Answer to Question 1

ANS: B
The experimental design uses different groups of subjects (i.e., some groups who receive treatment and control groups who receive no treatment, an alternative treatment, or a combination of both), and assigns subjects randomly to treatment or control groups. Treatment groups and control groups do not differ in terms of baseline characteristics or demographics.

Answer to Question 2

ANS: A
The double-blind technique is a powerful tool wherein neither the healthcare provider or the subject knows whether the subject is receiving the experimental or control form of therapy.
