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.

The given answer is A. What is the specific meaning of A？ Why is A better than B，which is my choice?

请注意 conflicting 这个词。

题干中 hypothesis 是，宇航员的大脑接收了两种conflicting 的信息：

（1）宇航员身体与其他物体有相对运动（也许是通过眼睛反射到大脑的）
（2）宇航员的内耳却反聩到大脑的信息是：宇航员的身体与其他物体没有相对运动。

这两种conflicting 的信息导致了 motion sickness.

选项A中的情景实际 Suggest 了这样一种 Conflicting 的信息，有支持作用。

而选项B是无关选项。既没支持也没反对作用。

"roviding a view of water"指的是消除了宇航员的judging“their own motion relative to passing objects”这种感觉，所以，就不存在这种conflicting information。

是这个意思嘛？

现在看看，好像B当中experienced airplane passenger和题目中的astronauts还是不太一样的，因为文中还又一个条件weightlessness.

这样理解可以吗？

我的理解和你的已差不多了。

换个说法是： 你用题干中的 hypothesis 可以解释得通选项 A 的情形。

而B选项的描述与hypothesis一点关系都没有，更谈不上support 了。

嗯，谢谢了
