Objective: Identify the next best alternative that a choice gives up.
Activity: Choose one decision involving time or money. Name the realistic alternative you would choose next and explain what makes it valuable.
Objective: Distinguish a change in quantity from a shift in supply or demand.
Activity: Choose a familiar product and describe one event that could change demand and one event that could change supply. Predict the direction of price and quantity, then name one limitation.
Objective: Explain why slower inflation does not reverse earlier price increases.
Activity: Complete the free fixed basket activity, calculate both inflation rates, and explain the result without using the words better or worse.
Objective: Describe what broad output growth can show and what it cannot establish by itself.
Activity: Write two sentences about a period of growth. The first should describe the aggregate change. The second should name one household or industry experience the average could hide.
Objective: Separate total economic scale from average output per person.
Activity: Compare two fictional economies with different GDP and population totals. Calculate output per person, then list two facts the average still does not reveal.
Objective: Separate the legal customs payment from the eventual economic burden.
Activity: Trace a tariff from the border payment to a final buyer. Identify at least three people or businesses that could absorb part of the cost and explain why the final result needs evidence.

Name one choice created by the change and its next best alternative.
Use supply and demand, inflation, or growth to explain one possible mechanism.
Name one broad economic measure that could add context and one fact that measure cannot reveal.
Cite at least two publisher sources from the course and explain why the evidence does or does not establish cause.
Separate rates from levels, totals from averages, and payments from economic burdens.
Identify the publisher, period, unit, and coverage of each observation used.
Do not turn an example, correlation, or simplified model into a universal claim.
