The correct option is (c).
Explanation
The Amazon Basin, located in South America, is dominated by the Amazon Rainforest. The inhabitants of this region have adapted their settlement patterns and housing structures to the hot, humid climate and dense vegetation of the tropical evergreen forest.
- Statement 1 is Incorrect: Beehive-shaped thatched houses are not absent in the Amazon Basin. In fact, some indigenous communities in the region live in thatched houses shaped like beehives. These are traditional dwellings constructed using locally available materials.
- Statement 2 is Correct: There are large, apartment-like communal houses known as "Maloca" found in the Amazon Basin. These structures are characterized by steeply slanting roofs. The steep slope is a necessary architectural adaptation to ensure that heavy tropical rains drain off quickly, preventing water accumulation and structural damage.
- Statement 3 is Correct: The Amazon Basin is home to the world's largest rainforest, providing an abundance of timber. Consequently, wood obtained from the rainforests is the primary material used for constructing houses and other structures in the region.
Key Takeaway: Housing in the Amazon Basin includes both small beehive-shaped thatched huts and large communal structures called "Malocas," which feature steep roofs to withstand heavy equatorial rainfall.
