Anasazi settlements

IMO B
connected by a complex regional system of roads. is modifying the structures, so "were" is not necessary

The main subject is the settlements and the phrase set off between the two commas is modifying the structures and not the settlements. The answer should be B. I usually test the correctness by removing the non essential modifiers and see if the sentence makes sense. If what tohellandback is saying about the modifier and the modified are correct than D would have been a correct choice.

IMO B....My reasons for kicking out each choice is as below:

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
we need "and" before were to make the sentence grammatically correct...

settlements were built...and were connected.

(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
had is past perfect.....we do not need past perfect.

(D) of more than 75 carefully engineered structures of up to 600 rooms and with each
and signifies parallelism....there is nothing to parallel "with each"

(E) of more than 75 carefully engineered structures of up to 600 rooms each had been
had is past perfect.....we do not need past perfect.

Actually, I think the past perfect is fine here. However, choices C and E could be eliminated because 'each' seems to be modifying the rooms here.

Can you please tell why past perfect is correct ?

It seems that 'had been' may be okay here since everything wasn't connected at once, but were connected over some unspecified period of time, which the past perfect usually refers to.

IMO...had is used when we are sure that one activity got completed before another one...

here the other activity is built....which in my opinion was going on in parallel with connection.....

Connection with roads in my opinion cannot precede....building...

Ah, okay. Thanks!

B.

any comments on whether "of more than" usage is right here? sounds wrong to me, which would immediately eliminate CDE.

Can you please elaborate it a bit...why "of more than" is wrong and "with more than" right ?

Final solution at one place:

Important: The purpose of this post (and all the other posts by me) is to give a complete solution to all GMAT-Prep Verbal questions at one place. Sometimes students have to wade through dozens of posts to get to the final answer. My posts will give one complete and crisp solution required to arrive at the correct answer by eliminating the wrong ones. Some of the content in these posts may have been taken from various other sources (discussion forums).

In this construction, ‘scale of’ is the wrong idiom. ‘Scale of’ is correctly used in constructions such as: ‘on a scale of 0-10’. This eliminates C, D, and E.

In A, if we remove the nonessential part between the commas, we are left with:

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

In A, we can’t use ‘were’ … ‘were’ without a connecting word (such as ‘and / or / but / that etc. depending upon the meaning’). In this sentence, the ‘structures’ were ‘connected’, so we surely need some connector (preferably ‘that’) between ‘structures’ and ‘were’. Or else, A becomes a run-on sentence. 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. UGH!

Similarly, E is a run-on sentence.

In B, if we remove the nonessential part between the commas, we are left with:

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

In the sentence above, the last part is a non-essential modifier. Perfect.

In C, D, and E, ‘scale of’ is the wrong idiom.
Also, in C, we can’t use the past perfect ('had been') as the events don’t have a time lag.
