11.The following appeared in a memo from the mayor of the town of West Egg.

"Two years ago, our consultants predicted that West Egg's landfill, which is used for garbage disposal, would be completely filled within five years. During the past two years, however, town residents have been recycling twice as much aluminum and paper as they did in previous years. Next month the amount of material recycled should further increase, since charges for garbage pickup will double. Furthermore, over ninety percent of the respondents to a recent survey said that they would do more recycling in the future. Because of our residents' strong commitment to recycling, the available space in our landfill should last for considerably longer than predicted."

1.居民的保证不能得出垃圾填埋地可以比预测的时间持续更久，保证并不能说明行动。

2.即便居民也作出了相关的行动，但是影响持续时间的长短并不一定仅仅和居民的行动有关，也可能和城市的环境污染，工业发展等条件有关系。

3.作者的调查缺乏说服力，没有给出总数，90%只是一个比例而已，也许总的样本数并不是很多。

4.坐着在文中只是说明了最近两年铝和纸的循环利用加强了，这并不能说明其他垃圾的循环利用也加强了。
