6. Women make up the majority of the population in the
country, and many of the prescriptions written by
doctors for tranquilizers are for women patients. The
testing of these drugs for efficacy and the calibration
of recommended doses, however, was done only on
men. Not even the animals used to test toxicity were
female.
The statements above, if true, best support which of
the following as a conclusion?
(A) Some tranquilizers are more appropriately pre-
scribed for women than for men.
(B) There have been no reports of negative side
effects from prescribed tranquilizers in women
(C) Tranquilizers are prescribed for patients in some
instances when doctors do not feel confident of
their diagnoses.
(D) The toxicity of drugs to women is less than the
toxicity of the same drugs to men.
(E) Whether the recommended dosages of tranquil-
izers are optimal for women is not known.

额~我知道楼主为啥选D。注意题目让选的是conclusion，不是assumption~~！！
女人们都没有参加对比试验，怎么会比出来毒性大小？
E的解释是：正因为每次都是抓男壮丁做小白鼠，所以试验ok了拿给妹子们吃。妹子即便有效果也不一定说明这个量就是最适合妹子的啊~
