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.

不太明白A的意思，哪位能帮忙解释一下啊？谢谢啦。

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.

我的理解是这样的：产生motion sickless是因为大脑所接受到的矛盾的信息，即宇航员看到自己在运动但由于失重，他们的内耳告诉他们，他们的身体没有动。A中，在船舱能看到水的乘客看到自己在运动（相对于水），而此时并没有处于失重状态，所以内耳提供给此类乘客的信息也是他在运动，大脑没有接受矛盾的信息；而看不到水的乘客，就看不到自己的相对运动，但内耳告诉他们，他们是在运动的。比较两种乘客，自然就得到A的结论了。
