The correct options that match the scenarios with their effects on the Production Possibilities Curve are as follows -
A new technology is invented to produce more food grains in the country - Shifts PPC to the right
The country is using all its resources efficiently - Points 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 with the available resources - Unattainable point on the PPC.
So, the correct matches are 1-B, 2-A,3-D and 4-C.
What is a Production possibilities curve?
A production possibilities curve or PPC is a graphical representation of the quantity of two goods that can be produced to gain optimum output by using the limited resources available.
Invention of new technology will lead to increase in the quantity of production shifts the PPC to the right as there is an unexpected shift in the quantities produced.
When a country uses all its resources efficiently, it is the equilibrium point of the PPC and hence, it denotes the optimum level of quantity produced.
When a country is planning to produce with the available resources, it denotes that the point on the PPC is unattainable, as there will always be scarcity of resources in an ideal market.
A situation where the youth population dies in an earthquake represents a leftward shift in the PPC, as the manpower and resources which were already limited are even more decreased.
Hence, the correct matches as per the shifts on the PPC curve are as aforementioned as 1-B, 2-A,3-D and 4-C.
