还没有题目讲解（毕出老师会陆续发布对官方考题的解读，请保持关注）。
A D introducing 可以排除
而个人认为CE的主要区别是 since 修饰的动词是不同的。
C中 since 这句话修饰的是that has grown rampant in the southern United States 因为后面有逗号隔开，就近修饰原则
而E中的since 前被逗号隔开直接修饰了 has overrun many houses and countless acres of roadside.
在B中since 这句前后都有逗号，我不确定，但是我认为如果当做插入语即状语位置可以移动这一特点的话，这个也是修饰主句谓语部分的。且 这里很容易判断出用 to do 也是可以pass 掉的
但是在逻辑上 它在...时候被引入应该是修饰它疯长的。所以选择C。
