A. moving in unison and assuming-contrast is not explicitly mentioned
B. they move in unison while assuming- they doesn't has clear referent.

D.. "yet" is used succinctly to show the contrasting nature of the fact,that makes it interesting.

Trust the timing of your life!

An interesting fact about the human ear is that in the cochlea, hair cells are placed close to each other, moving in unison and assuming distinct cell shapes independent of one another.

A. moving in unison and assuming
B. they move in unison while assuming
C. move in unison, and assume
D. moving in unison yet assuming
E. even though they move in unison and assume

This is a simulated version of the GMAT Prep question, given below; the Industry seems to thrive on such imitations.

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 adopt

However, in the heart beat case, the heart cells beating in unison is an effect of the adherence to one another, because when they adhere, they can't escape unified action. However in the ear cells case, being placed close to one another does not have to necessarily end in moving in unison. So, the use of the adverbial modifier 'moving' is suspect

This is a sly pitfall that the author of the look-alike version has missed

A - Incorrect:

The aggregation word and is used illogically to provide contrasting information. While grammatically correct, the use of and fails to express the contrasting behavior of hair cells that move together but take on different shapes.

B - Incorrect:

The two independent clauses are connected with a comma, but a semicolon is required.

C - Incorrect:

This answer is not grammatically correct. The use of move in unison, and assume would need the conjunction and to make it part of a verb phrase: are placed…, and move in unison, and assume. And, even then, it would be awkward and unidiomatic.

D - Correct:

The aggregation word yet is used correctly to show contrast. This answer choice is the one that would best explain why such phenomena are interesting to scientists and to us.

E - Incorrect:

This answer does not make sense. What’s surprising is not that the cells are placed close together.

hello sir daagh GMATNinja

The correct choice will be



i am not able to find the verb of the subject the cochlea

please explain
