GMATNinja, in option D, " it expands..." refers to the slime which distorts the meaning. It should refer back to hagfish as it does in option E. Is this line of reasoning incorrect?
It doesn't make sense for "it" to refer to "hagfish" -- it's not the
hagfish that expands several hundred times as it absorbs seawater. Rather, it's the
slime that expands several hundred times as it absorbs seawater.
Remember, as explained in
this post, there is nothing special about the meaning in choice (A)!
GMATNinjaIMHO, "It"
can refer back to hagfish.
"...,
it expands several hundred times as it absorbs seawater,
forming a
slime ball....", as the antecedent of
"it" is performing the action of
"forming a slime ball". Request you to please let me know if there's a flaw in my understanding.
Thanks.
The word "although" is the key here.
As explained in
this post, we're looking for a logical contrast between the two clauses. If the "it" refers to "hagfish" in (D), then we'd have this:
"Although the slime {...} is small in quantity, [the hagfish] expands several hundred times as it absorbs seawater."
But in that case, the "although" doesn't really make sense. There's no logical contrast between (1) the
slime being small in quantity and (2) the
hagfish expanding several hundred times as it absorbs seawater.
Also, the "forming" part doesn't make as much sense if "hagfish" is the thing that's absorbing seawater and expanding:
- We're told that the threatened hagfish excretes a small quantity of slime.
- If it's the hagfish that's absorbing seawater and expanding, then the slime is NOT absorbing water and expanding -- it's just sitting out there in the ocean as a small quantity of slime.
- Does that mean that the hagfish (1) excretes a small quantity of slime that floats around uselessly in the ocean and then (2) starts forming some other new slime ball (that has nothing to do with the small quantity of slime already excreted)? What exactly does the expanding of the hagfish have to do with the formation of the slime ball? We could come up with some theories, but, at best, the meaning is unclear if we go with that interpretation.
It makes much more sense to assume that the slime itself forms a slime ball as it absorbs seawater and expands. The structure of (D) lends itself to this logical interpretation: the reader naturally expects the pronoun (the subject of second clause) to refer back to the subject of the first clause, so the intended meaning is perfectly clear.
I hope that helps!
