AP U.S. Government & Politics · Unit A

Foundations of Government

Chapters 1–3, foundational documents, constitutional design, and federalism. The practice test uses application, comparison, source-analysis, and data questions—the formats in the MC Question Slides.

How to use this guide

First pass — arguments.
Learn what each document or case argues about power, not only its definition. Ask: who gains power, who loses it, and why?
Second pass — structures.
For a scenario, identify the constitutional tool: separation of powers, a clause, federalism, or a grant.
Third pass — test.
Answer in sets, check your reasoning, open a source on missed items, then retake only missed questions.

Core ideas: direct answers to the unit targets

Legitimacy comes from people.
Locke’s natural-rights and social-contract ideas appear in the Declaration: people create government to secure rights and may replace a government that becomes destructive.
Democracy can work in different ways.
Participatory theory favors broad direct involvement; pluralism expects competing groups to influence policy; elite theory warns that a small, advantaged group often dominates.
The Articles’ weakness mattered.
Congress could not tax individuals, regulate interstate commerce, or reliably enforce national decisions. Shays’s Rebellion made the practical cost visible.
The Constitution divides power on purpose.
Representation, bicameralism, separation of powers, checks and balances, and federalism prevent any one majority, branch, or level from controlling everything.

Required documents: argument → evidence → connection

Declaration of Independence
Natural rights and consent make authority legitimate; a destructive government can lose that legitimacy.
Articles of Confederation
A league of sovereign states with a deliberately weak national government; its failures motivated the Convention.
Brutus No. 1
Necessary and Proper plus Supremacy could consolidate power, weaken states, and threaten liberty in an extensive republic.
Federalist No. 51
“Ambition” should counteract ambition. Separate institutions, checks, and federalism provide double security.
Federalist No. 39
The Constitution is partly national and partly federal: national institutions coexist with state-based ratification and representation.
Gettysburg Address
Lincoln connects the Union to equality and government by the people, echoing the Declaration.

Federalism: the sequence to use on scenario questions

1. Identify the level.
Enumerated powers belong to Congress; reserved powers remain with states; concurrent powers are shared.
2. Identify the tool.
Commerce regulates interstate trade. Necessary and Proper supports implied means. Supremacy resolves conflict with valid federal law.
3. Identify the relationship.
Cooperative federalism uses grants and shared administration. Categorical grants narrow discretion; block grants broaden it; unfunded mandates require action without enough money.
4. Apply the cases.
McCulloch validates implied national powers and bars state interference. Lopez limits Commerce Clause authority over noneconomic activity insufficiently tied to interstate commerce.

75-question multiple-choice practice test

This is deliberately not a vocabulary-matching quiz. It mixes concept application, historical reasoning, comparison, source analysis, and quantitative reasoning. Each check explains the answer and links a source for follow-up.

Rapid review: say these distinctions out loud

Brutus vs. Madison: Brutus fears consolidation and distant representation; Madison expects divided institutions to control abuse.

Articles vs. Constitution: Articles preserve state sovereignty and lack enforcement; the Constitution gives national institutions enumerated powers and supremacy.

Necessary and Proper vs. Commerce: the first permits useful means to execute enumerated powers; the second is an enumerated power.

McCulloch vs. Lopez: McCulloch broadly supports implied power; Lopez limits a weak Commerce Clause claim.

Categorical vs. block grant: categorical = narrow purpose and conditions; block = broad area and more state discretion.

Dual vs. cooperative federalism: dual keeps spheres separate; cooperative mixes levels, often through funding and shared administration.

Popular sovereignty vs. republicanism: authority originates with people; they ordinarily exercise it through representatives.

Full Faith and Credit vs. Privileges and Immunities: recognize other states’ records/judgments vs. do not unreasonably discriminate against other states’ citizens.
