GMATNinja GMATNinjaTwo Could you help to explain the different of "to hold" (A) and "for holding" (B) in this problem?


Ziyuen, I don't think it's a major issue here. That particular part of the sentence describes the usefulness of the deep-rooted vegetation, and I don't think that "for holding" is necessarily wrong in this case. "To hold" is probably a little bit better, since "for holding" seems to imply some sort of specific design or intent -- and that's probably not ideal here. But I wouldn't automatically dismiss "for holding" in this particular sentence.

Not coincidentally, it's a non-issue in the sentence. The GMAT gives us very clear errors (pronouns and redundancies) in the other answer choices -- so there's no real reason to even worry about the idiom. That's classic GMAT SC: distract us with a split that doesn't matter much, while the real issues lie elsewhere. :)




Hi GMATNINJA

Do we have parallelism issue in option B

(B) from the meandering shape typically found in well-vegetated zones to the braided pattern that they find in areas without deep-rooted vegetation for holding


pls help

Geologists have found that streams in the Karoo basin of South Africa changed suddenly at the end of the Permian period 250 million years ago, from the meandering shape typically found in well-vegitated zones to the braided pattern found in areas without deep-rooted vegetation to hold the soil together..

Meaning (removing modifier) : Geologist have found that streams changed to hold soil together.

Am I correct.

Pls. help.

(A) from the meandering shape typically found in well-vegetated zones to the braided pattern found in areas without deep-rooted vegetation to hold
(B) from the meandering shape typically found in well-vegetated zones to the braided pattern that they find in areas without deep-rooted vegetation for holding
(C) from the meandering shape typical in well-vegetated zones to the braided pattern found in areas where it is without deep-rooted vegetation for holding
(D) shifting from the meandering shape typically found in well-vegetated zones to the braided pattern found in areas where it is without deep-rooted vegetation for holding
(E) shifting from the meandering shape that is typical in well-vegetated zones to the braided pattern being found in areas without deep-rooted vegetation to hold


IMO, one does not need to break one's head on doubtful things or unknown things; After all, there is going to be no help in the Hall. Here is yet another quick fix. (This is just a last minute attempt)
For all it matters, either 'for holding' or 'to hold' might be a non-issue as Ninja said, because both express some degree of intent. It is prudent to look for other more 'visible' cracks.
1. The reference for 'they' in choice B is murky; it may refer to geologists, or the streams or an expletive to refer to the people in general. Therefore, B is out.
2. Similarly, 'it' also seems to have no genuine reference. It may refer to pattern or shape, but none is fitting. Therefore, let us dump C and D.
3. It is apparent that 'being found' is wrong in E.
4. Only A is left.

At some desperate point, it might be good enough to take A and get going.
However, my disclaimer is once again that this is only an additional way of cracking the nut. There is nothing as good as knowing the fundamentals thoroughly.

Hi Daagh,

Can you help in narrow down the type of structure followed in Option - A?

Geologists have found that streams in the Karoo basin of South Africa changed suddenly at the end of the Permian period 250 million years ago, from the meandering shape typically found in well-vegitated zones to the braided pattern found in areas without deep-rooted vegetation to hold the soil together.

1. Independent Clause +, Appositive modifier
2. Independent Clause +, Verb-ed modifier
3. Others (which I am missing here)

Thanks
-Ankit

Don't you think

" ---- changed suddenly from the meandering shape typically found in well-vegitated zones to the braided pattern found in areas without deep-rooted vegetation to hold the soil together at the end of the Permian period 250 million years ago, "

would be better than the original? Is it OK to separate them that much?
