Below are sample questions representative of the exercises included on this worksheet and related 9.31 Historical Thinking Sourcing, Contextualization, and Corroboration skill assessments:

Problem 1Difficulty: Mastery

Which interpretation is MOST consistent with corroboration and contextualization?

AThe press release must be correct because it uses a percentage.

BThe surveys must be wrong because they are qualitative.

CThe cartoon alone proves wages fell exactly 12%.

DThe wage claim may be sensitive to how 'real wages' are calculated; changing the price index and shortages can make official gains look larger than lived purchasing power.

Solution & Explanation:Mastery corroboration checks definitions and measurement (index changes) and compares with household evidence. Context (shortages, rent) can explain why official indicators and lived experience diverge.

Problem 2Difficulty: Mastery

What is the BEST implication for historians using Document A?

AEditing proves the leader never wrote any letters at all.

BEdited collections are always more accurate than originals.

CThey must treat the published collection as mediated; corroborate with drafts and archival notes to reconstruct what was altered and why.

DThe existence of an editor means historians should ignore all letters.

Solution & Explanation:Provenance matters: publication can change meaning. Mastery sourcing checks editorial intervention and uses corroboration (drafts, notes) to assess authenticity and intent.

Problem 3Difficulty: Mastery

Which use of evidence BEST demonstrates corroboration and historical reasoning?

AUse only A because propaganda sources define what happened.

BUse B and D to test the brochure’s claims, then compare findings to C’s argument and assess whether regional variation explains differences.

CUse only C because historians replace the need for primary evidence.

DDiscard B because numbers cannot be interpreted historically.

Solution & Explanation:Mastery involves triangulating across genres: propaganda (A), administrative data (B), lived experience (D), and scholarly interpretation (C). Corroboration tests claims and then situates them within broader patterns.
