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。
我的理解是：文中说人看见自己动，但同时感觉自己没动，就会得运动病。
A里面，坐在船上窗边的人看见自己在动，但感觉是美懂得，应该是更容易得病啊，为什么反而是比较不容易得病呢？我觉得应该是D对。
请教大家！
题目说：失重使内耳感受不到自己在动。因此，在不失重时，人的内耳是可以感受到自己在动的。
因此在非失重情况下，支持hypothesis that conflicting information received by the brain about the body’s motion causes motion sickness，的应该是看不到自己在动，但能“内耳感受动”（实际在动）的情况
A）说看见动者less sick than看不见的
D）说看不见者as sick as 看的见的
题目说：失重使内耳感受不到自己在动。因此，在不失重时，人的内耳是可以感受到自己在动的。
sorry，对这句话有一个小小的疑问：原命题：“失重使内耳感受不到自己在动”，其否命题：“在不失重时，人的内耳是可以感受到自己在动的”一定正确吗？
