Answer:
If Alpha specializes in growing apples and Beta specializes in growing oranges, they could both gain by specialization and trade.
Explanation:
A country has comparative advantage in production if it produces at a lower opportunity cost when compared to other countries. A country should specialise in the production of goods for which it has a comparative advantage
Alpha
Opportunity cost in producing oranges = 9/18 = 0.5 apples
Opportunity cost in producing applies = 18/9 = 2 oranges
Beta
Opportunity cost in producing oranges = 4 / 16 = 0.25
Opportunity cost in producing applies = 16/4 = 4 oranges
Alpha has an opportunity cost in the production of apples while beta has a comparative advantage in the production of oranges
Alpha should specialise in the production of apples
Beta should specialise in the production of oranges
