题目分析：
本题的大概意思是：
在加州黄金淘金热时期探金是很容易的事情，冲蚀，史前冰山运动，被火山运动推到地表来的古老的产金河床把金子放到有淘金盘或铲子的人们触手可及的地方
另外，本题还涉及到习语的问题，reach for sth.：伸手抓某物；reach of sb.：在某人能触及到的范围内
选项分析：
A选项：because of是介词，身后只能接名词或名词短语，不能接句子。在本题中，because of身后是一个完整的句子，谓语动词是put；reach for anybody含义错误。
B选项：because of身后的名词词组的核心词为erosion, prehistoric glacier movement, and volcanic activity。在逻辑上，“淘金很容易”的原因是“侵蚀使得金子暴露”这件事，而不是“侵蚀”本身。
C选项：owing to和because of相似，没有错误。核心词错误同选项(B)。
D选项：连词since身后引导原因状语从句，该从句缺少谓语动词。
E选项：Correct. 本选项在语法和逻辑上均是正确的。erosion, prehistoric glacier movement, and ancient, gold-bearing riverbeds三者并列没有问题，三者确实都是行使put这一动作的事物，虽然前两个是抽象性名词，后者是具体的实物名词，但功能相同，可以并列。thrust在此为过去分词。
Prospecting for gold during the California gold rush was a relatively easy task, 【since 】erosion*, prehistoric glacier movement*, and ancient, gold-bearing riverbeds* （thrust to the surface by volcanic activity）【put 】gold literally 【within reach of】 anybody with a pan or shovel.
在加利福尼亚淘金热期间寻找黄金是一件相对容易的事情，【因为】侵蚀、史前冰川运动、（被火山运动推到地表来的）古老的产金河床，使任何人用平底锅或铲子都可以【接触到】黄金。
reach for sth.：伸手抓某物；
reach of sb.：在某人能触及到的范围内--【within reach of】 anybody
erosion 抽, prehistoric glacier movement 抽 , & ancient, gold-bearing riverbeds实
三者并列没有问题，因为都可以发出put这一动作，虽然前两个是抽象性名词，后者是具体的实物名词，但功能相同，可以并列。
thrust在此为过去分词，修饰 reiverbed
