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) scale,with more than 75 carefully engineered structures, of up to 600 rooms each, were

(B) scale,with more than 75 carefully engineered structures, of up to 600 rooms each,

(C) of more than 75 carefully engineered structures of up to 600 rooms, each that had been

(D) of more than 75 carefully engineered structures of up to 600 rooms and with each

(E) of more than 75 carefully engineered structures of up to 600 rooms,each had been

答案选B,这句话的意思说的是structure connected by而不是rooms connected by吗？还有b选项的with引导的句子修饰的是built吗？这道题做了好几次了，每次都错，分析的时候通过哪个点排除比较好呢

让大神ron来解析吧

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)

Hi Ron,
In choice B, two modifiers are not connected by and. is that ok?
I was expecting something like '..of up to 600 rooms each and conneted...'
Can you please comment?
Thanks in advance,

Ron:
nope, that would be incorrect.

the current form is the correct modifier, because it's modifying the 75 structures (of up to 600 rooms each).

if you added "and", then that would lock the following word, connected, into a parallel structure.
the problem is that "connected" is a past participle, and the only other word in the sentence that could be parallel to it is the past participle "built".

so, by adding "and", you'd be unwittingly creating the following parallel structure:

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, and
connected by a complex regional system of roads.

this is wrong, since it implies that the settlements themselves were connected by a system of roads. it's the structures that were thus connected.

Ron:

nope. you have to think about which things are describing which other things.

* it's possible that both modifiers are describing the same noun, as in the example above. in that case, well, you have to put one of them before the other one (since you can't draw a sentence that looks like a probability tree), so you get the kind of structure that exists in (b).

* it's also possible that the second modifier describes something in the first modifier.
e.g.,
In the fourth lane is Tony Cardinale, the son of Vinny and Alessandra Cardinale, two former Olympic swimmers from Italy.
in this case, two former... is describing vinny and alessandra, not tony.

概括下，大神说of up to 600 rooms each,和connected by a complex regional system of roads都是修饰structures

structures每个有多达600房间，而structures由 a complex regional system of roads 连通起来
