Final answer:
Brazil is an example of a formal region, recognized by distinct governmental and administrative boundaries. It includes diverse landscapes and is an economic and cultural hub with global influence through events like Carnival and international sports competitions.
Step-by-step explanation:
The question refers to the types of regions and specifically asks which type of region Brazil exemplifies. There are three types of regions: formal, functional, and perceptual. Brazil is an example of a(n) formal region, as it has a governmental and administrative boundary recognized internationally, separating it from other countries. Within Brazil, there are other regions with unique characteristics contributing to the country's diverse landscape, such as the urban southeast, which forms the economic core, and the Amazon Basin in the northern peripheral region, known for its natural resources.
Brazil's large metropolitan areas are not only economic hubs but also cultural hotspots. Events like Carnival and international sports competitions like the FIFA World Cup showcase Brazil's socio-cultural influence worldwide.
