费费逻辑9题。始终想不明白，也可能是读不懂。越研究就越糊涂了。恳请各位同学讲清楚也行，告诉我怎么快速排除也行（技巧），谢谢！
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.

eople 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。

原文conclusion是：
conflicting information received by the brain about the body’s motion causes motion sickness.
只有A提供了conflicting information：
在一个带有能看到运动的水的隔间里的人甲，比，在一个什么也看不到的隔间里的人乙，less likely得病。
因为甲没接受到conflicting information（看到水动从而知道自己在动，inner ears indicate that their bodies are moving），而乙接受到了（相对静止的自己，inner ears indicate that their bodies are moving），所以甲比乙less likely得病，从而support

谢谢楼上好同学~！我自己来详解下：
题干：宇航员在weightless下容易的motion sickness. 宇航员要通过看见其他物体的相对移动才能得知自己在运动。当weightless状态下，宇航员的内耳提示他们是静止的。这种sickness可以由一个假设来解释，那就是：宇航员大脑所接收到相矛盾的的信息（明明自己在动，但内耳提示自己却是静止的）造成了这种motion sickness.
问：哪个进一步提供支持（例证）
A.看见水的与看不见相对运动的乘客比不容易得病（看见水动的乘客，有了相对运动的参照物。而看不见的自己在动，但无重状态下内耳提示自己是静止的，所以矛盾造成sickness)
B.飞机上的乘客（没有视觉和内耳静止上的冲突）
c.内耳显示运动，视觉显示也是运动（没有冲突）
d.有视觉信息和没视觉信息的得病率一样（完全瞎说）
e.无关选项

硬解的，错误之处还请指教
