I am afraid lots of misconceptions are going round in regard to this text. First of all, ‘each one’ is not redundant. Each can be used both as a noun (when you say just each) and as an adjective when it modifies another noun as in each person, or each one etc. But D is wrong because of the intruding conjunction ‘and’ followed by a participial phrase rather than a full-fledged clause with an action verb. E is wrong because of S-V number disagreement – ‘each one’ of which ‘date’ - the verb should be ‘dates’ to match the singular subject each one
B a C are grammatically wrong because, both are using wrong tense of present perfect – ‘have dated’ and ‘has dated’, meaning that the dating has ended and is no more relevant.

A is the perfect choice with the use of the present participle phrase just modifying – both – and has no unnecessary conjunction.

Here is my take.

Always use BOTH when pointing out similarities and use EACH when pointing out differences.

In the original question, The Acoma and Hopi are dating back at least a thousand years(Trying to explain the similarities.) Hence BOTH should be the pick.

Obviously, from A and B, B is wordy. So the answer must be A.

A. both dating

C. and each has dated
D. and each one dating
E. each one of which date

Guys, I found the problem in meaning of the OA. OFFcourse 4 remainings problematic too. Need more reasonings on why OA is the OA? :-D


Option E and D have redundancy problem - Use of 'one' and 'each'

Option B is wordy and awkward 'both of which'

Now between A and C, A looks perfect as it uses correct parallel construction 'surviving' and 'dating'

So the best option is A.

what is the OA?

I'm not saying that EVERYTHING in the NYTimes is gramatically correct, but probably 99.999999% of it is.

This addresses a few of the previous posts. One post says that when something is the same, we should use "both" which is not true and this sentence is an example. As "style" goes when writing, it might be a better "style", but it is not incorrect to use "each" when describing something that is the same. With this sentence, the two baseball teams are similar in the games won.

I must modify the example somewhat to show my second point, in that when the subect is compound, the decision of whether to use "each" or to use "both" depends upon how the subject is used.

If you have "Miami and Los Angeles will play in the NBA Finals, both of which have already won at least one NBA title." This sentence is correct, while so is this one:

"Miami and Los Angeles will play in the NBA Finals; each has already won at least one NBA title."

A for using the right participle -dating -; B and C are out because of using
the perfect tense indicating that the dating back is about to end. The second part of D is a fragment while E has S-V disagreement

A

A. both dating
Use of present participle followed by both is correct.

B. both of which have dated
Present perfect suggests that these communities no longer exist

C. and each has dated
Coordinating conjunction introduces a separate idea rather than modify the communities.
Present perfect suggests that these communities no longer exist

D. and each one dating
Coordinating conjunction introduces a separate idea rather than modify the communities.
A complete clause must be followed by a coordinating conjunction and

E. each one of which date
Subject 'each one of which' is singular.

The Acoma and Hopi are probably the two oldest surviving Pueblo communities, both dating back at least a thousand years.
A. both dating
B. both of which have dated
C. and each has dated
D. and each one dating
E. each one of which date

My doubts:
1) I know that C and D are wrong in part because we need a modiphiyng phrase and not a parallel clause. However, how can be sure that an idea must be subordinated or kept independent from the main clause? For instance, if choice C were "and each is dating", would it be incorrect?
2) I read in other post that B is wrong not only because is wordy but because the tense is wrong. Because the action has concluded in the present and it is not going on. Is it right?, could someone provide a detailed explanation about it?
Thank you!

Answer should be "A" beacuse:

c,d,e:...has "each" which refers to the communities and hence it refers to all the members rather than just two mentoned.

b is wordy and hence eliminated.

What is a main factor and what is a subordinate factor? In the given case, the text wants to establish that the two sites are examples of the oldest communities; in proof of that, it gives the dating data. Therefore, the data are additional facts and supportive ideas to the main theme of oldness. Putting them on equal footing with the main clause using a co-ordinate conjunction namely ‘and’ will end up in alteration of intent. Hence, C and D are wrong. Even if C were to be amended grammatically as has been stated by metallicafan, it would not make an ideal choice as far as meaning is concerned.

B is wrong because, when you use the present perfect, you are trying to imply that both are doing the dating themselves and that the effect of dating is no more. The effect of dating namely that they are part of the oldest communities is going to be there forever and a universal fact. Therefore, we need to use a simple present tense to express such a feeling.

Though the answer has been given, I just want to share my part of discussion. Before advancing, many thanks to metallicafan for the question.
My take:
Always remember, there are two requirements of COMMA + ING construction:
a) it should be adverbial, modifying the entire previous clause
b) it should be attributed to the subject of the previous clause.

The options C and D neither explain the preceding clause nor become a consequential effect.
Same goes for e as well.
Now when we move to B, here we see a change of tense which is nog required at all, in fact is incorrect.
Hence A.

Please give me kudos, if you liked the post.

The Acoma and Hopi are probably the two oldest surviving Pueblo communities, both dating back at least a thousand years.

A. both dating
Correct. Verb-ing modifier + comma --> modifies a preceding clause.==> "dating" is verb-ing modifier that provides more information for the preceding clause (why Acoma & Hopi are the oldest surviving Pueblo communities).

B. both of which have dated
Wrong. "which" should modifies the closest noun --> "which" modifies "communities", not "Acoma & Hopi" --> Wrong.

C. and each has dated
Wrong. "each" of communities or "each" of "Acoma & Hopi"??? --> Very obscure.

D. and each one dating
Wrong. Same error as in C. "each" of communities or "each" of "Acoma & Hopi"??? --> Very obscure.

E. each one of which date
Wrong. Same error as in B. "which" should modifies the closest noun --> "which" modifies "communities", not "Acoma & Hopi" --> Wrong.

Hope it helps.

E is a simple subject-verb issue. It should be each . . . dates.

In B, "have dated" doesn't make sense. Dating in this sense is not something they have actually done. It's just a way of describing how old they are. We'd say "This legend dates back to the 12th century," not "This legend has dated back to the 12th century." (This issue also rules out C, with "has dated.")

D is just not a sentence. It links a modifier to the main clause with "and," and that doesn't work.

From Ron (Manhattan Prep)

(c) and (d) are incorrect because of the word "and"; the sentence is not presenting two separate, independent facts, so "and" is inappropriate as a conjunction.

(b) and (c) are incorrect because of the tense used; "has dated" implies that this is not the case anymore. (this particular construction really only makes sense in the present tense -- or as an -ing modifier attached to a present-tense clause, since -ing modifiers adopt the tense of the clause to which they are attached.)

(e) has subject-verb disagreement ("each one of which" must be singular).

(d) uses complete sentence + comma + "and", a conjunction that should be followed by another independent clause. since "dating" isn't a verb, that second half is a fragment.

GMATNinja & GMATNinjaTwo Could you help to explain "VERBing - dating" in this problem? Why "dating" is placed after the pronoun "both"? What is being modified here?

The -ing modifier ("dating") modifies "communities" -- and the adverb "both" modifies "dating." In other words, both the Acoma community and the Hopi community date back at least a thousand years, and the word placement isn't a problem at all.

Hi GMATNinja,

Can you please explain why the tense used is incorrect here? My understanding about present perfect tense is - An action that begins in the past and continues to the present. But in the explanation given above its mentioned that '"has dated" implies that this is not the case anymore (this particular construction really only makes sense in the present tense -- or as an -ing modifier attached to a present-tense clause, since -ing modifiers adopt the tense of the clause to which they are attached.)'.

Hello hazelnut,


Although your question has already been answered, I would like to present to you how at e-GMAT we treat the modifier both dating back at least a thousand years.

We call this modifier Noun + Noun Modifier in which both = Noun and dating back at least a thousand years = Noun Modifier. Well, technically both is a pronoun. But since it refers to a noun entity, it is used in the Noun + Noun Modifier structure in the place of Noun as we see in this official sentence.

A Noun + Noun Modifier can modify any noun in the preceding clause or even the entire preceding. The modification by this modifier depends upon the context of the sentence.

In this official sentence, the Noun + Noun Modifier both dating back at least a thousand years modifies the noun The Acoma and Hopi.

For all the details, explanations, and examples (official sentences included) pertaining to the Noun + Noun Modifiers, please review our article named Noun + Noun Modifiers: The most "versatile" modifier in the following link:

https://gmatclub.com/forum/noun-noun-modifiers-the-most-versatile-modifier-137292.html


Hope this helps. :-)
Thanks.
