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?
ADuring 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.
ADuring 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A. 但A是说在航海途中，坐在船舱内看不到外面在运动的，更容易得病。可是，坐在船舱里内耳的感觉就是静止的，而看到的也是静止的，这应该不容易得病啊？！
答案A.

崩溃了……整了半天版面还是这么混乱，奇怪了？！大家就将就一下哈~~真是不好意思~
^^
原题中hypothesis的意思是说当看到的和内耳实际感觉到的不一致时，会有motion sickness。两者一致时，不容易有motion sickness。（请注意：内耳是可以感觉到实际有没有在动的）
A中提供了这样的信息。当内耳感觉到移动时，给乘客看一个动的东西a view of the water，不容易得motion sickness，相比于那些看不到移动物体的乘客。
题目中说while the astronauts are weightless their inner ears indicate that their bodies are not moving.也就是说，在内耳中的感觉是不动的，所以这是与眼睛所看到的运动是相反的，所以会得motion sickness。
由于A中也没提到内耳究竟感觉到的是动还是不动，我就假设它和题目中给出的信息是一致的，那也就是说我理解的A是内耳感觉到的是不动，正好和你说的相反了，可我现在不明白自己是哪个地方理解错了？！
谢谢！！
呵呵，首先这里有个常识性问题：内耳是人体的平衡器，是能知道实际情况的。
其实内耳与题目无关，排除这个内耳的问题也同样可以解题。the hypothesis that conflicting information received by the brain about the body’s motion causes motion sickness. 这里已经说明是conflicting information（信息的不一致）导致motion sickness。只要在选项中找到支持这个信息就是正确选项。
A说一致的情况比不一致的情况less likely to get motion sickness.(而且A中并没有涉及内耳)
does it make sense?
A是说，在航海途中看到水的（即看到的是动态的）比没看到（即看到静态的）更不容易得病。
你的意思是说，当航海时人们确实是随着船在前进的，所以是动态的。而看到水也是动态的，所以一致，就不容易得病是吧~
可是题目中说astronauts see their own motion relative to passing objects,也就是说看到的是动态的，而inner ears indicate that their bodies are not moving，也就是说内耳的感觉是静态的。可实际确实是在运动的啊？！那不就成了看到的与实际一直才更容易得病？！（by the way 是不是我题目没有读懂啊？！题目的意思是说实际在运动呢吧？）
是的，是因为你题目没有读懂。这里是说实际上人没动，但他们看到的东西动了，所以他们觉得自己动了（但实际上他们没动）。
这道题完全可以把前面的背景陈述抛开，不用考虑。
直接看hypothesis是什么，然后找支持hypothsis的选项。
抓住主线：conflicting information -->motion sickness.
哦!!明白了!
谢谢 laipiyu !!
