The correct answer is B. They used land bridges

Explanation:

Most theories related to human development and expansion towards all continents claim humans first emerge in Africa and then migrate to different parts of the world including Europe, Asia, and America. Moreover, as it is estimated this occurred more than 20,000 years ago when there were no technologies such as automobiles, ships or airplanes, it is believed humans used land bridges, which are natural bridges between continents or different zones, to migrate from Africa to other continents. For example, the Bering land bridge that connected Asia and America was used for human groups to get to America. Thus, early people migrate out of Africa using land bridges.

The theory of comparative advantage is credited to :_______
Viefleur [7K]

The theory of comparative advantage is credited to David Ricardo.

<h3>What is Ricardo's theory of comparative advantage?</h3>

In economics, a comparative advantage occurs when a country can produce a good or service at a lower opportunity cost than another country.

The theory of comparative advantage is attributed to political economist David Ricardo, who wrote the book Principles of Political Economy and Taxation (1817).

Comparative advantage is a key principle in international trade and forms the basis of why free trade is beneficial to countries.

Eg; Consider two countries (China and the UAE) that use labor as an input to produce two goods: wine and cloth.

In China, one hour of a worker’s labor can produce either 5 cloths or 10 wines.

In the UAE, one hour of a worker’s labor can produce either 20 cloths or 15 wines.

The UAE enjoys an absolute advantage in the production of cloth and wine.
