Answer: Country B has created a slow-growing self-sufficient economy in the past decade.
Step-by-step explanation:
Recessions are periods of a downturn in Economic activity and as already mentioned lead to high unemployment and a reduction in consumer spending.
As Europe is suffering through a recession, any country that has linked its Economy to that of Europe will suffer as well. Countries E, A, D and C rely on patronage from European countries and so if consumer spending reduces in Europe as it has, the effect would be a reduction in patronage from Europe so these countries will see their economies suffer.
Country B will not be affected as they have built a self-sustaining economy which is called an Autarky. As a result, economic events outside their country will not affect them.
