Questions: When the demand for smartphones increased in Preteresia, a country in Eastern Europe, the smartphone manufacturers started importing silicon, a raw material used in the manufacture of smartphones, from Abresia, a country in Africa. In return, Preteresia helped build Abresia's infrastructure to facilitate the efficient extraction of silicon. This scenario best illustrates market segmentation monopolization global convergence centralization

The answer is: global convergence.

Explanation for each option:

1. Market segmentation: This refers to the process of dividing a broad consumer or business market into sub-groups of consumers based on some type of shared characteristics. The scenario described does not involve dividing the market into segments; rather, it involves international trade and cooperation.

2. Monopolization: This occurs when a single company or group gains exclusive control over a commodity or service, potentially leading to the elimination of competition. The scenario does not describe one entity gaining exclusive control over the smartphone market or silicon supply.

3. Global convergence: This term refers to the increasing interconnectedness and interdependence of countries, typically through trade, investment, technology, and cultural exchange. The scenario describes Preteresia and Abresia engaging in international trade and cooperation, with Preteresia importing silicon from Abresia and helping to build Abresia's infrastructure. This mutual exchange and collaboration are indicative of global convergence.

4. Centralization: This refers to the concentration of control and decision-making authority in a central organization or location. The scenario does not describe a centralization of control but rather a collaborative effort between two countries.

Therefore, the scenario best illustrates global convergence.
