From 1978 to 1988, beverage containers accounted for a steadily decreasing percentage of the total weight of household garbage in the United States. The increasingly widespread practice of recycling aluminum and glass was responsible for most of this decline. However, although aluminum recycling was more widely practiced in this period than glass recycling, it was found that the weight of glass bottles in household garbage declined by a greater percentage than the weight of aluminum cans.
Which of the following, if true of the United States in the period 1978 to 1988, most helps to account for the finding?
(A) Glass bottles are significantly heavier than aluminum cans of comparable size.
(B) Recycled aluminum cans were almost all beverage containers, but a significant fraction of the recycled glass bottles had contained products other than beverages.
(C) Manufacturers replaced many glass bottles, but few aluminum cans, with plastic containers.
(D) The total weight of glass bottles purchased by households increased at a slightly faster rate than the total weight of aluminum cans.
(E) In many areas, glass bottles had to be sorted by color of the glass before being recycled, whereas aluminum cans required no sorting.
问题分析：A说相同大小的玻璃瓶和铝罐子哪个更沉，这个比较对象显然没有提过，就好像原文说英吉比他妈妈高，有一个选项说英吉比他老婆高一样，这个选项无法影响原文我比我妈高这个现象，但是仍然再谈论高度问题这个选项才会有迷惑性。B 说除了beverage之外的其他产品，范围不对，杀。C 说生产商又什么样的容器，到底是玻璃的还是铝制的，和原文内容有关，原文反复谈的就是用什么样的瓶子，留着。D 说重量增加速度快慢，没说，杀。E 说是否需要分类，很扯的一个选项，杀！
