(A) due to their enhancement of reproduction or survival, but that they are
(B) due to the reproduction or survival they enhance, but they are
(C) because they enhance reproduction or survival, but
(D) because they enhance reproduction or survival, but are
(E) because of enhancing reproduction or survival, but are

I am between D and E. For me, D looks better, but I cannot explain it.

Can somebody explain it? OA?

this ones been discussed a few times on here, and it boils down to C or D. Honestly, I went with D because it has the right idiom (not X but Y), and also maintains parallelism 'are ... are'

..many biological traits are not ... but are...
Left with D and E.
even though I find use of 'they' bit confusing in D but E is even worse. So, reluctantly, D.

B due to the reproduction or survival they enhance, but they are
C because they enhance reproduction or survival, but
D because they enhance reproduction or survival, but are
E because of enhancing reproduction or survival, but are

Eliminate A and B. Reason : Due to means caused by
Eliminate C . Reason : Try substituting it in the original sentence.
E is wrong because first ing is wordy. Also, if you observe closely, it modifies the original menaning.

I am also looking for a thorough reasoning of D? I dont know why "are" at the final of D is neccesary?

D for me too. Sondenso, a humble request to you. mate. Please do not delay posting teh OA as most of us are losing our hair waiting for you to post it. You know, it is really hard to wait once we made that selection. Having been a part of the genration that believes in instant gratification, I can't help but expect a quicker affirmation here. Can you help?

D for me too.

another humble request for Sodenso,

please put GMATPrep in the subject line if its a GMATPrep question. I realise you want healthy discussion of these questions, but I am sure you do not want to dilute your fellow clubber's gmatprep experience. Also most, if not all, GMATPrep questions are discussed several times over in this forum. A search would yield good hits if you were to look for explanations.

Kudos for being so enthusiastic however.

ok I will give it a shot at explaining.

According to the parallelism rule, yes the [are] is optional, BUT, sometimes it necessary.

This is one example where its necessary since there is a modifier that clouds the parallelism. Meaning the ", but simply random byproducts..." could be confused as a sub modifier of "survival" or the first modifying phrase.

So ", but are..." construction, removes this confusion by realining the focus of the sentence to the original stem of the sentence. i.e "... are not the products of natural selection, <modifier>, but are ..."

Let see the rule of parallelism: not X, but Y. So the sentence should be: not ARE X, but ARE Y.

The original violates that rule and say "are not X, but are Y" So confusing! Do you think so?

You are missing verb - are - in C. D corrects this problem.

Difference between C and D

Idiomatic usage is Not X but Y
Here if it was mentioned not products of natural selection without the "the" C would have been ok. The extra "the" in front of products needs "are" to maintain parallel structure

D is not parallel.

The idiom is not X but Y.
In D X is a noun and in Y it is a verb.

Whats wrong in C??

I found some discussion on other forum. Should help everyone:

there are two ways of reading the sentence if choice C is inserted. here they are, with the boldface in each indicating exactly what is construed as a modifier:

1) Paleontologist Stephen Jay Gould has argued that many biological traits are not the products of natural selection, favored because they enhance reproduction or survival, but simply random by-products of other evolutionary developments.

2) Paleontologist Stephen Jay Gould has argued that many biological traits are not the products of natural selection, favored because they enhance reproduction or survival, but simply random by-products of other evolutionary developments.

The first example can be read as:

Paleontologist Stephen Jay Gould has argued that many bio traits are not X [the products...selection], modifier of X [favored...survival], but simply Y [random...developments].

So, above, I'm contrasting X and Y, and X also happens to have a little extra modifier going on.

The second example can be read as:

Paleontologist Stephen Jay Gould has argued that many bio traits are not X [the products...selection], modifier of X [favored...survival], modifer of modifier of X [but simply...developments].

In other words, I'm no longer contrasting X and Y - instead, I'm saying something about X and then giving a couple of modifiers in a row to describe it - there is no longer a comparable, contrasting Y. (And this doesn't make logical sense if you know anything about the topic. But it is a grammatical possibility - someone who didn't know that this is illogical couldn't be sure that this isn't the meaning.)

I need that "are" in there to know that it is definitely option 1: comparing X to Y. Biological traits are not X but are Y.

Not X but Y. How can X be a noun and Y a verb?

This is irritating. I went for C lured by the II ism not X but Y . And then this new form of IIism pops in with Are in between. Im going insane.
