Will go for C.
A) scientists learned how to make a synthetic growth hormone, removing it painstakingly B) scientists had learned about making a synthetic growth hormone, they had to remove it painstakingly. ( Both the Phrases in Past perfect tense looks no good ) C) scientists learned how to synthesize the growth hormone, it had to be painstakingly removed ( Will go for this) Talking about two action in the past. So i took it. D) learning how to make a synthetic growth hormone, scientists had to remove it painstakingly E) learning how to synthesize the growth hormone, it had to be painstakingly removed by scientists ( passive voice)

A) scientists learned how to make a synthetic growth hormone, removing it painstakingly - Wrong way to phrase the sentence. B) scientists had learned about making a synthetic growth hormone, they had to remove it painstakingly - Use of "had" 2 times is wrong. 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. D) learning how to make a synthetic growth hormone, scientists had to remove it painstakingly - correct and only remaining answer. E) learning how to synthesize the growth hormone, it had to be painstakingly removed by scientists - Same as C.

Right catch
C and D gramatically both correct, but C changes the intent.
'to make synthetic X' and 'to synthesize X' are different.

OA is C
as everybody has said, C and D are really close. That's why the question,IMO, is hard.
D) Before learning how to make a synthetic growth hormone, scientists had to remove it painstakingly in small amounts from the pituitary glands of human cadavers.
The main problem with D is that "it" refers to "synthetic growth hormone" and not only to synthetic growth hormone. Pronouns refer to the adjectives-noun. In addition, the scientist did not remove the growth hormone, so option C correctly uses the passive voice.

I pick C. For D, the sentence implies that scientists extracted synthetic growth hormone, not naturally occurring growth hormone, from human bodies. This, I think, changes the meaning.
The only thing strange about C is the word "the" preceding "growth hormone." I suppose that if the sentence is referring to a specific growth hormone, then it's okay.
But isn't "scientists" plural in C? Maybe it was edited later. _________________

C.
A. scientists learned how to make a synthetic growth hormone, removing it painstakingly Sentence fragment. Referent of 'it' is synthetic growth hormone, when 'it' should be referring to growth hormone.
B. scientists had learned about making a synthetic growth hormone, they had to remove it painstakingly Referent of 'it' is synthetic growth hormone, when 'it' should be referring to growth hormone.
C. scientist learned how to synthesize the growth hormone, it had to be painstakingly removed Pronoun 'it' is sensible as it refers to the growth hormone.
D. learning how to make a synthetic growth hormone, scientists had to remove it painstakingly Referent of 'it' is synthetic growth hormone, when 'it' should be referring to growth hormone.

OA will follow
This is really a typical sc which test profound meaning. C and D are both correct in grammar but have different meanings. D is illogical jerk because it means that: before scientists learn how to synthesize a hormone, they had to remove it (hormone) from nature (which is one of a step in the hormone synthetic process) --> so if hormone is already there, scientists dont have to synthesize it. C is rational because it means: before scientists learn to synthesize a hormone, hormone had to be removed from nature (because people have not synthesise it yet so they have to use hormone from nature resource). --> that's the meaning of C. this idea has come up with me when i've browsed this link, found it is very useful to read Ron's explanation. http://www.manhattangmat.com/forums/bef ... -t637.html _________________

IMO C
A,B,D can be ruled out because it uses the term "A synthetic growth hormone " and uses "it " later on , implying that the synthetic growth hormone had to be extracted , which makes no sense .

Between C and E - which one is correct , please provide proper explanation
IMO D. Present participle modifier issue here. D correctly addresses is it by placing "scientists" at the beginning of 2nd clause.
C- no clear referent for pronoun "it" B- learned about making is awkward. A- no clear referent for pronoun "it"

I went through the answers and realized my above post is wrong. D is obviously incorrect because of meanining issues. C wins.

I will proide OA later after 8-10 posts.
A very nice question on pronouns. C wins. All other options have synthetic hormone as the referent for "it". Synthetic hormones cannot be removed from human cadavers.

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.
