Sentence Correction (SC) | Re: The ability of neuroscientists to pinpoint the exact locations in the

Hi i may not be an expert, But am glad to throw some light on how i solved the question.

E is wrong because The ability by itself can not become more precise. Moreover An ability cannot become precise but we can precisely pinpoint.

Only C says that they are now able to PRECISELY Pin point.

Furthermore, GMAT loves to use verbs rather than noun where ever possible. So i opted C over E.

Thank you
