The cottontail rabbit population in Orange County, California, has increased unchecked in recent years as a result of the removal of the native fox population and the clearing of surrounding woodlands.

　　(A) years as a result of the removal of

　　(B) years as a result of removing

　　(C) years, resulting from the removing of

　　(D) years, which is a result of removing

　　(E) years, which is a result of the removal of

　　原文意思：

　　兔子数量增加是由 the removal 和 the clearing 两个原因导致的。

题目分析：

　　原文那两个原因由 and 连接形成并列，A 前后都是名词词组，可以用 and 连接，留着。

　　B 前面用 removing 是动名词，和后面的 the clearing 名词不对应，干掉。

　　C the removing 和后面 the clearing 对应，但是 resulting from 这个词的发起者是谁?这个选项没说，需要我自己填上去，不好，干掉。

　　D removing 和后面不对应，干掉。

　　E the removal 和后面可以对应，但是 which is a result of 显然没有 A 直接说好，选 A。
