Answer:
Three preconditions of development are increased trade, improved transportation networks, and entrepreneurship.
Step-by-step explanation:
In the context of W. W. Rostow's preconditions of economic development, an economy begins to transition from a subsistence-based economy based on agriculture and barter where there is only limited amounts of capital into a society where there is increased specialization and increasing transportation networks in order to foment trade. Because people start to generate more income from trade and production surpluses, there is greater entrepreneurship and industriousness. Societies begin to trade primary products with other nations. At present, the notion of sustainable development is dominant in the literature and in development spheres like NGOs and International organizations. This entails some controls of population pressure and efficient, renewable uses of environmental resources.
