This answer choice solves the ambiguity of the original sentence by changing the main verb comprises to the unconjugated verb comprising (and thus turning almost the entire underlined section into a modifier) and by changing the unconjugated verb supporting to the conjugated verb supports (making it the main verb).

If we look at the sentence without the new modifier, it makes sense:

Ecuador's extraordinary topographical diversity , ... , supports an equally astounding diversity of wildlife species.

With A you have a problem. It is ambigous: What does "supporting an equally astounding diversity of wildlife species" refer to?

To understand the statement properly break the sentence into clauses.

Ecuador's extraordinary topographical diversity,
comprising snow-capped peaks
reaching an altitude of more than 20,000 feet
and
rain-forest ravines
that descend steeply toward the Amazon basin,
supports an equally astounding diversity of wildlife species.
The bold face parts are modifiers that explain the snow capped peaks and rain forests respectively.
The first is verb+ing modifier and in second 'that' refers back to rain forest ravines and the following clause with that as a subject explains the forests.

Of course B is the correct choice, but I would have felt more comfortable with: "diversity, comprising snow-capped peaks that reach an altitude of more than 20,000 feet and rain-forest ravines that descend steeply toward..." for the sake of parallelism.

Totally agree with you. That's why I eliminated B and chose A instead.
Anyway, as explained above by expert Daagh, B is preferred for rightly stressing main idea of the sentence.
Nonetheless, I still feel that this split is quite subtle... just my opinion.

The main idea is properly reflected in B, but I wonder how can --supports " an equally" ........ can refer to the absolute phrase used to modify the subject of the sentence.

To make my point clear - how can " an equally" refer to the absolute phrase "comprising.....basin"

Hi, in my opinion, "an equally" and phrase "comprising snow-capped peaks..." have no relation in this sentence.

Ecuador's extraordinary topographical diversity, comprising snow-capped peaks reaching an altitude of more than 20,000 feet and rain-forest ravines that descend steeply toward the Amazon basin, supports an equally astounding diversity of wildlife species.

blue colored: main clause
pink colored: V-ing modifier modifying subject of the sentence - "Ecuador's extraordinary topographical diversity". That modifier describes how diverse Ecuador's extraordinary topography is.

The noun phrase "equally astounding diversity of wildlife species" plays the role of sentence's object. In that noun phrase, adverb "equally" modify adjective "astounding".

As you can see, there is no relation between these two parts.

As you can see

This question sucked my time.
Was oscillating between A and B.

Finally chose B, as Daagh pointed out that stress should be on "equally astounding diversity of wildlife species". Option A stresses on what topological diversity comprises of.

A. diversity comprises snow-capped peaks reaching an altitude of more than 20,000 feet and rain-forest ravines descending steeply toward the Amazon basin, supporting

B. diversity, comprising snow-capped peaks reaching an altitude of more than 20,000 feet and rain-forest ravines that descend steeply toward the Amazon basin, supports

E. diversity comprises snow-capped peaks reaching an altitude of more than 20,000 feet and rain-forest ravines descending steeply toward the Amazon basin, is supporting


This took question really took some grit to solve- it is very misleading, but the idea that the sentence is trying to express is that Ecuador's topographical "diversity" is what supports "an equally, etc."

Also the usage of that in B makes the sentence much clearer. C is a trap answer because many readers read from left to right and GMAC knows that this bait test takers to eliminate A, B, D E -

Can someone explains why "comma+supporting" will wrongly modifies the other noun, doesn't (comma + Ving) modifies preceding clause OR the main Subject ?

Is A wrong because "comma+supporting" can modify either preceding clause OR main subject thus makes the meaning ambiguous?
(Main Subject: Ecuador's extraordinary topographical diversity)

But why Economics's explanation says "comma+supporting" will wrongly modifies snow-capped peaks and rain-forest ravines.

Hello soodia - Please find the explanation as per below:

D. diversity, comprising snow-capped peaks reaching an altitude of more than 20,000 feet and rain-forest ravines and descending steeply toward the Amazon basin, supports

Problem with D ==> the usage of "and descending steeply toward the Amazon basin" means that this is the third aspect of diversity and in this case it is incorrect as there are only two points that are part of the diversity discussed here and those two parts are - 'snow-capped peaks' and 'rain-forest' the part - and descending steeply toward the Amazon basin should be describing the 'rain-forest ravines'. Adding 'and' changes the meaning.

B. diversity, comprising snow-capped peaks reaching an altitude of more than 20,000 feet and rain-forest ravines that descend steeply toward the Amazon basin, supports

B does not have parallelism issue:

Diversity - Comprising:

==> snow-capped peaks peaks reaching an altitude of more than 20,000 feet and

==> rain-forest ravines that descend steeply toward the Amazon basin

Both 'now-capped peaks' and 'rain-forest ravines' are parallel.

Hope this helps - please do let me know in case you have any specific question. Thanks
