Scarcity Drives Economic Choices

Steps:

• Identify the core problem in economics: resources are limited while wants are unlimited.
• Recognize that this imbalance, called scarcity, forces decisions on allocation.
• Evaluate choices: finite resources directly cause the need for choices.
• Confirm B matches the definition of scarcity as the root of economic decision-making.

Why B is correct:

• Scarcity, defined as finite resources relative to unlimited wants, compels economic agents to prioritize and choose among alternatives.

Why the others are wrong:

• A: Needs and wants are unlimited, not limited; limits come from resources.
• C: Free goods are abundant and require no choices, unlike scarce ones.
• D: The market mechanism responds to choices but does not cause them.

Final answer: B
