C

Hi chetan2u,
How do we know that it was "isolation of Insulin" and not "insulin" which was a significant medical breakthrough since, Insulin is also a medical term.
also in B, antecedent of "It" is not clear. Can we say for sure that 'it' is referring to real story?

Perhaps the most significant medical breakthrough of the twenties, the real story behind the isolation of insulin was not revealed for over fifty years .

A)Perhaps the most significant medical breakthrough of the twenties, the real story behind the isolation of insulin was not revealed for over fifty years.
The phrase Perhaps the most significant medical breakthrough of the twenties must modify isolation of insulin. It makes no sense for this phrase to modify the real story.
B)The real story behind the isolation of insulin was not revealed for over fifty years, even though it was perhaps the most significant medical breakthrough of the twenties.
This sentence can be rephrased as even though it was perhaps the most significant medical breakthrough of the twenties,The real story behind the isolation of insulin was not revealed for over fifty years. Here again there is modifier error as in choice A. The most significant medical breakthrough was isolation of insulin and the the real story.
C)Although the isolation of insulin was perhaps the most significant medical breakthrough of the twenties, the real story behind it was not revealed for over fifty years.
Correct
D)The real story behind the isolation of insulin was not revealed for over fifty years, although insulin was perhaps the most significant medical breakthrough of the twenties.
Modifier error. Insulin was not the most significant medical breakthrough but the isolation was. We can decide whether it was insulin or isolation of insulin from Choice A which usually provides the intended meaning of the author. So, as per choice A it must be isolation that should be modified and insulin.
E)Although insulin was perhaps the most significant medical breakthrough of the twenties, its isolation was not revealed for over fifty years.
Same error as D change in intended meaning.

Hi Sir,

I am a little confused with the whole answer here.

In Option C, we are basically saying that “isolation of insulin was perhaps the most significant medical breakthrough”
That doesn’t make sense.

How can “isolation of insulation” be the “most significant medical breakthrough”? Isn’t it the “insulin” that is the “most significant medical breakthrough”?

Hi Vinit800HBS,

They're asking us to take a meaning call here: is it the substance itself that is the breakthrough, or is its isolation the real breakthrough? Isolation seems to suggest that other things were removed. That is, isolation seems to mean extraction. That sounds like something important.

However, this is not an official question, so it's fine if you feel that the GMAT won't test what sounds a little bit like a technical term.

There is another (more reliable) meaning call we can take here:

C ... the real story behind it was not revealed for over fifty years. ← This seems reasonable. The real story behind the breakthrough was not revealed for a long time.
E ... its isolation was not revealed for over fifty years. ← This option drops the real story bit altogether.

I think it's more likely that it was the story that was kept "secret" for 50 years (otherwise, why would the word "real" be used)? Effectively, option C says that a breakthrough happened in the 20s, but the real story behind that breakthrough came out much later.
