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.

答案为A.感觉A的例子与题目中的例子相反呢.nn帮忙解释一下.

providing a view of the water 在这里是什么意思？

“providing a view of the water ” －能看到水

题目里讲的conflicting information指inner ears和eyes同时接收到不同信息：一个静止，另一个运动，但并没有强调哪个是哪个。“conflicting information received by the brain about the body’s motion causes motion sickness.”

结论说motion sickness是由这种conflicting引起的

那为什么A起到了加强的作用呢？

谢谢您的解答！

因为没有窗户看不到水的移动但是内耳却感到身体在动 => 视觉与内耳感官不一致 => motion sickness
(A) 提供了另一个感观不协调会造成motion sickness的例子 => support.
