The state is beginning a new apprenticeship program for incarcerated individuals. Officials designed the program to improve the chances of inmates finding a job upon release and to increase the wages of these workers. To evaluate the program, researchers plan to measure incomes of inmates who participated and who did not participate one year after their release.

b. What limitations are associated with this type of research design?
