Answer to Question 1

ANS: C
Drug research was historically done only with white males, causing uncertainty as to the validity of the research results.

Answer to Question 2

ANS: B
In a double-blind study, neither the subject nor the health care provider knows which group the subjects are in. Since there is no difference in the appearance or packaging of the pills, the health care providers will not be aware of which subjects receive the experimental drug and which ones receive the placebo.
