Feifei-91 again

91. Leachate is a solution, frequently highly contaminated, that develops when water permeates a landifill’s site. If and only if the landfill’s capacity to hold liquids is exceeded does the leachate escape into the environment, generally in unpredictable queantities. A method must be found for disposing of leachate. Most landfill leachate is sent directly to sewage treatment plants, but not all sewage plants are capable of handling the highly contaminated water.

Which one of the following can be inferred from the passage?

(A) The ability to predict the volume of escaping landfill leachate would help solve the disposal problem.

(B) If any water permeates a landfill, leachate will escape into the environment.

(C) No sewage treatment plants are capable of handling leachate.

(D) Some landfill leachate is sent to sewage treatment plants that are incapable of handling it.

(E) If leachate does not escape from a landfill into the environment, then the landfill’s capacity to hold liquids has not been exceeded.

(E) is provided as the right answer.  I don't understand why (D) is wrong.  If most leachate is sent to sewage treament plants, but not all sewage plants are capable of handling the water => some leachate must have been sent to plants that can't handle it.

Xie Xie a lot!!!!!

加点我的理解，根据原文的内容not all sewage plants are capable of handling L.那么假设只有一家厂无能力处理，那么D项应该改为some L is sent to a sewage treatment plant that is incapable of handling it.所以D项并不能包涵所有情况。

INFER题应该是在所有情况下都成立的选项~

逆否命题。题目不难，但费费逻辑里把sewage treatment plants翻成可被污水灌溉的植物。。。汗啊

这个幽默！顶一下！
