Prospecting for gold during the California gold rush was a relatively easy task,（because of erosion, prehistoric glacier movement, and ancient, gold-bearing riverbeds thrust to the surface by volcanic activity put gold literally within reach for） anybody with a pan or shovel.
A. because of erosion, prehistoric glacier movement, and ancient, gold-bearing riverbeds thrust to the surface by volcanic activity put gold literally within reach for
B. because of erosion, prehistoric glacier movement, and volcanic activity that thrust ancient, gold-bearing riverbeds to the surface, and putting gold literally within reach of
C. owing to erosion, prehistoric glacier movement, and volcanic activity that had thrust ancient, gold-bearing riverbeds to the surface, and putting gold literally within reach of
D. since erosion, prehistoric glacier movement, and volcanic activity that thrust ancient, gold-bearing riverbeds to the surface, putting gold literally within reach for
E. since erosion, prehistoric glacier movement, and ancient, gold-bearing riverbeds thrust to the surface by volcanic activity put gold literally within reach of
答案选E，但是怎么感觉不平衡呢

本题考查并列结构固定搭配

A选项中because of 后面为名词并列，erosion, movement and riverbeds 但put的存在很奇怪，如果为动词则of后面存在了完整主谓结构，如果作为过去分词则gold多余排除A
BC选项中and作为并列结构的引导词，putting分词之前没有与之并列的结构；排除BC

within reach of为固定搭配，within reach for不对，排除AD

E选项为正确选项

希望这样的解释能够帮助你
