C is correct.
This option,infact is most clear and concise.
It clearly refers to the harmone.

C has to be wrong. It changes the meaning, "make a synthetic growth hormone" does not mean "synthesize the growth harmone"

I know the OA is C but I think its WRONG! AGREE???????

Before scientists learned how to make a synthetic growth hormone, removing it painstakingly in small amounts from the pituitary glands of human cadavers.
A. scientists learned how to make a synthetic growth hormone, removing it painstakingly => lack of main verb and object in 2nd Noun phrase
B. scientists had learned about making a synthetic growth hormone, they had to remove it painstakingly (in small amount...) => make nonsense
C. scientist learned how to synthesize the growth hormone, it had to be painstakingly removed => More logically with the remain non-underline. Correct
D. learning how to make a synthetic growth hormone, scientists had to remove it painstakingly => Same reason as B
E. Learning how to synthesize the growth hormone, it have to be painstakingly removed by scientists => the interfere of by scientists make the remain illogical, moreover, the first phrase should modify scientists right after it

It comes under conciseness. to make a synthetic... can be expressed more stlyistically by making it synthesize


but, there is a word meaning difference betwen synthetic (which means artificial, or not natural) and synthesize (which means to form a whole). just this difference mademe choose B. else C obviously is more concise.
i dont think we can subordinate meaning to concision.

Any thoughts?



I agree that there is a change of meaning in c...

But b has grammatical error :
Before scientists had learned about making a synthetic growth hormone, they had to remove it painstakingly in small amounts from the pituitary glands of human cadavers.


Here we find a mis use of the past perfect tense...

Hence, I feel that whenever we have confusion with grammar and meaning, we should first prefer to correct the grammar and then meaning.
Hence C here is the best choice..

This question tests the Past Perfect Tense.
"B" is incorrect because it uses had twice. This does not make sense in terms of event sequence.
"C" is correct because it uses simple Past in the first Clause and Past Perfect - had construction - to indicate the sequence of events.
1) First they had to Painstakingly extracted the hormone
2) Later they were able to create it synthetically.

I was reading the Manhattan Post regarding this Question. According to the Instructors on that Forum "the had to be removed" construction is not in Past Perfect Tense. I would like to ask for a break down of each individual answer choice.

My answer was D, though "it" was not referring to hormone but that was the best choice available
as C had the word scientist and not scientists which makes it to point to a particular scientist ?

Its C for sure, why id D wrong ?

Option D: implies that scientists extracted synthetic growth hormone, not naturally occurring growth hormone, from human bodies. and which changes the original meaning.

Agree with C.

You have to also look at "make a synthetic growth hormone" vs "synthesize the growth hormone " . You cannot make a synthetic hormone; you can only synthesize it.

Hope this helps.

Haha this is a classic modifier trap on the GMAT.

This makes it look like D is the answer because it looks too simple to be a DANGLING MODIFIER ANSWER. But D has a two major problems, I believe.

First: How to make synthetic growth horomone is wordy. how to synthesize is BETTER.
Second: Remove it painstakingly? What is painstakingly modifying? It should modify remove right? But it looks like its modifying IT, which in turn refers to the hormone.

Actually I feel the Second reason is more applicable to get the 3-2 split in this problem. The reason is because the first is a not a MAKE OR BREAK RULE. WORDY is just a preference.

And you were caught in the trap :) .

Verb modifiers (or I should say Adverbial modifiers) do not need to be adjacent to the verb they are modifying. Only noun modifiers need to be adjacent to the nouns they are modifying :) .

The minister addressed her congregation solemnly => Here the adverb solemnly modifies the verb addressed.

the scientists should learn how to synthesize growth hormone, not how to make synthetic growth hormone. That why choice D is incorrect.

IMO Answer:- D.
In the original sentence, "how to make a synthetic growth hormone" to make synthetic growth hormone is grammatically correct and can be used in the answer choices.
Based on our scientific knowledge, we can deduce out whether to adjust the sentence as "to synthesize growth hormone".

@shikhar, could you please confirm whether "Before" is underlined as well?

Agree with you in the original sentence, how to make synthetic growth hormone is grammatically correct, but the meaning has a problem. So, that why choice D is incorrect.

The chief problem in this topic is to succumb to the tempting assumption that scientists removed the natural hormone, before they could synthesize it. However, the text does not specify this. After all the text itself is a fragment with only an introductory subordinate clause but without a main clause

This is the reason that choices B, D and E fall flat, which categorically state that the scientists removed the hormone. In addition, in D, since the pronoun ‘it’ refers to ‘the synthetic growth hormone’ you have the logical question of how anyone could have removed a synthetic hormone, even before knowing how to make it or synthesize it.

C avoids the first pitfall by tactfully switching over to a passive voice, leaving the question of who removed the hormone wide open. In addition and aptly, the pronoun ‘it’ in C simply refers to a growth hormone and not a synthetic growth hormone.

Something else jumped out on me on D... Is it possible that there's a misplaced modifier, i.e. "Scientists had to remove it painstakingly in small amounts" vs "Scientists had to painstakingly remove it in small amounts"?

C) scientists learned how to synthesize the growth hormone, it had to be painstakingly removed - part marked in RED changes the meaning of the sentence. Scientists did not learn to synthesize the hramone itself, they just learned how to make the synthetic harmone.


Who is to say that the meaning of the sentence changes here? Wouldn't marking option A itself wrong somehow mean the sentence does not have a fixed meaning? It could be synthetic or synthesize.. I'd go with option C.
