College Board assigns Unit 2 · Networks of Exchange 8–10% of AP World History: Modern multiple-choice questions; this is not a percentage of the total exam score.
Silk Roads, Indian Ocean routes, and trans-Saharan corridors expanded through different transport ecologies while states, diasporas, credit, and commercial cities reduced risk and moved goods, ideas, organisms, and disease.
- Lens interregional exchange from c. 1200 to c. 1450
- Regions Central and East Asia, the Indian Ocean basin, North and sub-Saharan Africa, and Mediterranean interfaces
- Decision A student says all three networks expanded because merchants wanted luxury goods. What missing evidence best repairs the explanation?
What Unit 2 · Networks of Exchange connects
Treat a network as infrastructure plus institutions; a commodity list cannot explain why movement increased or why effects varied by region.

How the AP World History: Modern assesses Unit 2 · Networks of Exchange
The exam samples interregional exchange from c. 1200 to c. 1450 through sources and evidence-centered reasoning.
| Item | Weight / count | What it means |
|---|---|---|
| Multiple choice | 55 questions in 55 minutes | Forty percent; questions normally share historical stimuli. |
| Short answer | 3 required in 40 minutes | Twenty percent; each source-based question has three separately scored parts. |
| Document-based question | 7 documents; 60 recommended minutes | Twenty-five percent; evidence must become an argument. |
| Long essay | 1 required; 40 recommended minutes | Fifteen percent; the prompt supplies the choice structure. |
| Delivery | Fully digital in Bluebook | The coordinator confirms the location-specific Session 1 start time. |
| Tools | No calculator or subject reference | Chronology, evidence, and reasoning must be retrieved and applied. |

Practice 1: Explain why exchange networks expanded
A student argues that the Silk Roads, Indian Ocean routes, and trans-Saharan corridors all expanded from c. 1200 to c. 1450 only because merchants wanted luxury goods.
Which revision best strengthens the student's explanation?
A. Add a longer list of silk, spices, gold, and other traded commodities.
❌ Not quite 😭 A commodity list shows what moved but not why movement became easier or safer. It leaves transport and commercial institutions out of the causal explanation.

B. Compare one transport constraint in each network and explain how states, diasporas, or commercial institutions reduced it.
✅ Correct! 😊 This keeps the comparison consistent and supplies causal mechanisms. It also allows the networks to expand through different combinations of infrastructure, timing, protection, and trust.
C. Arrange the networks chronologically and treat later expansion as proof of merchant demand.
❌ Not quite 😭 Sequence alone does not prove causation. This choice still assumes demand caused expansion without explaining how merchants overcame environmental and political constraints.

D. Claim that all three networks produced identical cultural effects wherever they reached.
❌ Not quite 😭 Connectivity did not make societies culturally uniform. Local communities and institutions redirected imported practices, so this claim adds a new unsupported generalization.

Full explanation
- Step 1Identify the defect: merchant demand alone cannot explain how movement overcame transport, security, and trust problems.
- Step 2Hold the comparison constant by examining a constraint and a solution in each network.
- Step 3Connect solutions to institutions such as caravanserais, port diasporas, states, or commercial credit.
- Step 4Preserve regional variation because overland, maritime, and desert routes operated in different environments.
Practice 2: Distinguish movement from its effects
A source describes merchants timing voyages across the Indian Ocean to predictable seasonal winds and relying on resident trading communities in port cities.
(a) Identify one environmental factor reflected in the source. (b) Explain one way a commercial institution supported Indian Ocean exchange from c. 1200 to c. 1450. (c) Explain one reason increased connectivity did not produce identical cultural outcomes in every port.
A. Identify the monsoon system, explain how port diasporas created trusted relationships, and show how local communities adapted imported practices.
✅ Correct! 😊 This plan separates environment, commercial institution, and cultural variation. Each example is linked to the precise relationship requested.
B. Name spices for every part and conclude that valuable goods caused all changes.
❌ Not quite 😭 Spices are a commodity, not an environmental factor or institution. Reusing them cannot explain trust among merchants or variation in cultural adoption.

C. Describe ship design, list ports, and state that trade erased cultural differences.
❌ Not quite 😭 The list does not explain how an institution supported exchange. The conclusion also mistakes connection for uniformity and ignores local selection and adaptation.

D. Discuss the Silk Roads and Mongol protection without addressing the Indian Ocean source.
❌ Not quite 😭 Those facts concern another network and bypass the evidence in the prompt. A valid response must use the Indian Ocean setting and its seasonal and institutional mechanisms.

Full explanation
- Step 1Read the source for separate clues: seasonal winds are environmental, while resident merchant communities are institutional.
- Step 2Explain that predictable monsoons helped schedule voyages rather than merely naming the winds.
- Step 3Connect diasporic communities to information, credit, trust, or assistance in port cities.
- Step 4Explain cultural variation through local actors who translated, selected, or adapted imported practices.
