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.

Hello Shraddha.

Just to make understand better your comment:what you are basically saying is that if, in C, we had a "Contributes" instead of "Contributing" would make the choice valid?

Thanks,

Gabriel.





Hello @Gabrielantonioreis/ Gabriel,


Thank you for the query. :-)

Yes, you got it correct. if we turn contributing to contributes in Choice C, then each will become subject with the verb contributes. After the comma we will have a dependent clause. This structure will be valid.


Hope this helps. :-)
Thanks.

Hello tireks,


I would be glad to help you resolve your doubt. :-)

See, the GMAT SC rules are used only in creating SC problems. The outside world does not use GMAT SC to write articles, features, stories, reports, etc. Hence, the usage we consider incorrect on GMAT SC may be commonly used outside the GMAT world. Hence, we experts always back our explanation with official questions and go by the correct official answers.


Hope this helps. :-)
Thanks.

(A) of all the other planets, each contributing according to their - use of plural “their” with singular “each”
(B) of all the other planets, with each of them contributing according to their - same as A
(C) all the other planets, each of which contributing according to its - “which” should introduce a clause -- there is no verb here
(D) all the other planets, each contributing according to its - Correct
(E) all the other planets, each of which contribute according to their - use of plural “their” with singular “each”

Answer D

A. "their": each is singular, should be it
B. "their" like the above reason + "with" is unnescessary
C. "contributing" is a V-ing. Should be a Verb after "each of which"
D CORRECT
E. "their": each is singular, should be "it"
Choose D
