Most disposable plastic containers are now labeled with a code number (from 1 to 9) indicating the type or quality of the plastic. Plastics with the lowest code numbers are the easiest for recycling plants to recycle and are thus the most likely to be recycled after use rather than dumped in landfills. Plastics labeled with the highest numbers are only rarely recycled. Consumers can make a significant long-term reduction in the amount of waste that goes unrecycled, therefore, by refusing to purchase those products packaged in plastic containers labeled with the highest code numbers.
Which one of the following, if true, most seriously undermines the conclusion above?
(A) The cost of collecting, sorting, and recycling discarded plastics is currently higher than the cost of manufacturing new plastics from virgin materials.
(B) Many consumers are unaware of the codes that are stamped on the plastic containers.
(C) A plastic container almost always has a higher code number after it is recycled than it had before recycling because the recycling process causes a degradation of the quality of the plastic.
(D) Products packaged in plastics with the lowest code numbers are often more expensive than those packaged in the higher-numbered plastics.
(E) Communities that collect all discarded plastic containers for potential recycling later dump in landfills plastics with higher-numbered codes only when it is clear that no recycler will take them.

我选D，但答案选C，但我认为C是不正确的，因为C项没有谈到质量，质量高是9不是质量低是9。
一般地认识是，能被降解的塑料盒一般都比较贵，生产工艺比较复杂，质量要求也比较高

原文说：是否选择标号高的容器
Which one of the following, if true, most seriously undermines the conclusion above?
(A) The cost of collecting, sorting, and recycling discarded plastics is currently higher than the cost of manufacturing new plastics from virgin materials. 说成本怎么比其他高无关
(B) Many consumers are unaware of the codes that are stamped on the plastic containers.
顾客对什么标号不理解不理解和我关注的事情有关系么干掉
(C) A plastic container almost always has a higher code number after it is recycled than it had before recycling because the recycling process causes a degradation of the quality of the plastic. 说瓶子在利用过之后标号通常高有关
(D) Products packaged in plastics with the lowest code numbers are often more expensive than those packaged in the higher-numbered plastics. 说低标号的比高的更贵和原文说的是否选择标号高的容器事也有关 lowest绝对化去掉D
(E) Communities that collect all discarded plastic containers for potential recycling later dump in landfills plastics with higher-numbered codes only when it is clear that no recycler will take them all绝对
我在剩CD时按照不好的词排除了D
