一道逻辑题,绕了半天没想通啊!!!

Ordinary mountain sickness, a common condition among mountain climbers, and one from which most people can recover, is caused by the characteristic shortage of oxygen in the atmosphere at high altitudes. Cerebral edema, a rarer disruption of blood circulation in the brain that quickly becomes life-threatening if not correctly treated from its onset, can also be caused by a shortage of oxygen. Since the symptoms of cerebral edema resemble those of ordinary mountain sickness, cerebral edema is especially dangerous at high altitudes.

 

Which one of the following is an assumption on which the argument depends?

 

(A) The treatment for ordinary mountain sickness differs from the treatment for cerebral edema.

(B) Cerebral edema can cause those who suffer from it to slip into a coma within a few hours.

(C) Unlike cerebral edema, ordinary mountain sickness involves no disruption of blood circulation in the brain.

(D) Shortage of oxygen at extremely high altitude is likely to affect thinking processes and cause errors of judgment.

(E) Most people who suffer from ordinary mountain sickness recover without any special treatment.

答案(A)

E为什么不选,如果高原反应不用治疗就好了,Cerebral edema不治就死了,那么如果C被认为是高原反应,岂不是特别危险

请高手明示!!!

有点明白了

非常感谢非常感谢

 e属于过度推理,Most people who suffer from ordinary mountain sickness

recover without any special treatment.不能推到CE需要经过Special treatment。

E当然不选,E是fact,不是假设。

我觉得题目的意思是找出没说出的话,也就是隐含假设。

凡是说出来的,基本是已知事实。

Ordinary mountain sickness, a common condition among mountain climbers,

and one from which most people can recover

论据:

第一句讲普通高山病(假设为A)

普通高山病是由于在高纬度缺少氧气而引起。该病可以被绝大多数人克服。

(普通高山病在高纬度(假设为C)不危险)

第二句讲CE(假设为B)

CE这种病是一种由于大脑血液循环被打断而这种打断如果没有在其发生的时候被正

确治疗很快变得威胁生命。

第三句讲结论:

既然CE这种疾病同普通高山病相似,那么,CE在高纬度特别危险。

逻辑线:

结论:A和B相似(A在条件C下不危险,第一句隐藏),B在C条件下危险。

那么,肯定存在假设A和B在C条件下不同的地方,不然因为A和B相似,而A在C条件

下不危险,只会得到相反结论:B在C条件下不危险

翻译和解释可能不太好

不过还是贴出来希望能提供点思路
