Concept:An outward shift of the production possibility curve (PPC) represents an increase in an economy's productive capacity, known as economic growth.
Explanation:The PPC shows the maximum output combinations an economy can produce with its available resources and technology.
When the curve shifts outwards to the right, the economy can now produce more of both goods than before.
This higher productive potential means the economy is experiencing growth.
It does not mean over-production, because production is still within the new attainable limits.
It also does not indicate inefficient or under-production, because the capacity itself has expanded.
So, the outward shift is a sign of economic expansion.
Answer:A. growth
