Which of the following is not a problem of overpopulation?

The answer is "inadequate workforce" because overpopulation usually results in an excess of labor supply, which can lead to unemployment, but not inadequate workforce. Inadequate workforce implies a shortage of people available to work, which is not a typical result of overpopulation. Overpopulation can lead to a rapid increase in population, which can cause various problems, such as the strain on resources, the decline in the standard of living, and the decline in the standard of health due to a lack of access to essential resources and services. Therefore, inadequate workforce is not a problem of overpopulation.
