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

好像A正好说反了。passengers in cabins providing a view of the water 表明passengers的大脑接受两种不同的信息，比起passengers in cabins providing no view更容易患病。所以A改成more likely 才对。

A is correct.

Passengers in cabins providing a view of the water receive information of motion from two sources: the view of the water and the feeling of their inner ears.  Since information from both sources are consistent in indicating that they are indeed moving, they are less likely to get motion sickness.

Those poor passengers without the view of water get conflicting information: inner ears feeling indicate that they are moving, but their view does not confirm so.  So, they are more likely to get motion sickness.

还是不怎么明白，为什么宇航员员大脑认为没动，而站在甲板上大脑就认为动了呢？我觉得D很对呀，高手帮忙解释一下吧

坐过船就知道了——船摇得很厉害。

所以ETS出这道题暗含的一个假设就是大家都坐过船，呵呵。如果你不幸没有坐过船就完了。。。
