Answer to Question 1

ANS: B
A quasi-experimental design would have a nonmatched comparison group but no random assignment to a treatment group. Such quasi-experimental designs may contribute valuable information but ultimately lack the power to ascribe cause, because the variables are uncontrolled and potentially influential. Ethical decisions do not permit the use of this experimental design in all situations.

Answer to Question 2

ANS: C
This act has five provisions, one of which requires pediatric evaluation of new products intended for use by children. The act advocates for children and appropriate testing for drugs to be used by the pediatric population.
