Unit review questions
1. Read this supplied card: “A fictional market has most output in two firms.” A writer adds, “This one example proves that every person and society has the same experience.” Which revision keeps what the card supports?
Need a hint?
  • Find the defining action, direction, date, institution or resource in each note separately.
  • Keep the conclusion within the stated examples; do not add a universal ranking or unstated causal result.
2. Fictional value $300, tariff 5%, no other fees. Landed cost?
Need a hint?
  • Model landed cost = stated import value × (1 + tariff rate as a decimal).
  • Keep the stated units and operation order; show the substitution before evaluating.
3. Read this supplied card: “A fictional firm pays to change equipment.” A writer adds, “This one example proves that every person and society has the same experience.” Which revision keeps what the card supports?
Need a hint?
  • Find the defining action, direction, date, institution or resource in each note separately.
  • Keep the conclusion within the stated examples; do not add a universal ranking or unstated causal result.
4. Read this supplied card: “A fictional child and relatives sustain cross-border relationships.” A writer adds, “This one example proves that every person and society has the same experience.” Which revision keeps what the card supports?
Need a hint?
  • Find the defining action, direction, date, institution or resource in each note separately.
  • Keep the conclusion within the stated examples; do not add a universal ranking or unstated causal result.

Use the skills in a new task

Create a one-page illustrated or written guide to Global Interdependence and Economic Choices. Include one accurate explanation from each of its four lessons and one comparison or calculation. Identify the evidence or model boundary. The guide must use supplied information; no real interview, purchase, personal record or outside approval is required. Younger learners may dictate or draw with an adult reading aloud.

Work on paper or in your own document. Explain the choices you made.

  • Include an accurate point from each of the four named lessons.
  • Connect each explanation to a supplied fact, record or numerical input.
  • Show the reasoning in one comparison, sequence or calculation; do not provide only a label.
  • Distinguish historical facts from original fictional classroom examples and avoid invented quotations.
  • State one limitation and what additional evidence would answer it.
Compare with a model response

Supply Chains and Points of Failure: Shipping caps throughput at six in the stated period. Redundancy at another stage does not remove that bottleneck; improvements must target the limiting stage or change demand. Tariffs Landed Cost and Model Scope: Fictional import value $100, tariff 10%, no other fees. Calculate the tariff: $100 × 0.10 = $10. Add it to the value: $100 + $10 = $110 model landed cost. Reporting $10 would give only the tariff; subtracting it would reverse the stated operation. Transport and other fees are excluded, so this result is not a claim about an actual shipment or who bears the final economic burden. Trade Gains and Distribution Questions: The total rises by 20%, yet a group is worse off under the stated measure. Aggregate gain does not prove universal gain; examine distribution and adjustment costs separately. Migration Remittances and Social Connections: The transfer is a remittance and the contact a social connection. These do not determine legal status or every labor-market effect; those require distinct rules and evidence. The guide explains these supplied cases, not every person or place. To make a broader claim, we would need additional matching records or observations from the people, places and period concerned.

A different response can also meet the criteria. Compare the evidence and reasoning, rather than copying the wording.
