The central problem of economics is to satisfy the people's and nation's wants.

The problem we faced with is that our resources, here identified as money are __50__. The only way we can solve the problem is to make choices. After looking at our resources, we must examine our list of __51__ and identify the things we need immediately, those we can postpone, and __52__ we cannot afford. As individuals, we face the central problem involved in economics---deciding how to allocate(分配) our limited resources to provide __53__ with greatest satisfaction of our wants.

Nations face the same problem. As a country's population __54__, the need for more goods and services grows correspondingly. Resources necessary to production may increase, but there are __55__ enough resources to satisfy the total desires of a nation. Whether the budget meeting is taking place in the family living room, in the conference room of the corporation __56__ of directors, or in the chamber of the House of Representatives in Washington, the basic problem still exists. We need to find __57__ of allocating（分配） limited resources in order to satisfy unlimited wants.

A short time ago, economists divided goods into two categories, free and economic. The former, like air and water, were in __58__ abundance(丰富) that economists had___59____ them. After all, economics is the __60__ of scarcity and what to do about it. Today many of these "free goods" are __61_ very expensive to use. Population has made clean air and water expensive for producers extra cost, and __62__ taxpayers who pay for the government's involvement in cleaning the environment.

In the 1990s, almost all goods are __63__. Only by effort and money can they be obtained .

Meeting needs of people and the demands from resource available __64__ the basic activity of production. In trying to meet unlimited wants from limited economic goods, production leads to new problems in economics.
