feifei逻辑第9题求助

9. Astronauts who experience weightlessness frequently get motion sickness. The astronauts see their own motion relative to passing objects, but while the astronauts are weightless their inner ears indicate that their bodies are not moving. The astronauts’ experience is best explained by the hypothesis that conflicting information received by the brain about the body’s motion causes motion sickness.

Which one of the following, if true, provides the strongest additional support for the hypothesis above?

(A) During rough voyages ship passengers in cabins providing a view of the water are less likely to get motion sickness than are passengers in cabins providing no view.

(B) Many people who are experienced airplane passengers occasionally get motion sickness.

(C) Some automobile passengers whose inner ears indicate that they are moving and who have a clear view of the objects they are passing get motion sickness.

(D) People who have aisle seats in trains or airplanes are as likely to get motion sickness as are people who have window seats.

(E) Some astronauts do not get motion sickness even after being in orbit for several days.

答案a
这我不太明白 题中说：内耳说不动，自已却看到自己动。可是a中不管是 passengers in cabins providing a view of the water还是 passengers in cabins 他们都没有看到自己动啊，这咋是加强呢？？

嘿嘿嘿～～sorry我逻辑不大好 还是有点不明白在a中大脑接受的信息咋冲突了？？

题目中说的假设就是：眼睛看到的  和  耳朵感知的  两种东西不同导致大脑接收干扰信息。
而A 选项就是在说明，在外面的船员和在里面的船员 耳朵感知的东西相同， 眼睛看到的不同  最终结果也不同，，跟原文假设是consistant、

我理解就是说 眼睛看到view可以减少sickness，inner ear 加剧sickness。
问加强，只有A符合，坐船，有view的乘客更不易于sickness，相对于no view的乘客

要支持的假设是receive了conflicting的information就会导致motion sickness.再看什么是conflicting information，原文给出了:The astronauts see their own motion relative to passing objects, but while ....are not moving.
明显就是当看到的和感觉到的不一样时，会产生motion sickness.
A是说，哪些能看到外面情况的，比不能看到外面的更少的患上motion sickness。（其实就是conflicting information received by the brain的问题，如果能看到，说明感受和看到是一致的，因为自己感觉在移动，看到也在移动嘛；反之，则是conflicting information ）

是这样的亲~~
题目中关键是对最后一句话的理解： The astronauts’ experience is best explained by the hypothesis that conflicting information received by the brain about the body’s motion causes motion sickness.

注意conflicting。也就是只有眼睛看到的和inner ears indicate的信息相反的时候才会感觉恶心。
问加强结论哦，而且还要strongest，思路是sample一定要具有代表性
加强结论有三种方法：举例子，否命题，解释结论。
答案Ａ：
During the voyage,说明船在动，
ship passengers in cabins providing a view of the water are less likely to get motion sickness than are passengers in cabins providing no view.
在船舱里有两种人：这一点限定调研对象A和B两种人是相对于船不动的，应该算是控制变量吧。学文的物理不好。
A人：能看见大海的，这种人实际动了，也看见和大海之间的动了，内耳反应和看到的信息一样反映的都是“我动了”；
B人：看不见大海，实际动了，但是看到的自己相对于船舱没有动，内耳反应和看到的信息出现冲突
所以：相对于A而言，B人更容易恶心。
属于举例子型答案~

再来分析一下B选项
坐飞机的人有时候恶心：首先occasionally，sample不具有代表性，可以排除；其次，没有信息显示conflicting information，所以不对。
C：有些坐车的人内耳反应自己动了，也能通过眼睛看到的东西判断自己动了，他们会感觉恶心-----显然，这两个信息是一致的，与conflicting相悖，却同样导致恶心，削弱了结论；其次，some passengers的sample同样不具有代表性，太弱，可以排除
（我觉得如果这个题问哪个最强削弱了结论的话也不能选C，因为有了some，削弱就不强，属于微削弱。。。open to discuss）
D:靠过道坐的人和挨窗户做的人恶心的可能性是一样的---信息量不足：这两种人在不同的环境下，也无从知道这两种人到底动没动，更不用说他们接收的信息是否conflicting---排除
E：有些宇航员在轨道里待几天就不恶心了---没有说conflicting，错；some的sample小，不具代表性，排除。


整合一下思路：首先，要选出最强加强结论的选项，含有一切显示sample不具代表性意义的答案都可以排除：排除BCE；
其次，进一步明确“加强结论”：三种方法：解释结论，举例子，否命题。
A是对结论的举例，控制变量，并凸显conflicting，有效加强，正确；
（不放心的话再看看D）：信息量不足，排除。

求大牛指正哇··

哈哈谢谢大家耐心解答～～！！明白拉拉～
