1] so the statement says "adhere to one another" --> means they stick together

2] later the statement says that even though they are together they do "exclusive" things

3] so we are looking for something which which says that first part and the second part are contradictory to each other.

(A) beating in unison and adopting -- > it is linking the 1st and 2nd part together using "and"
(B) they beat in unison while adopting -- > doesnt make 1 and 2 opposite of each other.
(C) beat in unison, and adopt -- > same , makes 1st and 2nd part erelate to each other.
(D) beating in unison yet adopting -- > yet makes the 1st and 2nd part oppose each other
(E) even though they beat in unison and adopt -- > again , has a "and" which makes 1 and 2 relate to each other.

(D) is my choice

We can separate out A and D as we need -ing word after the comma (To show extended meaning of the clause before)

D for me. C looks tempting but "exclusive of one another" indicates that there should be a "yet", or "but" or something like that.

I just joined this community and by far the best resource I've ever seen for gmat.

So....

A peculiar feature of the embryonic mammalian circulatory system is that in the area of the heart the cells adhere to one another, beating in unison and adopting specialized orientations exclusive of one another.

Here, the underlined portion seems to act as an adjective clause modifying "the area of the heart." [read it as one clause before the comma and you'll see.] Without a comma between "heart" and "cells," the sentence lacks a clear subject after "another,"..So, my answer was B since it was the only one with a clear subject even though "they" is not referenced the best way, but it's better than the other choices.

The answer D makes sense to me if the question was:
A peculiar feature of the embryonic mammalian circulatory system is that in the area of the heart, the cells adhere to one another, beating in unison and adopting specialized orientations exclusive of one another.

Now there is a clear subject and D makes the most sense.

I hope I didn't add to the confusion here.

While I agree that D seems to be the most accurate answer, I think this sentence needs a comma after the word 'heart' to read: "A peculiar feature of the embryonic mammalian circulatory system is that in the area of the heart, the cells adhere to one another,..........

Otherwise, one could easily misconstrue the part of the sentence that reads "in the area of the heart the cells adhere to one another" to be a description of an area of the heart where cells adhere to one another, giving the sentence a whole new meaning and possibly "B" as its answer.

Any thoughts anyone?

Here's my take on this question w/out repeating too much of what other people's said.

Since the last part of the sentence said, "beating in unison and adopting specialized orientations exclusive of one another.", we should see a contrasting triggering word to differentiate between "unison" and "exclusive of one another". Answer choices A, C, and E all used "and", for which it doesn't trigger the contrasting effect. Only B and D uses the right words - while (B) and yet (D).

Looking into B and D, B creates a common splice. In (B), "they beat in unison..." creates a complete sentence with a subject and a verb. In conjunction with the non-underlined sentence, the comma in between the two creates the grammatical error; therefore, (B) is incorrect. (D) fixes all the problems of this sentence.

In response to MrEasy's question with the comma after the word 'heart', I don't believe the comma is necessary since the material after the word 'heart' is a necessary clause, which requires no comma in between the two clauses. I hope I didn't confuse anyone with what I said. Also, just to go aside from that, people get bogged down by parts that are not underlined way too much; everyone should take what's given to them (the non-underlined portion) knowing that it's correct and don't question the non-underlined portion. I just wanted to point that side point out, though I'm pretty sure most people on this forum already knew that.

A very tricky one!

If there were another answer choice that read: "beat in unison, yet adopt", would it be more preferrable to the OA?

Thanks.

Hey All,

Everybody seems to have the right answer, but just to make it clear, adding a comma would NOT improve this sentence. Answer choice C is hoping to get you with a kind of shallow parallelism. We want to differentiate between the main verb "adhere", and the two subordinate verbs. To make this all one list changes the meaning for the worse.

Hope that helps!

I had a feeling that with progressive form of verb i.e)adopting and beating you can use 'of'....

beating in unison and adopting specialized orientations exclusive of one another.

If it was exclusive to one another then we could have used 'beat in unison and adopt' i.e C.

I chose D for that reason. Any comments?

Hi all,
i have understood the statement as :-

A peculiar featureof the embryonic mammalian circulatory system is that in the area of the heart the cells adhere to one another ...

The peculiar feature is that the cells adhere to each other.

If viewed from this angle, wouldn't option E make some sense?
Since it does introduce the contradiction with "Even though" and also maintains the parallelism with "adhere" by using "beat" and "adopt".

E : A peculiar feature ..............is that ..................the cells adhere to one another, even though they beat in unison and adopt specialized orientations exclusive of one another.

the placement of even though in latter half : seems the Contrast is bxn = 1. Adhere together , 2. Beat together & Adopt specialised orientations : Adhere together & beat together = where is the contrast, Guess they don't bring out the intended contrast correctly.

The intended contrast : Between = 1. Beat together, 2. Adopt individual /specific orientations ie Some GROUP ACTIVITY .....AND.... Some SOLO ACTIVITY
UNISON..............................YET(implies contrast).......................SPECIALIZED orientations

Leading to E = My understanding

A peculiar feature of the embryonic mammalian circulatory system is that in the area of the heart the cells adhere to one another, beating in unison and adopting specialized orientations exclusive of one another.
(A) beating in unison and adopting
(B) they beat in unison while adopting
(C) beat in unison, and adopt
(D) beating in unison yet adopting
(E) even though they beat in unison and adopte

There are two clauses in the question. The subject of the first clause is ...Singular . The subject of the second clause is also the same. Now as the subject is singular, there must be a singular antecedent in second clause. On the basis of this we can eliminate options B & E as these options have "they" referring to "A peculiar feature... .circulatory system".
Now we are left with options A, C & D.
According to the meaning of the statement the "A peculiar feature " must represent a single feature but in the option A "beating in unison and adopting specialized orientations " are two features. Apart from that there must be some contrast to so the peculiarity of the xyz system. A contrast word will resolve the problem.
So option D is the correct answer.
