1. The Basic Economic Problem and Opportunity Cost | 基本经济问题与机会成本
The core of economics starts with the basic economic problem: unlimited wants versus limited resources. This creates scarcity and forces us to make choices, which always involve an opportunity cost.
经济学的核心始自基本经济问题：无限的欲望与有限的资源。这导致了稀缺性，迫使我们做出选择，而任何选择都涉及机会成本。
Scarcity: The condition where there are insufficient resources to satisfy all human wants and needs.
稀缺性：资源不足以满足所有人类欲望和需求的状态。
Choice: The decision made between alternative uses of scarce resources.
选择：在稀缺资源的多种用途之间做出的决定。

2. Factors of Production | 生产要素
To produce goods and services in any economy, we rely on four factors of production. Understanding these factors and their rewards helps explain how economies create wealth.

资本：用于生产其他商品和服务的人造物品，如机器、工具和建筑物。资本的报酬是利息。
Enterprise: The willingness and ability to combine the other three factors to produce goods and services, taking risks. The reward is profit.
企业家精神：将其他三种要素结合起来生产商品和服务并承担风险的意愿和能力。其报酬是利润。
