검증된 단계별 안내1
Understand the concept of scarcity in economics: scarcity means that resources are limited while human wants are unlimited.
Recognize that because resources are limited, choosing one option means giving up another; this is the essence of a trade-off.
Define a trade-off as the need to sacrifice one thing to gain something else due to limited resources.
Contrast trade-off with other options: a free good is not scarce, surplus refers to excess supply, and market equilibrium is where supply equals demand.
Conclude that every decision involves a trade-off because scarcity forces individuals and societies to make choices between alternatives.
