A ...I guess "their" refer to "planets"

of the sun and of all the other plants ..we need "of" to qualify the noun

Why is of wrong in A and B? It is parallel.
combined gravitational pull of the sun and of all the other planets

What is the correct use of of which?

It says COMBINED gravitational pull of sun and other planets...

if you repeat OF before other planets - it'll become the combined gravitational pull of sun and the combined gravitational pull of other planets which would obviously be absurd.

'Each of' expects either dependent clause or noun following it. But there is a pronoun 'Which', that follows without a dedicated [verb +noun] - incorrect . misplaced/dangling modifier

The brutal SC doc. has the answer as

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.

the 'and' is connecting gravitational pull " of the sun" and "of all the other planets" - so C,D,E can be eliminated since they dont start with "of"

A. of all the other planets, each contributing according to their
B. of all the other planets, with each of them contributing according to their

between A and B , in B 'with' is wrong

I am still not sure why thier and not its ---

According to me,there are only two options left c and d.
In all other options we are using their with each .which is incorrect usage.
Hope it will help

I choose C but now I agree that option D is better.

Each is referring to Gravitational pull of Sun,planets..and Each always takes a singluar pronoun.As a subject of sentence, each or every requires a singular verb form.
Ex: Each dog has paws.
: Every dog and cat has paws.
: Each of these shirts is pretty.

except SANAM (Some, Any ,None, All, More/most) Pronouns. These indefinitive pronouns can be either singular or plural depending upon the context of sentence. Watch out for "Of phrase" which will guide you towards numbers.

One catch ball is there with usage of Each...
Please see that each following a subject has NO Bearing on the verb form.

Ex: They each are great tennis players.

Here, the plural subject "They" preceeds each, and hence requires the plural form Are.

Hi . I understand that you are referring to usage of each from MGMAT ..but in the example that u mentioned above they is before" each " and becomes the subject ...
however in the question above each is before the word planets and hence should take a singular pronoun as well i.e its and not their ( as given in E)

its a case of faulty ellipsis here.. you don't need another "of" here .. the first one follows the suit for the second too.. of (the Sun and the planets)

Plus, D also uses the correct subject verb agreement.. each contributing according to its

Each is singular. So down to D and C. "of which" is redundant. Hence D remains.

A, B and E are wrong because antecedent of "their" is sigular....

between C and D... C is wrong because dangling modifier...

It can be ,but it will give redundancy and that is no - no for GMAT.

51. 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
B. of all the other planets, with each of them contributing according to their
C. all the other planets, each of which contributing according to its
D. all the other planets, each contributing according to its
E. all the other planets, each of which contribute according to their

I wasn't sure of 'of all'/ 'all the other' split because they both seemed okay to me.

As far as I know, you can't get rid of the choices strictly according to the ambiguity of antecedent usage.
I was thinking about the followings,
its = each of planets and the sun
their = the sun and all the other planets

Thanks.

Hi There,

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
B. of all the other planets, with each of them contributing according to their
C. all the other planets, each of which contributing according to its
D. all the other planets, each contributing according to its
E. all the other planets, each of which contribute according to their

Notice that each answer choice has “each” that makes the subject singular. Even if “each” is referring to “Sun and all the other planets”, it turns all the entities into singular. Hence, when we use “each” to talk about “Sun and all the other planets”, the pronoun that we use to refer to those entities that actually stands for “each” should be singular.

So in this problem, we have a case of pronoun antecedent number disagreement and not the ambiguity. We can eliminate Choices A, B, and E because of the use of plural “their” with singular “each”.

Choice C is incorrect because “which” should introduce a clause. There is no verb after “which” that makes the choice incorrect.

Choice D is precise and free of errors.

Hope this helps.
Thanks.
