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,但此题我觉得题干是讲因为眼睛看到运动,而内耳却说不动,二者矛盾才产生这种病. 但若A所述,看到船外景观的反而比没看到的更不易得病,那A就不是加强,而是削弱才对,怎么会是A?

请指点.

      the passage presents the fact that when conflicting information received by the brain,  people get motion sickness

      A:  ship passengers in cabins providing a view of water--->they can see their motion( because they do not experience weightless, they inner ears tell them that they are moving)--->the information received by their brains is consistent--->they are not likely to get motion sickness

           ship passengers in cabins providing no view--->they can not see they are moving--->the information received by their brains is inconsistent--->they are likely to get motion sickness

       the line of reasoning of this question is complex ,  I choose D for the first time.

A的ROUGH意思为：剧烈颠簸的。在船仓内，感觉是船在动，眼睛看到的却不再动，这两个矛盾信息导致MOTION SICKNESS。能看外景，却眼睛和身体感觉都一样是船在动
