Then there is a very little difference between A and D,
Can any one please let me know if the following sentences are correct and is it ok to write in this way:

IMO both seem to be correct.
In 1), "of" is explicitly mentioned and in 2), it is not. Even if it is not, then also it is implied to the latter part.
Would be eager to hear from the rest of the guys.

I would give my 2-cents. Firstly I believe, these two as choices would not be given by GMAT as technically both of them are correct. However, from my perspective, I will pick 2nd choice as an additional 'of' is removed making the sentence more shorter.

In correct answer choice 'each contributing....' is a modifier that modifies the main clause, right? Why there is no verb in this modifier? can someone please explains it to me. Thanks

It is actually an absolute phrase that answers the HOW aspect of the preceding clause.

Hi Raj

'its' is referring to 'each' and not 'planets'

Let's look at the sentence:

In his experiments with gravity, Isaac Newton showed how the motion of each planet in the solar system results from the combined gravitational pull of the Sun and of all the other planets, each contributing according to their mass and distance from the others.

their (plural ) can't be paired with each (singular) and thus, A, B, and E can be eliminated.

A. of all the other planets, each contributing according to their- wrong pronoun
B. of all the other planets, with each of them contributing according to their- wrong pronoun
E. all the other planets, each of which contribute according to their- wrong pronoun

We are down to two now

C. all the other planets, each of which contributing according to its

Use of 'each of which' is imprecise here. 'each of which' like 'which' requires a verb after that. As there is no verb after 'each of which', the construction is imprecise.

Correct use of 'each of which' -
select any two answer choices, each of which can be used to complete the sentence.
I have bought several books, each of which is based on a different theme.


D. all the other planets, each contributing according to its

Answer D

Hope it helps!
Dolly :)

Yes, "their" is wrong because it doesn't agree with "each."

You can't say "each of which contributing." Adding "of which" makes "each" into a subject which would then need the verb "contributes."

In D, "each contributing" serves as a modifier--"each" doesn't serve as a subject.

Compare these:

The lobby was full of aspiring actors, each dreaming of landing a big role.
The lobby was full of aspiring actors, each of whom dreamed of landing a big role.

Those both work. What we wouldn't want to say is this:

The lobby was full of aspiring actors, each of whom dreaming of landing a big role.

Hopefully, that sounds awful to you! The sentence we're dealing with here works in the same way.

IMO - D, as explained below:

In his experiments with gravity, Isaac Newton showed how the motion of each planet in the solar system results from the combined gravitational pull of the Sun and of all the other planets, each contributing according to their mass and distance from the others.
A. of all the other planets, each contributing according to their => SVA issue
B. of all the other planets, with each of them contributing according to their => SVA issue
C. all the other planets, each of which contributing according to its => unnecessarily heavy construction
D. all the other planets, each contributing according to its => precise and correct
E. all the other planets, each of which contribute according to their => SVA issue

Ans = D
Original sentence has pronoun issue. 'their' does not match with 'each'. Hence Eliminate A, B and E
C is extremely wordy (each of which contributing....)

Option D..
Each:its. We cant use their..
This eliminates A,B and E. In Option C, the construction is wrong..
Either "each of which is contributing according to its", or "each of which contributes according to its"-- will do fine. Here it is "each of which contributing according to its" which is wrong.. Hope this helps..

between C & D:
[credit to eGmat] Choice C is incorrect because “which” should introduce a clause. There is no verb after “which” that makes the choice incorrect.

PS: "Which" introduces non essential clause whereas "contributing" here is a participle.

Hi Dmitry,

Can you shed some more light on "each of which" and "each of whom" constructions from a grammatical standpoint.
I mean I couldn't grasp how each of whom/each of which can act as a subject , while a singular each can't. :?

Thanks,
SR

It's not that a solitary "each" can't serve as a subject--it's that it doesn't have to. The word "each" can serve as either a pronoun or a modifier (adjective/adverb).

Pronoun: Each one of these paintings is worth a million dollars.
Modifier: There are three bedrooms, each with its own bathroom.

However, we can also use "each" as a pronoun in a modifying clause. In this case, we use "of which/of whom" to signal that we are building such a clause.

He ordered several different dishes, each of which could have served as a meal in its own right.

Here, "each" is the subject and "could" is the main verb. We typically do this to express something more complicated than we could in a normal modifier. Notice that because we have a complex set of verbs ("could have served"), it would be hard to express this without a full clause. If we said "each serving as a meal in its own right," that would change the intended meaning (each dish actually is a meal).

I hope that helps!

If you use contributes, then it will be a verb, resulting in a run on sentence. hence it is not correct.

Each always singular so the last pronoun must be "its"

So we can cross out A B and E

In between C and D

"Each of which" is wordy and some what redundant so D is the better One .

Hi DmitryFarber, as I studied earlier, each can have both plural and singular noun depending whether we have plural noun before or after "each".

e.g.
The three networks each: Plural
Each of the three networks: Singular

Is this concept wrong? Over here each came after plural noun so why we don't have plural pronoun? Is it because of comma between plural noun and each?

No, "each"' is always singular. It is correct to say "The three networks each provide similar programming," but only because in this case "each" is not the subject, but a modifier. The subject is "the three networks," which is of course plural.

So if you see "Each of . . .," "each" is serving as a singular noun. However, if you see "The [plural noun] each," then "each" is serving as a modifier on the verb, which should in turn agree with the plural subject.

All of the options mention 'each'. Each needs a singular pronoun. Hence, all options with 'their' are incorrect.

A. of all the other planets, each contributing according to their It is needed instead of their

B. of all the other planets, with each of them contributing according to their It is needed instead of their

C. all the other planets, each of which contributing according to its contributing should be contributes. Else use an auxiliary verb with the present participle form (in this case 'is')

D. all the other planets, each contributing according to its Correct

E. all the other planets, each of which contribute according to their It is needed instead of their
