Developed countries are facing challenges because their populations are

a] aging due to decreased death rates.
b] increasing due to higher birth rates.
c] losing a sense of economic stability.
d] competing for limited natural resources.

{i chose d and i got it incorrect}

The correct answer is "A".

Developed populations, such as Japan and the Scandinavian Countries, are facing 2 current realities:

The first reality comes as a result of the improvement of living conditions and health services within these countries, which increases the life expectancy of citizens.

The second reality comes as a result of fewer citizens wanting to commit to family life and having children. This ideological shift has been going on for the last 20 years and is causing countries such as Sweden to promote foreign immigration in order to fulfill their labor needs.

when a country suffers, for example, a drought period, the market product is affected for a low offer, in this case, potatoes; the government has to tax to the households, which have to give more money for the potatoes which they consume, that situation make them consume substitute goods even through loans, it could increase the financial market movement and the inflationary phenomena, the business has to increase salaries in order to the employees could buy a more expensive food (potatoes) and in order to inflation tha business had to buy expensive supplies in the factor market, while the rest of the world have to gain more money to consume the same amount of potatoes.
