Answer:
Bellisima's opportunity cost:  
Production of rye per million hours of labor = 24 / 12 = 2 pairs of jeans
Production of jeans per million hours of labor = 12 / 24 = 0.5 bushels of rye
Dolorium's opportunity cost:  
Production of rye per million hours of labor = 32 / 8 = 4 pairs of jeans
Production of jeans per million hours of labor = 8 / 32 = 0.25 bushels of rye
Dolorium has a comparative advantage in the production of jeans while Bellisima has a comparative advantage in the production of rye.
If both countries specialize:
Bellisima will produce 48 million bushels of rye.
Dolorium will produce 128 million pairs of jeans.
Total production of rye has increased by 12 million bushels.
Total production of jeans has increased by 24 million pairs.
 
        
             
        
        
        
Answer:
Option (D) is correct.
Explanation:
Nominal variables are the variable which are calculated on the basis of current market prices such as nominal GDP. Nominal GDP incorporates all of the changes happened in a current year such as changes occured in the inflation or deflation in a current year.
On the other hand, real variables are those variables which are calculated on the basis of base year prices to take the effects of the inflation or deflation during the period of time. For example, Real GDP. real GDP is determined by the market prices of the base year, so that one can compare the actual effect effect of inflation or deflation during a period of time.
