My point: Answer choice A MAY BE TRUE, but this is a MAIN POINT question type, in which the correct answer choice not only MUST BE TRUE but also must be the conclusion of the stimulus. MAIN POINT question is a special MUST BE TRUE question. There are two kinds of incorrect answer choices of MAIN POINT questions: 1.The answer choice may be true , but not must be true. 2.The answer choice must be true , but not the main point of the stimulus.
这道题问的是conclusion 是什么(也就是argument是什么)。
猛一看,A和E都对, 但是在看下题干,。。。。is no longer endangered. This is a specious argument....,所以conclusion 应该和 endangered 有关,选E。
