These two countries best represent the concept of globalization.

canada and the u. s
greenland and canada
mexico and the u. s.
the u. s. and greenland

The correct answer is - Canada and the U.S.

The North American countries of Canada and the United States are a perfect example of globalization. The border of the countries is more of a formality, people can move freely from one country to another, and also the economic activities are not charged on the border between them. The economies of the two countries are heavily connected and supportive between each other, and they are also dependent from one another. Migration between the two countries is very easy and without any problem (in normal circumstances of course).
