Why was it difficult for large civilizations in Mesoamerica and South America to hold together?(1 point)

Answer 1

One reason it was difficult for large civilizations in Mesoamerica and South America to hold together was due to the lack of effective communication and transportation networks. These civilizations spanned vast territories with diverse geographical and ecological features, making it challenging to maintain efficient communication and transportation between different regions. This hindered the centralization of power and control, leading to the fragmentation and eventual decline of these civilizations.
