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.

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


首先我想问 since和because of 的区别
因为我觉得 since只有做连词时才有“由于，因为”得意思
那么E选项 since后面跟的一连串名词怎么解释呢？不是应该跟句子吗？
即便那个ancient和gold-bearing同时修饰riverbeds 不是会产生歧义嘛 因为ancient也有名词的意思

所以我觉得这个题有点问题 请高手赐教
