to reach adulthood, thus being

(D) mountain yellow-legged frogs of the Sierra Nevada take three to four years until they reach adulthood, thus

(E) mountain yellow-legged frogs of the Sierra Nevada take three to four years to reach adulthood, with the result that they are --> Correct, maintains parallelism, and conveys the intended meaning

Hence, E.

As we have frogs after Unlike, we need to maintain consistency and have any other animal or different frogs. This disrupts the consistency. Hence Incorrect.

Maintains consistency. Frogs compared to different kind of Frogs. But 'Take .... Until' is wrong idiomatic usage. Hence Incorrect

Maintains consistency. Frogs compared to different kind of Frogs. Also idiomatic usage corrected here. Best possible answer

For D, “thus restricted” doesn’t flow right to me.

Would need a “are” in there somewhere to make it work

D would have been had it been written as -

Please correct me If I am wrong.

Well Rahul, according to your version, which is restricting whom in your edited version?
As such your sentence means that:

mountain yellow-legged frogs of the Sierra Nevada take three to four years until they reach adulthood, thus(mountain yellow-legged frogs) restricting mountain yellow-legged frogs to deeper bodies of water that do not dry up in summer or freeze solid in winter.

Isn't the meaning skewed here?

Hi GMATNinja,

I was wondering could you please explain the difference between option D and E? Can we eliminate option D solely on the basis of incorrect idiomatic use "take...until" or are there any other errors with option D?

Hi,

I am stuck with D and E.

Do we have to eliminate D for using "untill" ?

A and B are wrong since they compare ‘frogs that ….’ To a time period. C is wrong because it is improperly constructed and implies that the mountain yellow-legged frog takes three-four years to reach adulthood specifically in the Sierra Nevevada. Also there is no need for ‘the’ before Sierra Nevada. D has an error in the use of ‘until’. That implies that once the frogs reach adulthood, it no longer takes three-four years for this species to reach adulthood. This obviously makes no sense.



E is the right answer.
