It is possible that, like the Volkswagen, whose unchanging exterior over decades concealed many changes in its internal machinery, the evolution of many prehistoric microbes occurred with no significant modification to their sheaths.

(A) the evolution of many prehistoric microbes occurred with no significant modification to their sheaths

(B) the evolution of many prehistoric microbes was occurring without significant modification of their sheaths

(C) no significant modification was made to the sheaths of many prehistoric microbes as they were evolving

(D) the sheaths of many prehistoric microbes went without significant modification during their evolution

(E) many prehistoric microbes evolved without significant modification of their sheaths

Hi,
I think in D, 'their' can refer to sheaths or microbes. if it refers to sheaths, it could mean only about the evolution of sheaths and not the microbes as a whole. Moreover the comparison is with Volkswagen and its description is about its interiors(i.e its parts). So, the comparison would be apt if it is compared to microbes as a whole and its description about its parts(sheaths).
Hence, E is better.

Cheers!

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
