(A) splitting apart continents - is a participle, therefore not correct for parallelism.
(B) the splitting apart of continents - noun because the article "the" changes the participle "splitting apart" into a noun, therefore it looks good
(C) split apart continents - verb, therefore no
(D) continents split apart - although this option starts with a noun, none of the other items on the list has a verb. therefore, "split" ruins the parallel structure.
(E) continents that were split apart- no where in the other items in the list has any relative pronouns


I would say B because we have a list of nouns, and some nouns have adjectives as well. Adjectives don't interfere with the nouns, so we have to look for an answer choice that would have either a noun or a noun with an adjective.

Sentence has “nouns” parallelism issue

(A) splitting apart continents (“splitting” acts as a participle, but require a noun – Eliminate it)
(B) the splitting apart of continents (“the splitting” is a gerund – Hold it)
(C) split apart continents (Not parallel – Eliminate it)
(D) continents split apart ( Not parallel – Eliminate it)
(E) continents that were split apart ( Not parallel – Eliminate it)


Answer: B

119) 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 imp thing in the question is check the construction : Cause -> Effect

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.

Now these 4 should be parallel - the splitting apart of continents ( complex gerund mostly constructed by the +simple gerund+ of ..)

We have a list of noun phrases here -

reversals in the Earth’s
the onset of ice ages
volcanic eruptions

(A) splitting apart continents - this is a verb and conveys that preceding action did the splitting
(B) the splitting apart of continents - "of" makes the difference here..."the splitting" becomes the noun phase
(C) split apart continents - "split" again acts as verb - we need a noun - thats why this stands incorrect in the context
(D) continents split apart - change of meaning
(E) continents that were split apart - incorrect

I hope this helps!

Action nouns are parallel to complex gerund phrases.

Only B satisfies the condition.

To maintain the parallelism of the sentence, the list that the impacts (reversal...., onset, ...splitting.... and ....eruptions) need to be parallel. As it stands in A the list goes noun, noun, verb, noun so we need to correct the verb phrase into a noun phrase.
A – eliminate because splitting is a noun
B – Correct. Splitting in this sense is a gerund and therefore a noun. This is achieved by the placement of ‘the’ and the conjunction ‘of’ which makes continents a modifier of the noun. Think of running, it’s an activity (i.e. a noun) and an action (i.e. a verb)
C – split is a verb in the infinitive, and hence isn’t the noun we’re looking for
D – Not sure how to explain this unless I simplify the sentence. Catastrophic impacts .... caused...SPLIT APART CONINENTS. As is stands, this sentence says that the asteroids created the continents (which are split) rather than creating the action of splitting the continents.
E – Again, this sentence says that the continents were created, rather that the action of splitting.

(A) splitting apart continents
(B) the splitting apart of continents CORRECT
(C) split apart continents
(D) continents split apart
(E) continents that were split apart

It is not C because the sentence - the splitting apart of continents - says that some action lasted in past, that it was a process and not just one moment in time...and C doesn't emphasise that it was a process, but something that asteroids and comets usually do. This is how I've understood it.

B is the right answer because it maintains parralelism by the use of a gerund phrase.

B is correct - action nouns such as "reversal" can be parrallel to complex gerunds such as "splitting apart of continents" but not to simple gerunds such as "splitting apart continents"

Hello,

Let me see if I can work this one through....


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.

OK, from the question it looks like this is a parralelism issue. We have a list of things that 'catastrophic impacts of asteroids and comets' may have done, but right now the current underlined sections seems to be out of kilter with the rest of the list. Look at each of the items in turn:

reversals in the Earth’s magnetic field
the onset of ice ages,
splitting apart continents 80 million years ago
and great volcanic eruptions.

It is clear that the red section, which equates with the underlined is out of sync. It's the only one with an 'ing' i.e. an action occuring. Everything else is different.

Looking at the answer options gives us a clear winner...


(B) the splitting apart of continents. And here it is by adding the 'the' we change the meaning, and it becomes a statement like the others, rather than something happening.
(C) split apart continents This 'split' is in the past tense - unlike anything else
(D) continents split apart Again past tense
(E) continents that were split apart Once more an action occuring in the past

Hope that helps...

Thanks Your Answer was correct.
But where I was facing the problem is that I dont get the concept when you say
- "And here it is by adding the 'the' we change the meaning, and it becomes a statement like the others, rather than something happening"

the explanation says that "reversals, the onset, eruptions" are nouns and adding "the" with "splitting" makes it a noun.

Can you please explain the rule to me in detail. What is the concept behind this.

It is is all having a noun in the phrase. we have "continents split apart" Option D
