　　Astronauts who experience weightlessnessfrequently get motion sickness. The astronauts see their own motion relative topassing objects, but while the astronauts are weightless their inner earsindicate that their bodies are not moving. The astronauts’ experience is bestexplained by the hypothesis that conflicting information received by the brainabout the body’s motion causes motion sickness.

　　Which one of the following, if true, providesthe strongest additional support for the hypothesis above?

　　A. Duringrough voyages ship passengers in cabins providing a view of the water are lesslikely to get motion sickness than are passengers in cabins providing no view.

　　B. Manypeople who are experienced airplane passengers occasionally get motionsickness.

　　C. Someautomobile passengers whose inner ears indicate that they are moving and whohave a clear view of the objects they are passing get motion sickness.

　　D. Peoplewho have aisle seats in trains or airplanes are as likely to get motionsickness as are people who have window seats.

　　E. Someastronauts do not get motion sickness even after being in orbit for severaldays.

　　答案：A

　　思路：搭桥法，建立A与B的联系。仔细读题可知：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)。

　　选项中只有A,C,D涉及这样两个信息源。

　　A指出接受两种不同的信息较容易获得运动性疾病比起获得两种一致的信息。C：虽有两种信息，但两者是一致的(都是运动的)。

　　C, D：指出接受两种一致的信息较容易获得运动性疾病比起获得两种不同的信息。与题目的例子相反。所以只有A是正确选项。
