What term describes the practice of an individual, business, region, or country focusing its resources on producing a limited range of goods or services?

Explanation

Specialization refers to the concentration of resources by an individual, firm, region, or nation on producing a narrow set of goods or services. This is different from speculation, which involves risk-taking in markets; an overpass, which is a type of road structure; and capital flight, which is the rapid movement of assets out of a country.
