Human wants are insatiable because wants are

Step 1: Analyze the question The question asks why human wants are described as "insatiable." Insatiable means can never be fully satisfied.

Step 2: Explain the concept This is the basic economic problem of scarcity:

• Human wants are unlimited. Once one want is satisfied, another appears. A student who gets a phone wants a laptop, then data, then a better phone.
• Resources (means) are scarce. Money, time, land, labour and capital are limited in supply compared to what people want.

Because wants are unlimited and means are scarce, people must make choices, set a scale of preference, and bear an opportunity cost. This is the foundation of economics.

Step 3: Evaluate each option

• A. Wrong. It says wants are limited, which contradicts "insatiable."
• B. Wrong. Resources are not unlimited. If they were, there would be no scarcity.
• C. Wrong. Wants are not limited, and this option also does not describe the scarcity problem.
• D. Correct. Wants are unlimited, while the means to satisfy them are scarce.

Step 4: Answer The correct option is D.

Tip: Remember the phrase "Wants are unlimited, means are limited (scarce)." If an option says wants are limited, or resources are unlimited, eliminate it immediately. Scarcity is a very common WASSCE, NECO and JAMB topic, so keep this pair firmly in mind.
