Final Answer:
The Gran Chaco is an arid, hot plain where few people live. (Option D)
Step-by-step explanation:
The Gran Chaco is an arid, hot plain characterized by sparse vegetation and a challenging environment for habitation. Option D accurately identifies this region as a vast, dry plain with limited human settlement. The Gran Chaco spans parts of several South American countries, including Argentina, Paraguay, and Bolivia.
The Gran Chaco is a distinctive biome known for its extreme temperatures and low population density. It experiences arid conditions with high temperatures, making it a challenging environment for sustained human habitation. The sparse vegetation and harsh climate contribute to the limited human presence in this region. While the Guiana Highlands (Option A), Amazon Basin (Option B), and Brazilian Highlands (Option C) are significant geographical features in South America, they are not characterized by the arid and hot conditions associated with the Gran Chaco.
The accurate identification of the Gran Chaco in Option D highlights the importance of geographical knowledge in understanding the diverse landscapes and climates present in South America. (Option D)
