Answer to Question 1

B

Answer to Question 2

In early stages of the transition, population growth will be rapid, and the need to create jobs will be great, so unemployment is a danger. Later on, the dependency ratio will rise as older people become a greater percentage of the population. The implications of these changes should be spelled out.
