Trade Networks, Empires & Disruption — Chapter Practice, Grade 9
Five focused units, followed by an evidence workshop, chapter review, and chapter quiz.
Problem 1
Answer and explanation
A distant object shows a connection but not necessarily direct travel between its origin and findspot. Investigate intermediate markets, dates, and routes. Goods, techniques, and people can move at different speeds and through different connections.
Problem 2
Answer and explanation
No empire made every route safe at all times. Compare the place, date, fees, and security arrangements in a particular account. A claim about easier travel should state a baseline and not erase conquest or burdens imposed on local populations.
Problem 3
Answer and explanation
Translation involves interpretation and adaptation, not only transporting unchanged words. A text’s presence does not identify every resident’s belief. Compare patrons, language, use, and manuscript dates to explain how ideas circulated in local settings.
Problem 4
Answer and explanation
Use the object’s production date and the date of its deposition separately. A later collection location is not an ancient trade destination. Material patterns across dated sites provide a stronger network claim than one object without context.
Problem 5
Answer and explanation
The goods show an A–B–C connection through intermediaries. Their presence at C does not prove that A’s trader reached C. The example also does not establish whether similar historical networks used these exact places or terms.
Trace each supplied transfer.
Distinguish connected exchange from direct travel.
Identify records needed to study price, risks, and motives.
Response criteria
- Describe the historical context and institutions accurately.
- Connect relevant evidence to an explained conclusion.
- Represent particular perspectives without stereotypes or invented testimony.
- Identify an evidentiary limitation or a distinction that qualifies the claim.
Problem 6
Answer and explanation
Not by itself. Establish its earlier provenance and deposition history. Modern collection location and manufacture date alone do not demonstrate how or when it moved between regions.
Response criteria
- Describe the historical context and institutions accurately.
- Connect relevant evidence to an explained conclusion.
- Represent particular perspectives without stereotypes or invented testimony.
- Identify an evidentiary limitation or a distinction that qualifies the claim.
Problem 7
Answer and explanation
Seasonal winds influence possible timing but do not guarantee a voyage’s success. Storms, currents, ship condition, political access, and human decisions matter. A route should be explained through a combination of environmental knowledge and institutions.
Problem 8
Answer and explanation
A port’s trade wealth does not establish equal prosperity among residents or independence from inland communities. Compare production, labor, taxation, and distribution. Maritime histories should include the people supplying goods and services as well as famous travelers.
Problem 9
Answer and explanation
Do not describe all maritime conversion as one peaceful process or infer that every port became uniform. Identify the period, actors, and mechanism. Shared vocabulary or architecture can document contact while preserving local agency and varied beliefs.
Problem 10
Answer and explanation
A state fleet’s scale or termination concerns one institution, not the entire ocean’s economy. Compare official voyages with other shipping and local networks. Avoid using a single expedition to rank all societies’ maritime abilities.
Problem 11
Answer and explanation
Waiting can create demand for services and sustained local relationships. The winds influence timing, while storage costs and local rules shape choices. This invented case illustrates a mechanism without establishing a universal historical voyage schedule.
Connect waiting time to wind conditions.
Identify lodging, storage, sales, and local contacts.
State other information needed to judge costs or safety.
Response criteria
- Describe the historical context and institutions accurately.
- Connect relevant evidence to an explained conclusion.
- Represent particular perspectives without stereotypes or invented testimony.
- Identify an evidentiary limitation or a distinction that qualifies the claim.
Problem 12
Answer and explanation
Describe his fleets’ arrival, diplomacy, exchange, and power within existing networks. The communities and navigation histories of those ports preceded the voyages and should not be erased.
Response criteria
- Describe the historical context and institutions accurately.
- Connect relevant evidence to an explained conclusion.
- Represent particular perspectives without stereotypes or invented testimony.
- Identify an evidentiary limitation or a distinction that qualifies the claim.
Problem 13
Answer and explanation
Describe the particular coalition and military arrangements rather than contrasting intelligent settled societies with disorganized outsiders. Pastoral and urban economies often exchanged goods and services. Their institutions differed without forming a hierarchy of human worth.
Problem 14
Answer and explanation
A ruler’s reputation does not replace evidence of a particular event. Name the city, date, account, and uncertainties. Recognizing commerce under later rule does not cancel the violence of conquest, and documenting violence does not establish identical outcomes everywhere.
Problem 15
Answer and explanation
One successor state’s policy should not stand for every Mongol government over centuries. Compare dated rules and local practice. A claim of toleration needs its scope and limits rather than becoming a flattering description of an entire people.
Problem 16
Answer and explanation
A network can facilitate valuable exchange and harmful effects through related connections. Identify the mechanism, actors, and evidence for each claim. The existence of trade does not prove that every transported person volunteered or every route transmitted disease in the same way.
Problem 17
Answer and explanation
Protected movement on one route does not establish peace everywhere or erase earlier destruction. A bounded claim can describe facilitated travel during a defined period while identifying coercion and unequal effects.
Separate conquest from later route administration.
Identify places and periods rather than one universal condition.
Seek traveler, tax, and local records to assess who benefited.
Response criteria
- Describe the historical context and institutions accurately.
- Connect relevant evidence to an explained conclusion.
- Represent particular perspectives without stereotypes or invented testimony.
- Identify an evidentiary limitation or a distinction that qualifies the claim.
Problem 18
Answer and explanation
No. An achievement can result from compelled movement. Describe both the work and the conditions of relocation rather than treating cultural transmission as evidence of consent.
Response criteria
- Describe the historical context and institutions accurately.
- Connect relevant evidence to an explained conclusion.
- Represent particular perspectives without stereotypes or invented testimony.
- Identify an evidentiary limitation or a distinction that qualifies the claim.
Problem 19
Answer and explanation
A pathogen finding at one site strengthens a specific claim, not every route or transmission mechanism. Combine dated genetic, historical, and ecological evidence. Avoid asserting that all Chinese or African regions experienced identical effects when regional evidence differs.
Problem 20
Answer and explanation
State the region, period, source, and uncertainty when using a mortality estimate. A percentage calculated for one sample is not automatically continental mortality. Use comparable denominators and distinguish recorded deaths from inferred population loss.
Problem 21
Answer and explanation
Lack of modern microbiology does not mean no one observed patterns or tried practical responses. Explain an action through knowledge, resources, and institutions of its setting. Identify false blame and persecution as harm rather than treating prejudice as medical evidence.
Problem 22
Answer and explanation
Labor scarcity does not automatically end serfdom or cause the Renaissance. Explain the intervening institutions and compare regions where outcomes differed. A pandemic can contribute to change without being the single cause of every development afterward.
Problem 23
Answer and explanation
The registered sample yields 20 percent, but incomplete coverage and unknown migration prevent a secure whole-town estimate. More burial, household, and population evidence could improve the reconstruction. The invented figures are an exercise, not historical mortality data.
Compute 120 ÷ 600 = 20 percent.
Identify the missing residents and unrecorded migration.
Keep the denominator and limitations explicit.
Response criteria
- Describe the historical context and institutions accurately.
- Connect relevant evidence to an explained conclusion.
- Represent particular perspectives without stereotypes or invented testimony.
- Identify an evidentiary limitation or a distinction that qualifies the claim.
Problem 24
Answer and explanation
Compare regions, dates, labor rules, enforcement, and bargaining evidence. Scarcity could change opportunities while authorities reinforced obligations; one universal result is not established by population loss alone.
Response criteria
- Describe the historical context and institutions accurately.
- Connect relevant evidence to an explained conclusion.
- Represent particular perspectives without stereotypes or invented testimony.
- Identify an evidentiary limitation or a distinction that qualifies the claim.
Problem 25
Answer and explanation
A resource base creates possibilities rather than one automatic state form. Compare how an institution mobilized labor and income. Monumental water systems and port commerce require different evidence to assess administration and public effects.
Problem 26
Answer and explanation
Do not infer one sudden disappearance from an abandoned monument. Compare dated occupation, changing settlement centers, environmental evidence, and later communities. A capital’s changing role is different from the end of all Khmer history.
Problem 27
Answer and explanation
A useful explanation traces who adopted a practice, for what purpose, and how it changed locally. Similar forms are evidence to investigate, not proof of passive imitation. Cultural exchange may involve both cooperation and unequal political relationships.
Problem 28
Answer and explanation
A dynasty’s official emphasis does not establish that every household abandoned earlier practices. Compare court policy, religious institutions, texts, and local evidence. Period labels should locate change rather than freeze an entire population into one worldview.
Problem 29
Answer and explanation
Maintenance suggests ongoing institutional demands, while continued settlement challenges a claim of total disappearance. Neither establishes the complete cause of political change. More precise dates and evidence of labor, climate, and administration would help.
Separate maintenance needs from proof of a single collapse cause.
Identify continued settlement as a different question from royal authority.
Compare dating, environmental, and political evidence.
Response criteria
- Describe the historical context and institutions accurately.
- Connect relevant evidence to an explained conclusion.
- Represent particular perspectives without stereotypes or invented testimony.
- Identify an evidentiary limitation or a distinction that qualifies the claim.
Problem 30
Answer and explanation
No. Titles can be selected for legitimacy and adapted locally. Compare language, institutions, practice, and dates before making a claim about an entire population’s identity.
Response criteria
- Describe the historical context and institutions accurately.
- Connect relevant evidence to an explained conclusion.
- Represent particular perspectives without stereotypes or invented testimony.
- Identify an evidentiary limitation or a distinction that qualifies the claim.
