The conclusion that can best be drawn using all of the statements is:

4. Countries have had to address a variety of economic and social problems.

Explanation:

The problems and actions described in each sentence have different causes and different consequences. China implemented the one-child policy, for instance, because population growth was happening too rapidly. This is a different issue than the one addressed by the African nations. In this case, it is not about increasing or decreasing population growth, but about offering people the basic services a government should provide such as health care and education. When it comes to the Latin American nations, it is a matter of security. With that in mind, we can choose number 4 as the best Countries have had to address a variety of economic and social problems.
