Can a country only have a absolute advantage in one area?

Yes, a country can have an absolute advantage in only one area, which means it can produce a particular good or service more efficiently than other countries. However, this does not prevent it from having comparative advantages in other areas or being less efficient in others. Countries often specialize in the production of goods where they hold an absolute advantage, leading to trade benefits and economic growth. Thus, while a country can Excel in one area, it might still engage in trade for other products where it is less efficient.
