3. Check the relationship: Confirm that the answer explains the direction, tradeoff, mechanism, or measurement rather than relying on an isolated term.

Correct answer: B

The correct answer is A good or service purchased from a producer in another country.

1. Identify the economic concept: Determine whether the question concerns scarcity, incentives, markets, production, macroeconomics, trade, policy, or data.
2. Use the evidence: Imports are purchases from abroad and are part of the trade and national accounts framework.
3. Check the relationship: Confirm that the answer explains the direction, tradeoff, mechanism, or measurement rather than relying on an isolated term.

1. Identify the economic concept: Determine whether the question concerns scarcity, incentives, markets, production, macroeconomics, trade, policy, or data.
2. Use the evidence: Exchange rates affect cross-border prices and incentives, with effects depending on direction and market conditions.

1. Identify the economic concept: Determine whether the question concerns scarcity, incentives, markets, production, macroeconomics, trade, policy, or data.
2. Use the evidence: Development is multidimensional and cannot be reduced to one indicator or one year of growth.
3. Check the relationship: Confirm that the answer explains the direction, tradeoff, mechanism, or measurement rather than relying on an isolated term.

Correct answer: B

The correct answer is It does not fully show distribution, unpaid work, health, environmental conditions, security, or quality of life.

1. Identify the economic concept: Determine whether the question concerns scarcity, incentives, markets, production, macroeconomics, trade, policy, or data.
2. Use the evidence: GDP per person is useful for comparisons but must be combined with other social, distributional, and environmental measures.
3. Check the relationship: Confirm that the answer explains the direction, tradeoff, mechanism, or measurement rather than relying on an isolated term.

Correct answer: C

The correct answer is A good that is difficult to exclude people from using and whose use by one person does not substantially reduce availability to others.

1. Identify the economic concept: Determine whether the question concerns scarcity, incentives, markets, production, macroeconomics, trade, policy, or data.
2. Use the evidence: Non-excludability and non-rivalry help explain why markets may underprovide some public goods.
3. Check the relationship: Confirm that the answer explains the direction, tradeoff, mechanism, or measurement rather than relying on an isolated term.

The correct answer is A cost imposed on people outside a transaction that is not fully reflected in the private price.

1. Identify the economic concept: Determine whether the question concerns scarcity, incentives, markets, production, macroeconomics, trade, policy, or data.
2. Use the evidence: Pollution can create social costs that private buyers and sellers may not include in their decisions.
3. Check the relationship: Confirm that the answer explains the direction, tradeoff, mechanism, or measurement rather than relying on an isolated term.

Correct answer: A

The correct answer is It compares expected benefits and costs while making assumptions, distribution, uncertainty, and alternatives explicit.

1. Identify the economic concept: Determine whether the question concerns scarcity, incentives, markets, production, macroeconomics, trade, policy, or data.
2. Use the evidence: Cost-benefit analysis structures a decision but depends on measurement choices, discounting, uncertainty, and distributional judgments.
3. Check the relationship: Confirm that the answer explains the direction, tradeoff, mechanism, or measurement rather than relying on an isolated term.

Correct answer: B

The correct answer is The relationship may be informative, but causation requires additional evidence about timing, mechanisms, controls, and alternative explanations.

1. Identify the economic concept: Determine whether the question concerns scarcity, incentives, markets, production, macroeconomics, trade, policy, or data.
2. Use the evidence: Economic data should be interpreted with definitions, context, research design, and caution about causal claims.
3. Check the relationship: Confirm that the answer explains the direction, tradeoff, mechanism, or measurement rather than relying on an isolated term.
