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.
