Answer to Question 1

D

Answer to Question 2

Longitudinal studies test the same sample of participants repeatedly over a period of time. Weaknesses in this approach include cost, substantial research effort, participant test familiarity, and age-history confound. Its strengths include the ability to study the stability of human characteristics as well as to observe the process of development and the factors that precede or follow particular developmental phenomena.
