Question

why might some countries limit the use of certain natural resources?
a to encourage additional fossil fuel use
b to raise the prices of imported goods
c to reduce the need for foreign trade
d to conserve supplies for future needs

Explanation:

Natural resources are finite. Limiting their use can ensure they are available for future generations. Options A (encouraging fossil fuel use would deplete resources), B (raising import prices is not the main reason for limiting resource use), and C (reducing foreign trade need is not the core motivation) are less relevant compared to conservation for future needs.

Answer:

D. to conserve supplies for future needs
