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
原文意思：就像大众车一样，内部有翻天覆地的变化而外表不变。虽然很多史前的microbes在sheaths上变化不大，但是microbes本身还是在进化的
题目分析：前面说like the volkswagen，就证明划线部分应该和这个volkswagen对应，与这个对应的只有E了。今天题目出奇的简单，打完收工！
