Explanation:

- Economic Growth (Option 1):

- A high level of physical capital (machinery, tools) boosts productivity.

- Human capital (skills, education) enhances workforce efficiency.

- Together, they drive economic growth by increasing output and innovation.

- Correct Answer: Economic growth is typically the result of investments in both physical and human capital.

- Population (Option 2):

- Not directly related. Higher capital doesn't necessarily increase population.

- Population may grow due to other factors like birth rate and migration.

- Inflation (Option 3):

- Usually linked to monetary factors, not directly to capital levels.

- High productivity can sometimes stabilize prices, reducing inflation.

- Poverty (Option 4):

- Higher capital can reduce poverty by creating jobs and increasing incomes.

- But not the main measure or result of capital levels.
