Ambiguity of "It" "saying" and "researchers "which is not there in the original sentence.

I guess this is a very poor question.

Experts kindly help. I eliminated C and chose B.

How are these two the same?

"In a recently conducted study, Harvard Scientists ..." and

"In a recently conducted study by Harvard scientists, ..."

The first can refer a scenario that a study is done by many scientists, but Harvard scientists did something special.

The second refers a scenario that study is only done by Harvard scientists.

Am I wrong here?

Official Solution:

In a recently conducted study, Harvard Scientists have linked a molecule to PGC-1 alpha FNDC5, a protein that enhances the expression of brain-health, not only as promoting the development of new nerves and synapses in the hippocampus of the adult brain, but also preserving existing brain cells.

A. In a recently conducted study, Harvard Scientists have linked a molecule to PGC-1 alpha FNDC5, a protein that enhances the expression of brain-health, not only as promoting the development of new nerves and synapses in the hippocampus of the adult brain, but also preserving existing brain cells.
B. In a recently conducted study by Harvard Scientists, a molecule PGC-1 alpha FNDC5, a protein enhancing the expression of brain-health, not only promotes the development of new nerves and synapses in the hippocampus of the adult brain, but also preserves existing brain cells.
C. In a recently conducted study by Harvard Scientists, the researchers have linked a molecule to PGC-1 alpha FNDC5, a protein that enhances the expression of brain-health, saying that it not only promotes the development of new nerves and synapses in the hippocampus of the adult brain, but also preserves existing brain cells.
D. Linking a molecule PGC-1 alpha to FNDC5, a protein that enhances the expression of brain-health, Harvard Scientists claim that the factor not only promotes the development of new nerves and synapses in the hippocampus of the adult brain, but also preserves existing brain cells in a recently conducted study.
E. In a recently conducted study by Harvard Scientists, which linked a molecule PGC-1 alpha to FNDC5, a protein enhancing the expression of brain-health, it not only promotes the development of new nerves and synapses in the hippocampus of the adult brain, but also preserves existing brain cells


A. not only as promoting, but also preserving -- unparallel

B. distorted meaning; It looks as if the molecules promotes something in a study

C. Correct Choice

D. “preserves existing brain cells in a recently conducted study" means that the preservation was done in a study and not outside

E. It is not clear what is the referent for the pronoun ‘it’; it may refer to study or the molecule


Answer: C


Doesn't C has a pronoun error? (It) can reefer to protein or molecule. Right?


GMAT actually allows slight pronoun ambiguity such as this one: When a pronoun is a subject of a clause, it would refer to the subject of another clause by virtue of parallelism, although there could be more than one possible antecedents.

In option C, "it" is a subject of a clause and hence refers to "protein" ("that"), which is the subject of another clause - "molecule" is an object.



Option C introduces a new term researchers in the sentence, this is nowhere present in the original sentence. This distorted the meaning and confused me. If the term researchers was replaced by scientists then C would be the best answer.
