Modeling the formation of the terrestrial and gas giants is relatively straightforward and uncontroversial because the terrestrial planets of the solar system are widely understood to have formed through the collision of micro-planets within the newly formed disk of gas surrounding the sun.
A) giants is relatively straightforward and uncontroversial because the terrestrial planets of the solar system are widely understood to have formed through the collision of micro-planets
B) giants is relatively straightforward and uncontroversial because the terrestrial planets of the solar system widely understood to have formed through the micro-planets' colliding
C) giants are relatively straightforward and uncontroversial because the terrestrial planets of the solar system are widely understood to have formed through the colliding of micro-planets
D) giants are relatively straightforward and uncontroversial because the solar system's terrestrial planets are understood widely to have formed through the collision of micro-planets
E) giants is relatively straightforward and uncontroversial because of the wide understanding that the formation of the terrestrial planets of the solar system were caused by the collision of micro-planets

OFFICIAL EXPLANATION
For a quick POE, scroll down to the next GREEN HEADING
THE PROMPT
THE OPTIONS
-- modeling is a gerund (a verbING), and gerunds are always singular, so the correct verb is the singular IS
-- collision (dedicated noun) is more idiomatic than colliding (___ING verb-like noun form). Dedicated nouns are preferred to gerunds.
-- micro-planets' colliding?
1) collision, as in Option A, is better than __ING collding; and
2) inanimate objects, especially if plural, should be written as Y of the Xs (collision of micro-planets)
rather than Xs' Y (micro-planets' colliding)
-- the dedicated noun collision, as in option A, is preferred to the __ING noun form colliding
-- words in pink typeface are clumsy compared to their counterparts in option A
-- words in pink: compare to option A. Option A says the same thing as E in fewer words and more clearly.
Almost always, the most efficient way to answer SC questions is to use "splits," a method described in these three very good articles:
(1) GMAT Sentence Correction Strategies, here;
(2) Using Splits on GMAT Sentence Correction, here; and
(3) How to Read a GMAT SC Problem, here..
Using splits is not always possible. Harder questions often cannot be solved using splits because the test writers don't group any errors or they do group errors but the errors are written differently in each incorrect response, so our eyes can't spot the grouping.
This question is good for using splits on the first pass to eliminate two answers. After that, it's probably easiest to compare one answer to another.
Quick POE
• Split #1: subject/verb agreement
Modeling . . . IS, not
Modeling . . . are
Eliminate options C and D, which incorrectly pair the singular subject modeling with the plural verb are
• Split #2: the missing verb
Option A: the terrestrial planets of the solar system are widely understood to have XYZed
Option B: the terrestrial planets of the solar system widely understood to have XYZed
Eliminate Option B because it is missing the verb ARE.
• Split #3: Subject/verb agreement
Option A: formation . . . was
Option E: formation . . . were
Eliminate option E, which incorrectly pairs singular subject formation with plural verb were
By POE, the answer is A
In this question, the splits are clean cut—that is, subject/verb agreement and a missing verb are clear errors.
The articles above discuss splits that are less clean cut and how to handle them.
One of the tricks in any standardized test is to avoid getting stuck or frozen. If you can't see a clear split, use an educated guess.
In option B, for example, some people noticed and did not like option B's use of the micro-planets' colliding.
Good instincts.
The dedicated noun collision is preferred to the ___ING form colliding.
Plural possessives are correct only about 30 percent of the time.
-- That estimate may be high. MGMAT says 20%.
-- And if all else is equal, the better way to indicate possession when inanimate things are involved is to use Y of the Xs rather than Xs' Y.
I think almost everyone eventually caught that option B was missing a verb, but I think B's clumsy construction caught attention first. That fact is just fine. Do whatever it takes to keep your mind from freezing.
COMMENTS
thinkvision (cool username), welcome to SC Butler.
I really enjoy reading the "extra" comments people make.
Kudos to all because with varying degrees of success, everyone explained (even if someone did take a well-deserved break or slid in after the 24-hour mark
).
Nice work, all.

THE OPTIONS
Quote:
-- the subject is modeling (the plural noun giants, which appears immediately before the verb, is part of the complete subject).
-- modeling is a gerund (a verbING), and gerunds are always singular, so the correct verb is the singular IS
-- collision (dedicated noun) is more idiomatic than colliding (___ING verb-like noun form). Dedicated nouns are preferred to gerunds.
Quote:
-- terrestrial planets . . . . widely understood is missing a verb!
-- micro-planets' colliding?
1) collision, as in Option A, is better than __ING collding; and
2) inanimate objects, especially if plural, should be written as Y of the Xs (collision of micro-planets)
rather than Xs' Y (micro-planets' colliding)
Quote:
-- Modeling (the formation) . . . is a singular subject. The verb ARE is incorrect
-- the dedicated noun collision, as in option A, is preferred to the __ING noun form colliding
Quote:
-- plural verb ARE is fatal
-- words in pink typeface are clumsy compared to their counterparts in option A
Quote:
-- formation is singular. Its verb should be was. (Long prepositional phrases are often used by GMAC to hide the subject)
-- words in pink: compare to option A. Option A says the same thing as E in fewer words and more clearly.

generis
A) giants is relatively straightforward and uncontroversial because the terrestrial planets of the solar system are widely understood to have formed through the collision of micro-planets - Correct
B) giants is relatively straightforward and uncontroversial because the terrestrial planets of the solar system widely understood to have formed through the micro-planets' colliding The highlighted part lacks verb + Awkward usage of possessive in "micro-planets' colliding"
C) giants are relatively straightforward and uncontroversial because the terrestrial planets of the solar system are widely understood to have formed through the colliding of micro-planets - S-V error. Subject is the present participle "Modeling" which requires singular
D) giants are relatively straightforward and uncontroversial because the solar system's terrestrial planets are understood widely to have formed through the collision of micro-planets- S-V error. Subject is the present participle "Modeling" which requires singular
E) giants is relatively straightforward and uncontroversial because of the wide understanding that the formation of the terrestrial planets of the solar system were caused by the collision of micro-planets- Incorrect usage
