尽管盂偌一贯胃口不好,但是他却非常喜欢他在T饭店吃的三顿饭。然而不幸的是他每次饭后都得了病。第一次他吃了一块巨大的香肠比萨饼外加一道辣椒:第二次他尽其所能吃了“吃你所能吃炸虾”和辣椒特价菜;第三次他就着辣椒吃了两个T饭店的大肉团三明治。因为这三顿饭中每次都有的菜,只有辣椒,所以孟偌推论出他生病就是因为T饭店的辣椒。
盂偌的推理最易受到下面哪一项的批评?( )

A.作为得出他的结论的基础。孟偌在T饭店食用的包括辣椒的饭的次数太少了
B.他在没有确定假设的原因是否先于假设的结果的情况下,假定了一个因果关系
C.他没有证明每个在T饭店吃过辣椒的人都生了病
D.他忽视了这样的事实,即对他来说所有这三顿饭他都吃得太多了

答案

参考答案:D

解析: 评价型题目。题干中孟偌根据三顿饭中都有的菜只有辣椒,推出是他生病的原因是辣椒。要使这个推理正确,就需要假设三顿饭没有其他共同的因素。D项指出三顿饭还有一个共同的因素“吃得太多”,而这一因素也是容易导致生病的原因.则推翻了孟偌的推理。故选D。
