I am not clear about the use of scaled of and scaled with :?


"Scale of " is used to compare the sizes of two objects (generally a copy with the original).

This drawing has been made in a scale of 1 to 10..... implies 1 cm on the drawing is equivalent to 10 cm real distance.

Another usage could be as follows:

How would you rate my answer on a scale of 1 to 10? .... implies you have to evaluate my answer with a max / min possible values of 1/10.

However in the subject question, the word " scale" is used in a different way - to convey the meaning "size". Therefore "scale of" is not correct.
(The preposition "with" has no bearing with the word "scale" whatsoever.)

Hi there, quick question regarding the nonessential modifiers. Are we allowed to have more than one in a sentence like in this case. And, can they be prepositions (with...of...?) Thanks!

The final modifier doesn't modify "rooms" for three reasons: 1) it doesn't touch either noun ("each" is not a noun here), 2) we have two modifiers on top of one another, so we have to read for meaning, and 3) the intervening modifier is set off with commas, making it an aside that we can skip over structurally.

Also, notice that none of the answers do anything to make the meaning clearer. In fact, C-E seem to make the rooms connected. So we can't use this issue to narrow things down very well. Besides, if the rooms were connected, that wouldn't stop the sentence from working.

Dear Smileyface123,

I'm happy to respond. :-)

The short answer is: YES. Yes, we can have 2 or 3 or maybe even 4 non-essential prepositional phrase modifiers in a row. At some point, the flow of the sentence becomes unclear if there are too many, but we won't see that case on the GMAT. Also, notice that prepositional phrases are short, usually 2-3 words. Other noun modifiers (participial phrases, modifying clauses, etc.) are much longer, but if those are non-essential, there would likely be not more than one interrupting the flow of the sentence and most often these are set off by commas, as were the pair of prepositional phrases in this sentence.

Does all this make sense?
Mike :-)

Could anyone please post the official answer for the question? Why is C incorrect? What is connected by roads?

Dear vad3tha,
I'm happy to respond. First of all, the OA is posted for this question already. When you see this:
Attachment:
OA Spoiler Bar.JPG

the gray spoiler bar at the bottom of a question at the head of a post: that's precisely where the OA is. You simply click on "[Reveal]" and you can view the OA.

Now, why is (C) incorrect? Well, first of all, the word "of" is idiomatically incorrect, and this is part of what makes (C), (D), and (E) incorrect. This sentence, by itself, is correct:
The Anasazi settlements at Chaco Canyon were built on a spectacular scale.
If we want to indicate more detail, we add detail to the settlements, not to the word "scale" itself.
The Anasazi settlements at Chaco Canyon were built on a spectacular scale with more than 75 carefully engineered structures.
Perfectly correct. The "with" phrases are modifying "settlements."
The Anasazi settlements at Chaco Canyon were built on a spectacular scale of more than 75 carefully engineered structures.
In this version, the "of" phrase illogically modifies "scale", telling us (??) what kind of scale?? This makes no sense. The choices that use "of" here are incorrect.

Even if choice (C) had the correct word "with" instead of "of", the ending is still awkward, wordy, and not direct.
Version (B) = ... 75 carefully engineered structures, of up to 600 rooms each, connected by a complex regional system of roads.
Version (C) = ... 75 carefully engineered structures, of up to 600 rooms, each that had been connected by a complex regional system of roads
Use of the past perfect tense is illogical --- had been. Also, this is a wordy and awkward way to express this idea. Also, (C) subtly changes the meaning. In choices (A) & (B), it's clear that the "structures" were "connected by ... roads." Choice (C) changes the meaning, illogically suggesting that each room has its own road!! Thus, if there were a structure with 600 rooms, this structure would have 600 road coming into it? The ancient Anasazi were not building complex highway interchange ramps!! That is 100% illogical, as well as a very different meaning from what is expressed clearly in the prompt.

For all these reasons, (C) is irredeemably incorrect.

Does all this make sense?
Mike :-)


Hi GMAT exports,

I am confused about the sentence structure of this question. If the modifiers, "of up to 600 rooms each" and "connected by a complex regional system of roads" both modify "structure", why there is no conjunction word "and". Should the absence of "and" be a parallelism error for choice B? Can someone please let me know if "and" is always required in a list?

Dear bubblehead0922,

I'm happy to respond. :-)

Here is version (B), the OA:
The Anasazi settlements at Chaco Canyon were built on a spectacular scale with more than 75 carefully engineered structures, of up to 600 rooms each, connected by a complex regional system of roads.
This is 100% correct as is.

A list is a series of discrete elements. For a list structure, the elements are in parallel and of course we typically would have "and" or "or" joining the elements. That is not what is happening in this sentence. This sentence did not attempt to create a list and do the job poorly. Instead, it was doing something else.

There are several other patterns in language beside listing. One pattern is the parenthetical remark. A parenthetical remark, sometimes called an "aside," is an extra piece of information that the speaker throws in. It typically disrupts the flow of the sentence, and often is set off on each side either by commas or by dashes (em-dashes).

In this sentence, the parenthetical remark is "of up to 600 rooms each." Notice that we could remove this remark and the sentence would still be perfectly fine. The author could have chosen to write this as the following:
The Anasazi settlements at Chaco Canyon were built on a spectacular scale with more than 75 carefully engineered structures—of up to 600 rooms each—connected by a complex regional system of roads.
That version sets the parenthetical remark off in em-dashes. This version is not as good: we set off a parenthetical remark in em-dashes when it's logically further from the sentence, a real interruption to the flow of thought. Here, the parenthetical remark is still very much on topic, so setting it off between a pair of commas is fine.

This is NOT parallelism. This is a different way of positioning a pair of complex modifiers.

My friend, there's no complete list anywhere of all the ways that language can be used. It's impossible to get to SC mastery by learning some mythical "complete set" of rules. You have to learn the "feel" of the language, and the only way to develop that is to cultivate a habit of reading. See:
How to Improve Your GMAT Verbal Score

Does all this make sense?
Mike :-)

My Answer B (Awaiting OA)

The Anasazi settlements at Chaco Canyon were built on a spectacular scale with more than 75 carefully engineered structures, of up to 600 rooms each, were connected by a complex regional system of roads.

A. with more than 75 carefully engineered structures, of up to 600 rooms each, were -"were" is not required. we just need to say that "Canyon had more than 75 structures connected by system of roads."
B. with more than 75 carefully engineered structures, of up to 600 rooms each, -Correct
C. of more than 75 carefully engineered structures of up to 600 rooms, each that had been -"spectacular scale of more than 75 structures" doesn't seem correct. The Chaco Canyon was built on a very large scale consisting of more than 75 structures. Thus, the opening words of this option aren't correct. Also, this option is depicting that each of 600 rooms were interconnected by a system of roads; this thought is nonsensical.
D. of more than 75 carefully engineered structures of up to 600 rooms and with each -Opening words of this option are wrong as per the explanation in option C.
E. of more than 75 carefully engineered structures of up to 600 rooms each had been -Opening words of this option are wrong as per the explanation in option C.

The Anasazi settlements at Chaco Canyon were built on a spectacular scale with more than 75 carefully engineered structures, of up to 600 rooms each, were connected by a complex regional system of roads.

A. with more than 75 carefully engineered structures, of up to 600 rooms each, were --- it is clear that this simple sentence is riddled with two verbs namely 'were built' and 'were connected' without a proper conjugation. This is double verbing and out

B. with more than 75 carefully engineered structures, of up to 600 rooms each, ---Now that the double verbing is gone, let us come back to this a while later.

C. of more than 75 carefully engineered structures of up to 600 rooms, each that had been -- it is absurd to say that the 75 structures had been interconnected before they were constructed. Therefore this is out.

D. of more than 75 carefully engineered structures of up to 600 rooms and with each --- comma plus with each is a phrase. This not parallel with the previous IC and We may call it either unparallel or the second part a fragment

E. of more than 75 carefully engineered structures of up to 600 rooms each had been-- here is a fused sentence, the first with were constructed, and the second with had been connected( we already know 'had been' is wrong)

Now let's go back to B, the structure is a simple sentence with an underlined 'comma plus ed modifier' at the end. perfect foil

Firstly, thank you for your explanation, I really appriciate that. But i have question ralted to Subgroup question.
For this question, the OG explain in answer C that " The comma preceding each make each a subject, but is has no verb, since that is the subject of had been connected". BUt what if it could be the SUBGROUP MODIFIER as the sentence following in Manhattan:
This model explains all known subatomic particles, SOME only recently discovered.
or "This model explains all known subatomic particles, SOME OF THEM only recently discovered"
I acknowledge that answer C makes no sense but the official explanation make me confused.
Please clarify! :)

Yeah... I have no idea what the OG is talking about there. Keep in mind that the people who wrote the OG explanations are NOT the same people that wrote the questions. In most cases, the OG questions were produced years -- or even decades -- before they appeared publicly in the OGs, so whoever writes the explanations often doesn't know what the question-writer intended. And sometimes you just get incoherent messes as a result.

I think you might also be asking whether it's possible to have a subgroup modifier -- or an absolute phrase -- beginning with "each." Sure, that's entirely possible in theory, it's just that the meaning doesn't make sense in this case. Here's an example that might help: https://gmatclub.com/forum/qotd-naked-m ... 39472.html.

But don't worry too much about those OG explanations if you don't find them helpful. Some of them are awesome. Others are putrid. :|

Ron's answer

choice a is a run-on - it tries to have two main verbs without using any sort of subordinating element. if you take out modifiers, adjectives, etc., you're left with the following: the settlements were built with structures were connected. that's bad.

choice b is correct: it uses a nonessential modifier set off by commas ('of up to 600 rooms each'), which, if eliminated, yields the intact and legitimate sentence ...carefully engineered structures, connected by... (with another nonessential modifier).

choice c:
- 'scale of' doesn't make sense
- you can't say 'each that had...' (can't follow 'each' with a relative pronoun - if you're going to use a relative pronoun, it has to come directly after the thing it's trying to modify)
- no justification for using the past perfect ('had been') - that verb, if there's a verb there at all, should be in the simple past (the same tense as everything else in the sentence, because everything described in the sentence is contemporaneous)
- it doesn't make sense to use 'each' AFTER the comma, because it's not true that each structure was connected with a road system. instead, the road system connected all of the structures with each other, which is nowhere close to the same thing. (having 'each' BEFORE the comma makes sense, because it's actually true that each of the structures comprised up to 600 rooms.)
analogy:
the USA comprises 50 states, each of which is united by a federal government --> wrong (the implication is that each state has its own federal government)
the USA comprises 50 states, all of which are united by a federal government --> correct
the USA comprises 50 states, (all) united by a federal government --> correct, whether you have 'all' or not

choice d:
- 'scale of' doesn't make sense
- the use of AND sets up ostensible parallelism, but the two structures given aren't parallel (one starts with of and the other with with)

choice e is also a run-on sentence (you'll see this if you reduce it to its 'skeleton', a la choice a)
