Answer: The correct answer is : Much of the Andean territory has arid conditions, especially in the east. The climate is also humid in the eastern part of the Central Andes.
On one side of the Andes mountain range is the Amazon jungle and on the other side is the desert coast. The Incas did not try to establish cities either in the jungle or in the desert, but it is believed that they entered and harvested fruits, seafood and wood.
