87. A survey was recently conducted among ferry passengers on the North Sea. Among the results was this: more of those who had taken anti-seasickness medication before their trip reported symptoms of seasickness than those who had not taken such medication. It is clear, then, that despite claims by drug companies that clinical tests show the contrary, people would be better off not taking anti-seasickness medications.
Which one of the following, if true, would most weaken the conclusion above?
(A) Given rough enough weather, most ferry passengers will have some symptoms of seasickness.
(B) The clinical tests reported by the drug companies were conducted by the drug companies’ staffs.
(C) People who do not take anti-seasickness medication are just as likely to respond to a survey on seasickness as people who do.
(D) The seasickness symptoms of the people who took anti-seasickness medication would have been more severe had they not taken the medication.
(E) People who have spent money on anti-seasickness medication are less likely to admit symptoms of seasickness than those who have not.

Let's say you normally gain ten pounds after the holiday break.  By eating a drug, you only gained 2 pounds.  Would you be better off not taking the drug?  Of course not.  Therefore, choose answer D.

LS的解释很形象。
那些吃了药的人很可能本来就是那些容易晕机的人，他们即使吃了药也比其他人容易晕机，这一点不能说明药没有作用，因为，就像D所说，如果这些晕机的人不吃药，会晕得更厉害！所以D可以削弱吃药还不如不吃的结论。
