Re: The Anasazi settlements at Chaco Canyon were built

choice D is illogical because it means ... that each individual structure had its own system of roads!


^^ yes; nice observation.

the same idea can also be used to eliminate C, too. (comma + "each..." would also refer to the preceding plural noun—so, choice C is ALSO implying that each individual structure had its own road system.)

Hi Ron, choice C, comma + each refer to the preceding plural noun, there is a plural noun "rooms" right before the comma, does this "each" refer to rooms? Well even each modifies rooms, the sentences is incorrect.
Thanks

^^ you're correct that the modifier could also be read that way. but that interpretation is also nonsense, so, that choice is still wrong.

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).



Dear Ron Sir,

First and foremost, please allow me to thank you for your marvelous explanations! -- I don't know how to thank you enough, since you turn the preparation of GMAT into a great fun of exploring intelligence.

Can I confirm whether my following understanding is right?

The structure that exists in (b) is same as the one used in "Astronomers have detected more than 80 massive planets, most of them at least as large as Jupiter, circling other stars." and as the one applied in "Lina's sunbird has a brilliant orange patch, bordered with red tufts, in the centers of its breast.".

Therefore, we have such a structure: noun + ","+ adjective nonessential modifier phrase 1 + "," + adjective nonessential modifier phrase 2 (no "and" between the two modifiers), when the two adjective modifiers have equal priorities, right?

And does the boldface part from "Paleontologist Stephen Jay Gould has argued that many biological traits are not the products of natural selection, favored..." follow the structure "noun+adj1+comma+adj2" as well?

Thanks a lot!

^^ yes, choice B is essentially the same type of structure as these examples.

^^ no, because "the products favored..." doesn't make sense.
in this case, the second modifier makes sense as a description of the entire phrase "the products of natural selection".
