Agreed. I dismissed C because it didn't include the plural form of the subject

Doesn't option A,B and D change the meaning of the sentence? In these options scientists make the hormone

whereas in C and E they synthesized the hormone and between C and E

E is passive so its an easy C...

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
B) scientists had learned about making a synthetic growth hormone, they had to remove it painstakingly.
C) scientists learned how to synthesize the growth hormone, it had to be painstakingly removed
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 Before X, Y happened. X & Y both should be clause. but , here highlighted portion is a afragment, which is not making any sense

1. Verb Seq: Before X, Y happened. Thus , we need past perfect in Y to maintain this seq. Thus, A, B are out.
2. "painstakingly" is adverb. It should modify Verb "removed". Thus , A, D are out.

I dont believe a trickier SC can possibly exist :) C and D are virtually the same. I think D is better because in C , "it" after the comma should refer to scientists, not to the hormone :(

A) scientists learned how to make a synthetic growth hormone, removing it painstakingly

C) scientists learned how to synthesize the growth hormone, it had to be painstakingly removed
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

The answer is C. I was tempted by D, but than on re-reading and noticing past perfect tense in the modifiers : it had to be painstakingly removed and scientists had to remove it painstakingly , simple past have to be used in the later action.

naa , it's not the same. progressive tense + past perfect will loose to simple past + past perfect.

The problem with D is that it changes the intended meaning.
D) learning how to make a synthetic growth hormone, scientists had to remove it painstakingly

The it in second part refers to the synthetic growth hormone in first part. Now how can anyone extract synthetic growth hormone from pituitary glands. That's not possible, all you can extract is natural growth hormone, hence C is the correct answer.

For People who are still confused between C and D , the catch here is the difference between "make a synthetic growth harmone" and " synthesize the growth hormone". So as a result , in C "it" refers to the "growth harmone". In D "it" refers to the synthetic growth harmone. So meaningwise it is wrong. Scientists cannot remove a synthetic growth harmone. Hope i did my best in understanding the context.

doesen't OA,change the meaning of the sentence? Please help



Isnt C a "Run ON"?

scientist learned how to synthesize the growth hormone - an independent statement
it had to be painstakingly removed - another independent statement

both statements are not connected with conjunctions or coordinating conjunctions etc... PLease help.

Hi maadhu,
C isn't a run on you forgot the subordinating conjunction BEFORE
Before scientist learned how to synthesize the growth hormone(subordinate/dependent clause), it had to be painstakingly removed in small amounts from the pituitary glands of human cadavers.(main/independent clause)


So the structure is {sub.conjunction +dependent clause, independent clause)

Hi guys.
How do we solve the conflict of "synthesizing a hormone" and a "synthetic hormone"?
They do not mean the same thing.... Aren't we changing the meaning of the sentence?

When you sythesize something,it becomes sythentic.
but if u see the sentence as a whole,they are very closely related.

BOOKMARKED
Before scientists learned how to make a synthetic growth hormone, removing it painstakingly in small amounts from the pituitary glands of human cadavers.
The sentence is meant to say - before scientists learnt how to make synthetic growth hormones , they used to go through the painful way to extract the hormones ( growth hormones) i.e the growth hormones were removed from human cadavers

A. scientists learned how to make a synthetic growth hormone, removing it painstakingly
Sentence fragment . There is no working verb in the sentence - "before scientists learned <> , removing it <>"
the "IT" here refers to "synthetic growth hormone" , rather than "growth hormones" ( it was not the "synthetic growth hormones" that they removed from human cadavers , but was the growth hormones .


B. scientists had learned about making a synthetic growth hormone, they had to remove it painstakingly

*error in tense. The learning of making synthetic hormone , happened after they used to remove growth hormone in a painstaking way . Hence "had" in first part of sentence is incorrect.
* the "IT" in second part of the sentence refers to "synthetic growth hormone " rather than just "growth hormone" , conveying an absurd meaning that "before scientists learned to make synthetic growth hormone , they used to remove synthetic growth hormone from pituitary glands".


C. scientists learned how to synthesize the growth hormone, it had to be painstakingly removed
CORRECT : the "IT" here refers to "growth hormone" , hence conveying a correct meaning.Sentence is framed in a proper Tense.

D. learning how to make a synthetic growth hormone, scientists had to remove it painstakingly
Same issue with "IT" as in A and B.

E. learning how to synthesize the growth hormone, it have to be painstakingly removed by scientists

*Modifier error- doesn't convey who is synthesizing the growth hormone ( comma should immediately follow with the noun scientist . Which is not the case here).
Tense error - messes up the tense issue ( should be "had" instead of "have" , since this action is not happening anymore now and this happened before the scientists learned to synthesize).

You are correct. This is definitely a typo; if the intent was to refer to a "particular scientist", it should at least have been "the scientist".

Isn't 'before' modifying 'scientists' instead of 'learning'? Even in the second part there should be a reference to a person carrying out an action..... I would prefer D....

How can OA be C? There is no mention of a person carrying that action..... Also, I feel 'before' is modifying 'Scientists'.... I would have been better satisfied if the structure was more like "Before learning ___ by scientists" or "Scientists before learning ___"
Can someone clarify?
