Question

how have people living in the deserts of southwest asia usually made their living? running high - tech office parks; mining ice from glaciers; herding animals and trading across deserts; growing rain - fed rice on steep terraces

Explanation:

In Southwest Asia's deserts, the environment is arid. High - tech office parks are not typical of desert living. There are no glaciers in these deserts for ice mining. Rain - fed rice on terraces is not suitable for desert conditions. Herding animals (like camels, goats) and trading across deserts (using desert routes) is a traditional and practical way for desert dwellers in Southwest Asia to make a living, as animals can survive in arid conditions and trading leverages desert travel routes.

C. Herding animals and trading across deserts
