Continents to split apart

by gmatrant » Fri Jul 02, 2010 11:11 pm
New theories propose that catastrophic impacts of asteroids and comets may have caused reversals in the Earth's magnetic field, the onset of ice ages, splitting apart continents 80 million years ago, and great volcanic eruptions.
(A) splitting apart continents
(B) the splitting apart of continents
(C) split apart continents
(D) continents split apart
(E) continents that were split apart

The answer is A. I agree. I just wanted to confirm the below.
If D read "continents to split apart", is this right grammatically?

What is wrong with option B here? It looks parallel to me..

New theories propose that catastrophic impacts of asteroids and comets may have caused reversals in the Earth's magnetic field, the onset of ice ages, the splitting apart of continents 80 million years ago, and great volcanic eruptions.

Apologies OA is B not A. (that was a typo).

Please answer my question. I agree with the OA, but want to clarify a concept.

How do you choose between A and B ?

the sentence does say the onset ...... but it doesnt say the reversals or the great volcanic eruptions .

Its a parallelism in Noun form.

Splitting is a verb but according to grammer rules, adding THE to the progressive verb makes it noun or gerund to be precise.

The onset, reversal, eruptions and the splitting all are noun.

hope that helps!

"split apart continent" is definitely a verb here, not the gerund/noun that is required to maintain parallelism.
Yep.

Isn't this correct:

New theories propose that catastrophic impacts of asteroids and comets may have caused split apart continents.

?

- He could see the split apart continents from the outer-space.

@uwhusky
C - I do not think that split apart in split apart continents is a verb.
This is because then, the sentence would completely break down. Notice the non underlined parts -
- caused reversals in the Earth's magnetic field, the onset of ice ages..., and great volcanic eruptions

The parallel parts here are -
Catastrophic impacts of asteroids and comets may have caused
1. reversals in the Earth's magnetic field (noun phrase)
2. the onset of ice ages (noun phrase)
3. great volcanic eruptions (noun phrase)

Now notice the underlined part in C-
split apart continents - if split is a verb, then we are introducing a verb and an object in between three parallel noun phrases. This cannot be correct.

Actually in option C, split apart is an adjective modifying continents. So split apart continents is a noun phrase.

@clawhammer -
As written above, in option C,
split apart continents is a noun phrase with split apart modifying continents. Hence, this is parallel with the other noun phrases. However, the meaning is distorted.

Notice the parallel structure -
Catastrophic impacts of asteroids and comets may have caused -
1) reversals in the Earth's magnetic field
2) the onset of ice ages
3) split apart continents
4) great volcanic eruptions

This would mean that asteroid impacts have caused split apart continents (adjective-noun). Now, clearly, impacts did not cause continents, rather impacts caused the splitting apart of continents.

That is why option C is wrong and B is right.

@niksworth

I guess we can agree that C is incorrect for different reasons. IMO, "split apart" to me is an incorrect usage of verb, thus C is wrong.

Edit: I just verified that this is indeed an OG question, which is question #119 (12th edition).

The explanation in the back of the book is also calling C an incorrect usage of verb.

I think if it is used as an adjective, it should be in participle like most verbs that are used as adjectives. Furthermore, GMAT makes it easier by using articles in front of the gerunds to signal that it is a gerund as oppose to a verb or verbal.
Yep.

@uwhusky

Agreed. Since C is incorrect, the same phrase cannot be correct for one reason while incorrect for the other. It must be incorrect for both. Silly me :)
