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.

我选A。

A?

不确定..

阿一

文中假设是“conflicting information causes motion sickness. ”

选项A中，轮船上，肯定能够感觉到移动，但是在封闭的船舱，视觉接受到的信息是没有移动，所以是conflicting的，所以封闭船舱容易motion sickness

A，因为它和原文给的条件一致

非常感谢大家的参与。。。呵呵

标答是A

特别感谢各位的解释

之所以贴出来，是因为觉得A说反了，以为看不见就没有conflict,看得见水才会有conflict。。。没有反应过来。。中学物理做多了。。有对参照物先入为主的潜意识。。

是feifei 135里的题。。最大问题是超时，没办法5分钟3题。。
