Answer: The correct answer is C: "Societies can encourage population growth."
Step-by-step explanation:
First of all, it is necessary to understand what scarcity is. Scarcity refers to the lack of resources to supply basic needs of specific society (city, state, country, etc). Those resources are essential to guarantee enough food, good sanitation services, and equal income for all population. For that reason, if a society is trying to solve the problem of scarcity CANNOT encourage population growth since with more population greater scarcity.
