every society, in order to meet the needs of it's people, has to answer three basic questions:

- what should we produce?

every country can't produce everything, no matter how rich their land is. it may be a matter of technology, resources or geographical conditions. so, these three questions must be resolved in order to get the most of the production of each land.

hope this !
