Answer:Please see below
Explanation:
Production possibility frontier refers to the various combination of goods that can be produced in a given amount of time with the given factors of production. The Production possibility Curve illustrates how a shift occurs and output generated using time, inputs, technology and resources available etc.
-- In a country, economic growth can be brought about by technological improvements which will cause the PPC to shift outwards to the right. A disaster will cause the PPC curve to shift inwards to the left, increment of resources will cause PPC to shift to the right while a decrease of resources will cause PPC to shift to the left
Using the idea given above of how the Production Possibility curve shifts, we can answer the questions below
A new technology is invented to produce more nfood grains in the country. ----->shifts PPC to the right-
The country is using all its resources efficiently.--->point on the original PPC-
Many of the country's young people died in an earthquake. --->shifts PPC to the left-
The country plans to produce goods that are not possible to produce with the available resources----->unattainable point-
