Short Answer Causation and Continuity
This topic covers cause, effect, continuity, change over time, context, periodization, and historically defensible explanation.
How to study for AP U.S. History
Build every answer around period, source, context, evidence, and the historical reasoning process the prompt actually asks for.
Core concepts
Concept 1
Short Answer Causation and Continuity questions test AP U.S. History content through historical thinking, source analysis, context, and argumentation.
Exam cue: Name the task: developments and processes, sourcing, claims and evidence, contextualization, making connections, or argumentation.
Concept 2
The strongest answer identifies the period, source point of view, historical development, reasoning process, and evidence demanded by the prompt.
Exam cue: Check chronology, region, audience, purpose, point of view, historical context, and whether the item asks for comparison, causation, or continuity and change.
Concept 3
Eliminate choices that are plausible history statements but miss the time frame, source, causation, comparison, continuity, or claim being tested.
Exam cue: Use specific evidence and historical reasoning rather than broad labels or present-day assumptions.
