Questions 1–30 · eight assessment parts · 40 points. Choose the form assigned by your teacher.
Form B uses shorter directions and clearer response cues. Academic content and points are the same.
Part I
Read the Evidence
Work like an archaeologist: context, observation, evidence, and responsible claims.
Read the cluesEvidence & Sources
Point X
Recorded layerBones nearbyDated hearth
Point Y
Disturbed soilNo recorded location
Why can Point X support a stronger archaeological claim?
Drag the best reason into the answer dock.
Nearby bones prove the exact activity.
Shape matters more than location.
Its context connects it to other evidence and dating information.
Missing context makes Point Y better for dating.

A student says ancient ocean boundaries must have looked exactly the same as modern coastlines. Which correction is best?
Drag the best correction into the answer dock.
A. Archaeologists do not use coastlines when studying migration.
B. Ancient people could travel only on land, so coastlines do not matter.
C. Modern coastlines show every Ice Age shoreline accurately.
D. Sea levels changed, so ancient coastlines could differ from today’s.

C
A community can build shelters but moves during different seasons to reach changing food and water sources. Which interpretation is most accurate?
Drag the strongest explanation into the dock.
A. Mobility can be an adaptive strategy for following resources and sharing risk.
B. Seasonal movement suggests the community had not learned to use permanent shelters effectively.
C. Moving between resource areas is useful only when a community has no food-storage knowledge.
D. Seasonal mobility makes long-term cooperation and social networks unlikely.
BEST EXPLANATION

Basketorganic material
Wood handleorganic material
Fiber netorganic material
A site preserves many stone tools but no baskets, wooden handles, or fiber nets. Which TWO conclusions are responsible?
Drag exactly two responsible conclusions into the docks.
A. The community definitely used only stone technology.
B. Organic technologies may have decayed more readily than stone.
C. Stone never survives in archaeological sites.
D. Surviving stone evidence may underrepresent the original variety of technology.

Which statement best avoids treating all foraging communities as one single way of life?
Drag the most accurate generalization into the dock.
A. Most foraging communities followed the same seasonal pattern because wild resources were similar everywhere.
B. Foraging communities varied in mobility, food, tools, settlement, and social organization.
C. Differences among foragers mainly reflected how close each group was to adopting farming.
D. Long-term shelters and complex tools were uncommon because mobility prevented both.

Distinguish cultivation, domestication, sedentism, surplus, and the many pathways toward agriculture.
Build the vocabulary systemConcepts & Academic Vocabulary

C. living mainly in one location
D. population change through selection and management across generations

Complete both statements with exact labels from the visual.
Revise an overclaimClaims & Historical Reasoning
⚖
Surplus creates possibilities, not guarantees.
Historical outcomes depend on institutions, labor, storage rules, local conditions, and who controls resources.
A student writes, “Once a community has surplus, hierarchy will happen.” Which revision is most responsible?
Use only what the schematic supportsEvidence & Source Analysis
Which THREE statements are directly supported by the schematic?
Select exactly three.
Observation or evidence limit?Evidence & Source Analysis
Stone artifact, Egypt
Mark O for OBSERVATION and L for an EVIDENCE LIMIT.
a. The image shows a long, narrow stone object with visible worked edges.
b. The artifact cannot by itself prove one exact use or reveal a whole culture without context.
