单选题 Many consumers are concerned about the ecological effects of wasteful packaging. This concern probably explains why stores have been quick to stock new cleaning products that have been produced in a concentrated form. The concentrated form is packaged in smaller containers that use less plastic and require less transportation space.
Which of the following, if true, most seriously undermines the explanation offered above?

A、 Few consumers believe that containers of concentrated cleaning products are merely small packages of regular cleaning products.
B、 The containers in which concentrated cleaning products are packaged are no harder to recycle than those in which regular cleaning products are packaged.
C、 Those concentrated cleaning products that are intended to be used diluted have clear instructions for dilution printed on their labels.
D、 The smaller containers of concentrated cleaning products enable supermarkets and drugstores to increase their revenues from a given shelf space.
E、 (E) Consumer pressure has led to the elimination of wasteful cardboard packaging that was used for compact discs.

【正确答案】 D

【答案解析】[解析] 本题是对一种现象提出一种解释，商业购进浓缩形式生产的清洁产品是因为消费者的关注。如果浓缩清洁产品的较小容器可以使得超市与药店增加他们来自于特定货架空间的收入，正如(D)所说，那么就从另外一个角度解释了商业为什么购进浓缩形式生产的清洁产品，也就weaken了上面提出的解释是因为消费者关注的原因，所以(D)正确。
