问题 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.
选项 A、the disposable plastic box in which they
B、the disposable plastic box where they
C、a disposable plastic box in which to
D、disposable plastic boxes inside which they
E、the disposable plastic boxes in which to
答案 A
解析 把划线部分的定语从句还原，就是：they package their products in boxes。因而A没有错误；同时可看出D是错的，介词inside的使用不准确。此句的关键在于：判定disposable plasticbox是特指还是泛指。从句意上看，这种盒子是现有的，并用于包装特定产品的，显然应该用特指，因而在前面应加the，由此排除C；B中用where是模糊的，在GMAT公理中，我们已强调在引导定语从句时，in which或其他介词+which一定优先于where；只剩A和E，E有the，且inwhich to的表达方式很简洁，E岂不比A更好?但E的缺陷在于它用了复数形式boxes而非A中的单数box，A表明现有的这一种盒子，在特指的情况下包括了很广的范围(整个compact disc行业)，而E中的the boxes却把范围缩小了，似乎表明某一批或某一时期的这么多的盒子，显然A反映了原意。从集合角度理解为：the box表示全集，the boxes是the box的一个子集。
