标题: 再问狒狒逻辑第9题
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.
答案为什么选A, A的对比关系好象与原文不一样呀,不太明白, 请帮忙解释

文中说的motion sickness是发生在人的两种感官接收到不同信息的条件下.

比如:耳朵的感官是静止的而眼睛的感官是运动的.

A正好符合这种"矛盾"要求;船舱里的人耳朵(因为文中提到耳朵在有重情况下可以感受到运动)可以感受到运动,眼睛却看不到.
