A. account for the presence of the element iridium (originating deep within the earth), and the presence of quartz having been - Incorrect. Parallelism error.

B. of the element iridium (originating deep within the earth), and of quartz - Correct. would explain the presence of a buried crater, of the element iridium, and of quartz.

C. the element iridium (originating deep within the earth), and explain the presence of quartz having been - Incorrect. would explain the presence of x, y and explain the presence of z is not parallel again.

D. the presence of the element iridium (originating deep within the earth), and explain the presence of quartz - Incorrect. Parallelism error again.

E. explain the element iridium (originating deep within the earth), and the presence of quartz - Incorrect. Parallelism error.

Answer: B

Hello somtsat99,


I am just adding my two cents here. When the elements in a parallel list are big phrases, the scope of possible parallel elements also increase by far.

Let's take a look at the sentence with the correct answer choice B:

Positing an enormous volcanic explosion at the end of the Permian period would explain the presence
    of a buried crater,
    of the element iridium (originating deep within the earth), and
    of quartz shattered by high-impact shock waves.


Since all the three elements are prepositional phrases, they are perfectly parallel.

Since of has been used in all the three elements, another possible parallel list can be what elegantm has stated in his post as Pattern 1.


Hope this helps. :-)
Thanks.
Shraddha

Could someone clarify how D is wrong?

Here is the sentence with D:
Positing an enormous volcanic explosion at the end of the Permian period would explain the presence of a buried crater, the presence of the element iridium (originating deep within the earth), and [would] explain the presence of quartz shattered by high-impact shock waves.

Just before this post, I read:
https://gmatclub.com/forum/your-verbal- ... 46533.html
which suggests not be over fixated with true parallel structure to the hilt.
Shouldn't there be more than just parallelism error for us to eliminate choices?

Hi sevenplusplus, let's look at the sentence with D again:

Positing an enormous volcanic explosion at the end of the Permian period would explain the presence of a buried crater, the presence of the element iridium (originating deep within the earth), and explain the presence of quartz shattered by high-impact shock waves.

By the intended meaning of the sentence, hopefully it's clear would explain is trying to explain three elements. In D, the repetition of the presence in the second element suggests that the way to do (what we call as) XYZ deconstruct is:

Positing an enormous volcanic explosion at the end of the Permian period would explain

i) X: the presence of a buried crater
ii) Y: the presence of the element iridium (originating deep within the earth)
iii) Z: explain the presence of quartz shattered by high-impact shock waves.

Once we have done this deconstruct, the common portion of the sentence (in this case Positing an enormous volcanic explosion at the end of the Permian period would explain) should individually make sense with X, with Y, and with Z.

In D, this common portion is not making sense with Z, because the sentence would read:

Positing an enormous volcanic explosion at the end of the Permian period would explain explain the presence of quartz shattered by high-impact shock waves.

explain explain is clearly incorrect.

p.s. Our book EducationAisle Sentence Correction Nirvana discusses this very powerful method of tackling parallelism (XYZ deconstruct) , its application and examples in significant detail. If someone is interested, PM me your email-id; I can mail the corresponding section.

Thanks for the reply. How do we know that "would explain" is "out" of the XYZ deconstruct? My argument is that it could be considered part of each X, Y, Z.

Sure. So, let's try putting would explain within the XYZ deconstruct.

Positing an enormous volcanic explosion at the end of the Permian period

i) X: would explain the presence of a buried crater
ii) Y: would explain the presence of the element iridium (originating deep within the earth)
iii) Z: would explain explain the presence of quartz shattered by high-impact shock waves.

Again, as is evident, Z (would explain explain the presence...) is incorrect.

A. account for the presence of the element iridium (originating deep within the earth), and the presence of quartz having been - Incorrect. Parallelism error.

B. of the element iridium (originating deep within the earth), and of quartz - Correct. would explain the presence of a buried crater, of the element iridium, and of quartz.

D. the presence of the element iridium (originating deep within the earth), and explain the presence of quartz - Incorrect. Parallelism error again.

E. explain the element iridium (originating deep within the earth), and the presence of quartz - Incorrect. Parallelism error.

Answer: B



Hi Vyshak ,

I have a doubt here. When do we use a comma before 'and'?
Usually its like a,b and c.
In what conditions, do we use- a,b, and c? and what's the difference?

Really appreciate if you or anyone on this forum can explain.

Regards,
ashygoyal
