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.我的问题是:providing a view of the water是动的一面，但是在船上实际又没有动，这样不是与题目意思违背了吗？不懂啊

自己顶一下!请各位帮助一下下啦

船怎么会实际没有动呢？During rough voyages 在艰难的一次海上航行中~

船要都不动，怎么说是艰险呢。呵呵

providing a view的人接受的信息是不矛盾的。因为船动，他也能看到水动

为什么是less likely，我觉得看到水动更应该得病呀，感觉和文中的相反

解题的关键在于对conflicting information received by the brain的理解，而不是具体的例证，题目中关于宇航员的具体例证只是conflicting information received by the brain中的一例，仅此而以。

题目的意思是：人是有两个方面的信息可以来判断自己是否在运动，1是人在失重状态下内耳会感知为人不在运动；2是人通过看周围的物体在移动而感知自己在运动。宇航员运动时能看见周围物体在移动，但由于失重其内耳却感知为他不在运动，所以引起motion sickness。

问加强这个观点的例子。A是最好答案。

A说的是在动荡得很利害的船上，看得不见海水的人比看得见海水的人容易晕船。

这是因为此时人不在失重状态，所以内耳感知得到人在运动；但同时看不见海水的人就不能从周围物体的移动感知到自己的运动，这就引起conflict；但对于能看得见海水的人这两个渠道提供的信息是一致的，所以比较不容易晕船。
