• C) imperfect methods of refining raw materials and creating capital

• D) always consumed all natural resources faster than they could replenish them

Imagine you're in a classroom with David, Charlotte, and Noah, and you're all learning about the theory of comparative advantage. If a nation has a comparative advantage in producing aircraft engines, what should it do?

• Specialize in the production of aircraft engines and trade for other goods/services

• Try to be self-sufficient in the production of ALL of the goods/services it needs

• Stop producing aircraft engines and import them from other countries

• Wait until it has an absolute advantage before producing aircraft engines

Answer explanation

A nation with a comparative advantage in aircraft engines should specialize in their production. This allows it to trade for other goods/services, maximizing efficiency and overall economic benefit.

Imagine you're at a Super Bowl party with Daniel, Priya, and Mia. Which of the following concepts best explains why we get less satisfaction the more we consume something? For example, we eagerly devour the first three slices of pizza, but then dread having it for leftovers the next night.

• Marginal utility

• TANSTAAFL

• Scarcity

• Future Consequences

Answer explanation

The concept of marginal utility explains that as we consume more of a good, the additional satisfaction (utility) we gain from each extra unit decreases. This is why the first slices of pizza are enjoyable, but later ones feel less satisfying.
