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。
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)
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?)
