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

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。

不是很明白A

A说在舱外能看见水的人相对于在舱内看不到的人更不容易患病。 也就是说舱内的人接受两种不同信息，而舱外的人接受两种一致信息----但是为什么舱内的接受两种不同信息呢？他们看不见外面的水啊？？这不是就一种信息么？而舱外的才应该接受两种信息阿：一种他们在船上静止，另外一种看见水运动阿~~~~救命啊！！！！

Hey, take it easy, man

I think you need to read the question carefully

舱内的接受两种不同信息.

One 信息 is 他们看不见外面的水, so their eyes tell them that they are still.

Second: the ship is moving and "their inner ears indicate that their bodies

are moving".

Just the opporiste of " while the astronauts are weightless their inner ears

indicate that their bodies are not moving"

just my 2 cents.
