Hello, you have not informed the answer options, which makes it impossible for your question to be answered with specificity. However, one possible reason that influenced the cultural change of South America, making it a global travel and trade destination, was the exploitation of natural resources and the expansion and exploitation of cultural diversity.
Most of South America has tropical countries, which means that these countries have abundant natural resources for most of the year. The exploitation of these resources stimulated the expansion of international commercial relations, providing a great territory of raw material for countries that do not have this same privilege, which made South America a desirable place to trade. In addition, since it was colonized by different countries, the South American countries began to explore their cultural diversity, showing a warm and welcoming image, which made these countries a good place for travel, thus stimulating local tourism.
