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，我有点不理解。 根据题意这种运动性疾病是由于大脑接受了不同的矛盾的信息。有两个信息源：一个来自内耳（静止），一个来自眼睛（运动）”，也就是说，如果不让宇航员看到东西，没有来自眼睛的运动，这种矛盾的信息就可以避免 但选项A讲的是能看到东西的人比不能看到东西的人得病的可能性要小，这不是与题意相反了吗? |
