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.
答案是A
思路：搭桥法，建立A与B的联系。仔细读题可知：这种运动性疾病是由于大脑接受了不同的矛盾的信息。有两个信息源：一个来自内耳（静止），一个来自眼睛（运动）。

选项中只有A,C,D涉及这样两个信息源。

A指出接受两种不同的信息较容易获得运动性疾病比起获得两种一致的信息。C：虽有两种信息，但两者是一致的（都是运动的）。

C, D：指出接受两种一致的信息较容易获得运动性疾病比起获得两种不同的信息。与题目的例子相反。所以只有A是正确选项。

这是NN们的解释，但是我还是不懂A的意思，A的情况指的不同的矛盾信息是什么？难道是一个内耳是运动的，但眼睛看的cabins里的东西是静止的？

For any CR problems, focus on the main conclusion.

In this case the conclusion is:
The astronauts’ experience is best explained by the hypothesis that conflicting information received by the brain about the body’s motion causes motion sickness.

Now we need to find a strengthener. Either conflicting info to the brain leads to motion sickness or conforming info to the brain leads to no motion sickness.

A fits the bill. What a passenger sees and what a passenger senses (through his or her ears) are the information received by the brain.

我的理解是...
基于Sdcar2010的解释答案要是个a strengthener. Either conflicting info to the brain leads to motion sickness or conforming info to the brain leads to no motion sickness.

A选项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就是将有conflicting info的和conforming info的比较。这句话里前面的ship passengers in cabins providing a view of the water 是conforming info, 因为脑中的意识知道自己是在船上航海，眼中所见的呢也是海面。而后面与之对比的passengers in cabins providing no view, 他在屋子里，眼中所见的是在陆地房间里一样的东西，这和自己脑中意识加起来属于conflicting info
