Astronauts who experience weightlessness frequently get motion sickness. They see their own motion relative to passing objects, but while the astronauts are weightless their inner ears indicate that their bodies are not moving. This 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.


The conclusion of the argument is that the conflicting information received by the brain about the body's motion causes motion sickness. Now to support this or to stregthen this , I have to cite another example where the person recieves a conflicting information from brain.

How could A be correct here ?

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.

I understand it as the passenger who have the view will be able to see the rough waves and hence feel the motion while their inner ears would tell them that their bodies are not moving. So they should be more likely to have motion sickness.

B) Does not explain
c) no conflicting info so doesnt strengthens the hypothesis.
d) weakens the hypothesis
e) does not explain

Please explain .
