Global Challenges & Historical Inquiry — Chapter Practice, Grade 10
Five focused units, followed by an evidence workshop, chapter review, and chapter quiz.
Problem 1
Answer and explanation
State the definition, period, and coverage before interpreting a total. Migration, displacement, and a particular legal category are not interchangeable. A border statistic cannot establish every person’s motive, rights, or current status without additional evidence.
Problem 2
Answer and explanation
Identify the person’s alternatives and the institutions shaping them. A move can reflect agency under constraint rather than either complete freedom or total passivity. Do not infer one motive from language, religion, or place of birth.
Problem 3
Answer and explanation
Separate transmission evidence from stereotypes about communities. A dated public-health account needs definitions, methods, and institutional context. Blaming a nationality does not explain a pathogen or demonstrate how resources and policies affected access.
Problem 4
Answer and explanation
Compare the denominator, date, place, method, and delivery chain. Distinguish the need assessed, resources sent, and services actually received. Public-policy judgment needs these connections rather than a dramatic image or aggregate total alone.
Problem 5
Answer and explanation
The record represents 80 distinct people through 100 crossings. It cannot establish all migration, unrecorded routes, household circumstances, or motives. A count must be interpreted using its unit, coverage, and period.
Calculate 20 × 2 + 60 = 100 crossings.
Count 20 + 60 = 80 distinct recorded people.
Identify omitted routes 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
Check package contents, recipients, duplication, delivery, household size, assessed needs, and actual access. Dispatch totals are not equivalent to people served or a measure of all unmet need.
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
Distinguish background, trigger, perpetrators, targets, and mechanisms. Categories did not make violence inevitable. Identify specific officials, militias, propaganda, and acts rather than assigning guilt or a fixed attitude to all Hutu people.
Problem 8
Answer and explanation
Date the event and identify the responsible forces and targeted population. A safe-area designation did not establish effective protection. The crime’s documented character does not require treating denial as equally supported historical interpretation.
Problem 9
Answer and explanation
Compare evidence of warning, capacity, decisions, and consequences. Distinguish lack of information from refusal to act or inadequate resources. Evaluate particular responsibility without making a blanket claim that institutions can never prevent harm.
Problem 10
Answer and explanation
Identify what the finding establishes and which questions remain outside it. Accountability, acknowledgment, repair, prevention, and social recovery are different outcomes. A conviction does not itself restore every victim’s loss or end all community disagreement.
Problem 11
Answer and explanation
A designation establishes an institutional claim, while effective protection requires capacity and decisions. Responsibility needs evidence about warnings, authority, available resources, orders, and actions. The scenario illustrates a mechanism without establishing every historical official’s knowledge or choices.
Identify the promise or designation.
Assess mandate, resources, and command decisions.
Compare warnings and actual actions.
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
No. A finding concerns specified conduct and responsibility under evidence and procedure. National identity does not establish individual guilt, and broader historical claims require their own records.
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
Identify the activity, mechanism, affected people, and measure. A total emissions figure and a per-person rate answer different questions. Neither alone establishes every actor’s historical responsibility or practical ability to reduce harm.
Problem 14
Answer and explanation
State the benefit, burden, period, and alternative. Explain institutions and resources rather than assuming development and environmental protection have one universal trade-off. Compare the distribution of effects within societies as well as between them.
Problem 15
Answer and explanation
Identify adoption, participation, implementation, and outcomes separately. An agreement’s existence is evidence of institutional cooperation, not proof that every goal has been met. Historical analysis should read the relevant dated text rather than infer present rules from a lesson summary.
Problem 16
Answer and explanation
State assumptions and compare alternatives using consistent criteria. Scientific evidence about a mechanism and a value judgment about distributing costs are distinct. Students can evaluate options without being required to adopt one prescribed political position.
Problem 17
Answer and explanation
B has the larger total, while A has the larger per-person rate. The measures answer different questions. A policy judgment also needs historical contributions, capacities, needs, distribution, and feasible alternatives, not a single number or assumed collective blame.
Compute 10 units per person for A.
Compute 4 units per person for B.
Identify missing histories, resources, and alternatives.
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. The projection depends on assumptions and implementation. Compare actual policy, measured outcomes, and other conditions before describing a forecast as an observed historical result.
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
Separate assets, debt, equity, and access to cash. A paper valuation, a loss, and an inability to meet immediate payments are related but different conditions. Explain the balance-sheet mechanism without treating every financial firm as having the same risk.
Problem 20
Answer and explanation
Identify the instrument, exposure, and channel transmitting a shock. Selling a claim can transfer some risk while creating or retaining other connections. A product’s rating or label is not proof that every holder understood or avoided losses.
Problem 21
Answer and explanation
Explain the feedback mechanism and the relevant period. A falling market index is one indicator, not a full measure of hardship. Compare employment, output, access to credit, household losses, and regional differences.
Problem 22
Answer and explanation
Evaluate a specific measure using authority, timing, scale, implementation, distribution, and alternatives. A recovery following a policy does not alone quantify its effect. Compare mechanisms and other conditions rather than assuming one preferred policy explains the whole result.
Problem 23
Answer and explanation
Equity falls from 10 to 5, a 50 percent loss after a 5 percent asset decline. The example illustrates leverage. It omits income, other assets, funding terms, and policy responses and does not describe a particular firm or offer an investment recommendation.
Compute 95 − 90 = 5 units of equity.
Compute (10 − 5) ÷ 10 = 50 percent loss.
Distinguish this simplified valuation from an entire institution.
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
No. Compare each measure’s mechanism, timing, implementation, and evidence while considering other conditions. Sequence alone cannot isolate one policy’s effect or establish a complete counterfactual.
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
State the time, place, criterion, and scope before drafting. Comparable cases need not be identical, but they should illuminate the same question. A bounded inquiry permits a qualified conclusion rather than demanding a verdict about entire civilizations.
Problem 26
Answer and explanation
Connect each item to a specific claim and note what it cannot establish. Two copied reports are not independent evidence. A quotation without explanation does not demonstrate reasoning, and an illustrative calculation cannot be presented as historical population data.
Problem 27
Answer and explanation
Use a causal chain rather than asserting that one event was good or bad. Acknowledge when evidence supports association more strongly than causation. A qualified claim can be more accurate and persuasive than an absolute conclusion unsupported by the sources.
Problem 28
Answer and explanation
Evaluate accuracy, relevant evidence, explained mechanisms, and limitations. A defensible alternative conclusion can earn full credit. Political, religious, or cultural agreement with a parent is not an assessment criterion, while stereotypes and factual errors still require correction.
Problem 29
Answer and explanation
A provisional thesis is that written changes can enlarge participation, while eligibility, enforcement, resources, and security shape practical access. The cases differ in setting and cannot establish one universal sequence. Use specific documents and institutions, and identify additional records needed to assess each group’s experience.
Define the dated institutions and eligibility.
Connect each change to implementation evidence.
Distinguish genuine gains from claims of universal access.
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. Credit accurate context, relevant evidence, an explained comparison, and acknowledged limits. The conclusion can differ if supported; ask for correction only where reasoning, evidence, or scope is inaccurate.
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.
