Hello Everyone!

Let's take a closer look at this question, since it appears that the original posting had to be updated at some point to fix typos. We'll look at each option and narrow it down to the right answer. To get started, here is the question with any major differences between each option highlighted in orange:

The remarkable similarity of Thule artifacts throughout a vast region can, in part, be explained as a very rapid movement of people from one end of North America to the other.

(A) The remarkable similarity of Thule artifacts throughout a vast region can, in part, be explained as
(B) Thule artifacts being remarkably similar throughout a vast region, one explanation is
(C) That Thule artifacts are remarkably similar throughout a vast region is, in part, explainable as
(D) One explanation for the remarkable similarity of Thule artifacts throughout a vast region is that there was
(E) Throughout a vast region Thule artifacts are remarkably similar, with one explanation for this being

Right away, if we just read the orange parts in each option, we start to see some problems:

(A) The remarkable similarity of Thule artifacts throughout a vast region can, in part, be explained as

This answer is INCORRECT because it's saying that the similarity of Thule artifacts IS a rapid movement of people from one end of North American to another, which doesn't really make logical sense. It should say that the similarity is CAUSED BY a rapid movement of people. It's also not clear that this is only ONE explanation of many - it just says that this partly explains the similarity of artifacts.

(B) Thule artifacts being remarkably similar throughout a vast region, one explanation is

This is INCORRECT because it's unclear what the subject of the sentence is. The phrase "Thule artifacts being remarkably similar throughout a vast region" needs a verb directly after it to work because it is acting like a subject here. "One explanation" is also acting as the subject. We can't have two subjects that are just stacked on top of each other like this, with nothing connecting them.

(C) That Thule artifacts are remarkably similar throughout a vast region is, in part, explainable as

This is INCORRECT for the same reason as option A. If you read carefully, it says that the phenomenon of similar artifacts IS the movement of people, not that it was CAUSED BY a sudden movement of people. This doesn't make logical sense, so let's toss this option aside.

(D) One explanation for the remarkable similarity of Thule artifacts throughout a vast region is that there was

This is CORRECT because it conveys the proper meaning (the movement of people is one explanation for finding similar artifacts in several places), and this is absolutely clear to readers. This isn't to say this option is perfectly grammatically correct - many of you took issue with the phrase "is that there was" being overly wordy. However, this is the best answer because it conveys its meaning the clearest - even if you could argue that you could cut a few words out.

(E) Throughout a vast region Thule artifacts are remarkably similar, with one explanation for this being

This is INCORRECT because the first clause "Throughout a vast region Thule artifacts are remarkably similar" is missing a comma after the word region.

There you have it - option D is the correct answer! This was a difficult question, for sure!

OG Official Explanation



Logical predication; Grammatical construction; Rhetorical construction

The intended meaning of the sentence is that the rapid movement of people across North America is one explanation of the similarity of Thule artifacts throughout a vast region. As worded, however, the sentence is illogical: The sentence indicates that the similarity in artifacts was a rapid movement of people, which makes no sense. Instead of equating similarity with movement, the sentence needs to identify this movement of people as a cause of similarity among artifacts.

A As worded, this version of the sentence makes the illogical statement that the similarity among artifacts is explainable as a very rapid movement. It should specify that the similarity of artifacts may be a consequence of the rapid population movement.

B This version of the sentence is syntactically awkward, and leaves unclear what the main subject, one explanation is supposed to be an explanation of.

C Like (A), this version of the sentence equates the similarity of artifacts with the movement of people, when a causal connection is what is intended.

D Correct. This version adequately expresses the intended causal connection.

E This version is awkward, introducing the causal connection with the unnecessarily wordy and indirect string of prepositional phrases, with one explanation for this. . . .

The remarkable similarity of Thule artifacts throughout a vast region can, in part, be explained as a very rapid movement of people from one end of North America to the other.

(A) The remarkable similarity of Thule artifacts throughout a vast region can, in part, be explained as When you examine the logic of this option, you will realise that this option sis saying that the similarity of Thule artifacts is a rapid movement of people from one end of North American to another, which doesn't really make logical sense. When an explanation is being offered, the phrase used should be “explained by”

(B) Thule artifacts being remarkably similar throughout a vast region, one explanation is “Thule artifacts being remarkably similar throughout a vast region” is a modifier that is telling us about the subject. The subject should immediately follow the comma. But in this options the subject seems to “one explanation.”

(C) That Thule artifacts are remarkably similar throughout a vast region is, in part, explainable as This option says that the phenomenon of similar artifacts IS the movement of people, not that it was CAUSED BY a sudden movement of people. This doesn't make logical sense.

(D) One explanation for the remarkable similarity of Thule artifacts throughout a vast region is that there was This option clearly explains that the very rapid movement of people from one end of North America to the other is one explanation for the remarkable similarity of Thule artifacts throughout a vast region.

(E) Throughout a vast region Thule artifacts are remarkably similar, with one explanation for this being If there were a comma after “Throughout a vast region”, this option would be clearly referring to what is the case throughout a vast region.

Dear Friends,

Here is a detailed explanation to this question-
blockman
The remarkable similarity of Thule artifacts throughout a vast region can, in part, be explained as a very rapid movement of people from one end of North America to the other.


(A) The remarkable similarity of Thule artifacts throughout a vast region can, in part, be explained as

(B) Thule artifacts being remarkably similar throughout a vast region, one explanation is

(C) That Thule artifacts are remarkably similar throughout a vast region is, in part, explainable as

(D) One explanation for the remarkable similarity of Thule artifacts throughout a vast region is that there was

(E) Throughout a vast region Thule artifacts are remarkably similar, with one explanation for this being


Meaning is crucial to solving this problem:
Understanding the intended meaning is key to solving this question; the intended meaning of this sentence is that one explanation for the remarkable similarity of Thule artifacts throughout a vast region is that there was a very rapid movement of people from one end of North America to the other.

Concepts tested here: Meaning + Awkwardness/Redundancy

• “being” is only to be used when it is part of a noun phrase or represents the passive continuous verb tense; the use of passive continuous must be justified in the context.

A: Trap. This answer choice alters the meaning of the sentence through the phrase "explained as"; the use of "as" illogically implies that the remarkable similarity of Thule artifacts throughout a vast region was partially a very rapid movement of people from one end of North America to the other; the intended meaning is that the remarkable similarity of Thule artifacts throughout a vast region was partially caused by a very rapid movement of people from one end of North America to the other.

B: This answer choice is awkward and needlessly indirect due to its use of the word "being"; please remember, “being” is only to be used when it is part of a noun phrase or represents the passive continuous verb tense; the use of passive continuous must be justified in the context.

C: This answer choice alters the meaning of the sentence through the phrase "explained as"; the use of "as" illogically implies that the fact that Thule artifacts are remarkably similar throughout a vast region was partially a very rapid movement of people from one end of North America to the other; the intended meaning is that the fact that Thule artifacts are remarkably similar throughout a vast region is in part because of a very rapid movement of people from one end of North America to the other

D: Correct. This answer choice uses the clause "One explanation...is that there was", conveying the intended meaning - that the intended meaning is that the remarkable similarity of Thule artifacts throughout a vast region was partially caused by a very rapid movement of people from one end of North America to the other. Further, Option D avoids the modifier error seen in Option E, as it does not employ the "phrase + comma + noun" construction. Additionally, Option D is free of any awkwardness or redundancy.

E: This answer choice fails to maintain the "phrase ("Throughout a vast region") + comma + noun ("Thule artifacts")" construction, as it omits the comma. Further, Option Option E uses the passive voice construction "with one explanation for this being", leading to awkwardness and redundancy.

Hence, D is the best answer choice.

To understand the use of "Being" on GMAT, you may want to watch the following video (~2 minutes):



All the best!

I think it should be D.
A. The remarkable similarity of Thule artifacts throughout a vast region can,in part,be explained as
B. Thule artifacts being remarkable similar throughout a vast region (no verb), one explanation is
C. That Thule artifacts are remarkable similar throughout a vast region, in part, explainable as
D. One explanation for the remarkable similarity of Thule artifacts through a vast region is that there was-- PERFECT
E. Throughout a vast region Thule artifacts are remarkable similar, with one explanation for this being

B,C,E are out because it should have been remarkably
A is out because there should be some word like "can" before be explained as.. otherwise it is awkward in construction

daagh: Is the usage of "Explained as" incorrect in GMAT? If not, can you please provide few examples to demonstrate the usage of "explained by" and "explained as".

Also, I felt that D changes the meaning of the sentence. In option D, the usage of "One explanation" adds more information to the information stated in the question. In what circumstances does GMAT permit such changes to the meaning.

I had a query regarding the meaning of the option choices in the following question

OG 2016 : Question 31 : SC : Thule Artifacts


The remarkable similarity of Thule artifacts throughout a vast region can,in part,be explained as a very rapid movement of people from one end of North America to the other.

A. The remarkable similarity of Thule artifacts throughout a vast region can, in part, be explained as
B. Thule artifacts being remarkably similar throughout a vast region, one explanation is
C. That Thule artifacts are remarkably similar throughout a vast region is, in part, explainable as
D. One explanation for the remarkable similarity of Thule artifacts throughout a vast region is that there was
E. Throughout a vast region Thule artifacts are remarkably similar, with one explanation for this being

Original sentence conveys that similarity of the artifacts can be partly explained. It can't be explained fully.
Option Choice D says that one explanation for the similarity is ... This means that there can be many explanations for the similarity, but one explanation is this one.

Though the option D is grammatically correct, I ruled out the choice because it deviated from the meaning stated in the original sentence.

Is the deviation allowed in the meaning of the original sentence?

Please clarify how the option choice D is the correct answer.

Thanks

Sahil

Hi Sahil,

Option D is grammatically and logically correct.

Original sentence: The remarkable similarity of Thule artifacts throughout a vast region can, in part, be explained as a very rapid movement of people --> Remarkable similarity can be explained as a very rapid movement of people? This is illogical.

D) One explanation for the remarkable similarity of Thule artifacts throughout a vast region is that there was a very rapid movement of people --> This choice is perfectly fine and logical.

Hope it helps.

Can you please provide a definition (like a dictionary one) for "explained as" and for "explained by"?
Are they both phrasal verb?

I still don't get why answer A is wrong. For me "can be explained as" means "we can explain it with the following reason...", "we can say it is due to...."

Thanks in advance

If you go with the meaning of the sentence, we have 'The reason for similar artifacts throughout vast region is movement of people from one place to another'.

Now if you look at original sentence, the meaning implies 'similarity can be explained as something' It is very non-sensible. We are not explaining the similarity but we are explaining the reason behind the similarity. Hence, A is illogical.

The remarkable similarity of Thule artifacts throughout a vast region can,in part,be explained as a very rapid movement of people from one end of North America to the other.

D clearly tells the intended meaning, hence is the correct answer.

Explained as means we are defining something. Here, we are not defining similarity but we are providing the reason behind similarity.

Explained by means we are using something to define it.

C. That Thule artifacts are remarkably similar throughout a vast region is, in part, explainable as
D. One explanation for the remarkable similarity of Thule artifacts throughout a vast region is that there was
E. Throughout a vast region Thule artifacts are remarkably similar, with one explanation for this being

OA: D
Can someone please explain what is wrong with E

Sorry: fixed answer choices, should be "remarkably" in B,C,E

Responding to a pm:

When you explain A as B, you are equating the two.

Here are a couple of real world examples of the usage:

The racial bias observed is not explainable as a response to local-level crime rates.
How cluster headache is explained as an intracavernous inflammatory process lesioning sympathetic fibers... (Heading)

When you want to give the cause of a certain phenomenon, you use "explain by"

Tomasetti and Vogelstein conclude that these differences can be explained by the number of stem cell divisions.

In options (A) and (C), the similarity of objects is because of the rapid movement of people. So "explained as" is not correct.

Yes! Absolutely!

"Explained by" is the correct way to express a reason/cause for something.

"Explained as" is used when you are equating two things.

Example - John's results can be explained by analyzing his strategy.

The incorrect version - John's results can be explained as analyzing his strategy. You'll notice that this structure does not lend the meaning nicely.

Tip - Simplify the sentence and look at the structure. It helps in zeroing in on the correct choice.

Hope this helps!

Best,
SS18

Hello Prashant10692,

I will be glad to help you out with this one. :-)

In the correct answer choice D, that is a connector/conjunction that joins the preceding independent clause with the following dependent clause.

Basically, the entire that clause acts as an object of the verb is.


Hope this helps. :-)
Thanks.
