'As' has 4 functions

1) comparison
2) simultaneous action
3) reason
4) presenting role/function. Ex - As a brother John takes care of his younger sister. Ex 2 - BB joined Gmatclub as founder.

What is rise/act referring to? I feel it can't refer to a prepositional phrase "of rocks", so I see breakwater as singular..

Going by parallelism is fine, but we need to look at subject verb singular/plural agreement too, right?

as should be followed by a verb and like compares noun,
So shouldn't B be the answer?

The OA according to OG13 is C

Nope. B is not parallel first of all.

In a plan to stop the erosion of East Coast beaches, the Army Corps of Engineers proposed building parallel to shore a breakwater of rocks that would rise six feet above the waterline and act as a buffer, so that it absorbs the energy of crashing waves and protecting the beaches.

(B) act like a buffer so as to absorb
(C) act as a buffer, absorbing

Moreover "as" is used also to compare FUNCTIONS, "like" cannot do that: as-vs-like-correct-and-incorrect-usages-133950.html

These are the subject-verb pairs so in option C the absorbing and Protecting is presenting the result of the clause " act as buffer" Is this correct?

Hi fozzy.

You're not totally correct.

Verb-ing modifier + comma ==> always modifies a preceding clause. "absorbing" || "protecting" are verb-ing modifiers that modify a preceding clause. Let think, what can absorb water? ==> a buffer. What can protect the beaches? ==> a breakwater of rock.

So, the modifier part modifies the preceding clause "a breakwater of rocks that would rise six feet above the waterline and act as a buffer", not only "act as a buffer".

Hope it helps.

I got the correct answer C but I wanted to understand if Ing modifier ( absorbing ) is modifying the preceding clause?

this is how I eliminated the options. Now Rise has to be parallel to Act . So options B and c are the only ones left. Option B has introduced a parallelism error at the end of the sentence because absorbing must be parallel to protecting. Hence option C is the answer. Correct me if my analysis is wrong.

In a plan to stop the erosion of East Coast beaches, the Army Corps of Engineers proposed building parallel to shore a breakwater of rocks that would rise six feet above the waterline and act as a buffer, so that it absorbs the energy of crashing waves and protecting the beaches.

(A) act as a buffer, so that it absorbs
(B) act like a buffer so as to absorb
(C) act as a buffer, absorbing
(D) acting as a buffer, absorbing
(E) acting like a buffer, absorb


I got confused between A and C, though I selected C finally but I still have a doubt.

I am under the assumption that in C, the ',absorbing' should modify the Army Corps. If the comma were not there before 'absorbing' then the it would have modified 'buffer'. Kindly clarify.

Comma+verb-ing modifier modifies preceding clause immediately before it. here- act as buffer

Thanks for the reply SWAT09.
But then 'act as buffer' is not doing the action of 'absorbing'. It is the 'buffer' that is doing the action, so ideally there should be no comma.

Please clarify.

(A) act as a buffer, so that it absorbs
(B) act like a buffer so as to absorb
(C) act as a buffer, absorbing
(D) acting as a buffer, absorbing
(E) acting like a buffer, absorb


breakwater of rocks stated in the stem suggests that it will play the role of a buffer. Hence 'as' rounds up doing that much better than like. Also we need to make something after comma in parallel to protecting. Hence only a -ing participle phrase will work here.

So seeing the answer choices on the above -

(A) act as a buffer, so that it absorbs

Explanation - absorbs is removing parallelism. Hence incorrect

(B) act like a buffer so as to absorb

Explanation - absorb is removing parallelism. Hence incorrect

(C) act as a buffer, absorbing

Explanation - uses 'as' correctly. Also maintains parallelism by using -ing form of absorb. Hence Correct.

(D) acting as a buffer, absorbing

Explanation - 'acting' is disrupting parallelism with 'rise'. Hence incorrect.

(E) acting like a buffer, absorb

Explanation - absorb is removing parallelism. Hence incorrect

Hence C

Please clarify.

ShashwatPrakash the intention here is " absorbing the energy of crashing waves and protecting the beaches" is the result of an activity = a breakwater of rocks that would rise six feet above the waterline and act as a buffer. The whole activity of - a breakwater of rocks rising six feet above the waterline and acting as a buffer is doing the action of absorbing and protecting. Its like cause and effect.

if it was ..act as buffer absorbing the energy..... then "absorbing" here will only modify concrete subject "buffer" but then doing so will not present a cause and effect situation.
