大全405——答案也有问题啊，严格地讲，没一个是对的（个人观点）

405.        In the face of widespread concern about environmental waste, compact disc manufacturers are attempting to find a replacement for the disposable plastic box in which they package their product. A

(A) the disposable plastic box in which they 有歧义！可理解成他们在box里面

(B) the disposable plastic box where they

(C) a disposable plastic box in which to

(D) disposable plastic boxes inside which they（A）

(E) the disposable plastic boxes in which to

大家看看A选项，有两种理解：

1、他们在box里package their product

2、他们把their product package 到box里

我觉得两种都行，也就是说，该选项有歧义啊！

第一种理解逻辑不合理，所以只有第二种理解。也即不会产生歧义。通常也是优先吧in which放到定从最后来理解的。
