   During rough voyages ship passengers in cabins providing a view of the water are less likely to get motion sickness than are

   Why this is right

   This strengthens the plausibility by showing when the cause is present, the effect is present; and when the cause is absent, the effect is absent. Passengers on a boat that is traveling over rough waters will all FEEL that their bodies are moving. The passengers who have a view of water can also see that they're moving. They don't have conflicting information, and they don't have motion sickness (no cause, no effect). Meanwhile, the passengers in a cabin with no view (it's just four windowless walls), will feel their bodies moving but won't be able to see that they're moving. They have conflicting information, and they have motion sickness.

   Skill tested: Strengthen · how this choice captures the argument's function is the move to repeat next time.

   There's no common sense link between being an experienced airplane passenger and whether or not you have conflicting sensory information. People on planes presumably feel that they're moving (the plane vibrates and sometimes goes up and down from turbulence). A window seat would help the eyes also see movement, whereas an aisle seat might not be able to see movement. So there's potential for conflicting sensory info, but it depends on your seat, and this answer doesn't inform us where these people are sitting.

   Some automobile passengers whose inner ears indicate that they are moving and who have a clear view of the objects they

   These people feel that they're moving and can see they're moving but still get motion sickness. They don't have conflicting sensory information, and yet they're getting motion sickness. So this is a very mild weakener (because of "some") since it shows Effect w/o Cause.

   People who have aisle seats in trains or airplanes are as likely to get motion sickness as are

   Window seats allow people to see the motion that their bodies are feeling, whereas aisle seats generally don't allow people to see the motion their bodies are feeling. Since one group has conflicting sensory information and the other group doesn't, the author's hypothesis would predict that one group is more likely to get motion sickness than the other. So the fact that they're no different would weaken this hypothesis.

   Some astronauts do not get motion sickness even after being in orbit

   This is an extremely weak idea ("at least one astronaut"), so it's very unlikely to be correct on a Str / Wkn / Paradox question. This has no way of helping us to argue that conflicting sensory information causes motion sickness in astronauts. These astronauts aren't even getting motion sickness.
