IMO C

In cold-water habitats, certain invertebrates and fish convert starches into complex carbohydrates called glycerols, in effect manufacturing its own antifreeze.
(A) in effect manufacturing its own antifreeze --> its here is not suitable because the mentioned objects are vertebrates and fish, so can't be it
(B) effectively manufacturing antifreeze of its own --> the same error
(C) in effect manufacturing their own antifreeze --> in effect correctly plays the role of an adv, and them are better than it --> the best
(D) so that they manufacture their own antifreeze --> they here play the role of a subject of the new clause but it is not clearly modified for which Noun: carbonhydrates, glycerols, starches or vertebrates and fish ???. Finally, using clause here is more complex than using participle phrase as (A), (B) and (C)
(E) thus the manufacture of its own antifreeze --> wordy and wrong meaning, etc

I can't understand the meaning of this sentence. My question is: Is "manufacturing ... antifreeze" the result of action "convert" done by invertebrates and fish? If so, then why don't we have structure: "Main clause, Verb-ing" to express the result of the main clause?

Yes you are right that conversion of starches leads to manufacturing of antifreeze.
But in GMAT we have to find the best option out of the 5 options presented to us. This does not mean that the correct option is the best available option in the whole world :)


Options A, B and E can be eliminated because of the usage of singular pronoun its with plural noun invertebrates and fish.

The only contenders are C and D.

The problem with D is that, they is ambiguous here. THEY might refer to invertebrates and fish or carbohydrates. Moreover (D) somehow changes the intended meaning of the sentence.

D says: Invertebrates do X so that they can cause Y.
Here focus is more on Y. Invertebrates are doing X just to achieve Y.

C says: Invertebrates do X, causing Y.
So here Y implicitly gets done when Invertebrates do X.
This is the intended meaning.

Note: This question has already been discussed in the following thread:

Please search properly before posting a new question.

'certain invertebrates and fish' is a plural noun and hence requires plural verb 'their'. A, B and E are out.

(C) in effect manufacturing their own antifreeze. Correct option as it mentions the intended meaning.

(D) so that they manufacture their own antifreeze. 'So that' depicts that something is done intentionally by the organisms, but this is not the case. Something is done without any intentions. Hence this is a wrong choice

We have 3:2 split here. 'Its' is not the correct pronoun to be used here. Eliminate A, B and E

Between C and D:
(C) in effect manufacturing their own antifreeze - Correct. Correctly modifies the action described in the previous clause

(D) so that they manufacture their own antifreeze - Incorrect. Meaning error. This option suggests that the invertebrates and fish intentionally converted starch to carbohydrates to manufacture their own antifreeze.

Answer: C

Meaning : In cold water habitats, some invertebrates and fish convert starches into glycerols to protect themselves from freezing.

Mistake analysis : invertebrates and fish are plural so there has to be plural pronoun. So, A,B and C are eliminated.

D) so that indicates purpose or in order that, so here for the conversion purpose they manufacture their own antifreeze is wrong.

It is due to the cold effect they manufacture their own antifreeze.

So Option C is correct.

A, B, and E are out - SVA error

its -- invertebrates and fish

C - corrects that SVA
D - changes the meaning (D sounds like converting starches enables them to make antifreeze,
While the intended meaning is converted starches is their antifreeze)

Hi
"D" seemed correct answer to me, but I understand that D is actually changes the meaning.

However I am still confused how answer choice C is grammatically correct?
"in effect manufacturing their own antifreeze" is it prepositional phrase? Or present participial?
Someone in the above explained that "in effect" is adverb, in that case which word, phrase or clause "in effect" modifys?

I guess I have some grammatical gap

EducationAisle,

Can you throw some light on options C and D.

What is wrong with option D?
Invertebrates and Fish convert.... so that they manufacture their own antifreeze.
This sentence too makes sense.

Yeah, as some of the explanations above suggest, the original sentence seems to suggest that manufacturing of antifreeze happens inadvertently (unconsciously).

D changes the meaning and introduces explicit "intent".

EducationAisle,

We keep the meaning of the original sentence in mind while evaluating the options?

Thanks

I understand there are varied opinions on this, but my opinion is that if the meaning coming out of the original sentence is logical, we should generally try to choose an option that sticks to that meaning.

Hello krndatta,

We hope this finds you well.

To answer your query, we would like to back @EducationAisle; if the meaning conveyed by Option A is logical, we should consider it the intended meaning; only select an answer choice that changes the meaning of Option A if all other options have grammatical errors.

We hope this helps.
All the best!
