What this topic is asking
Topic 2.1 opens Unit 2 by describing Congress, the legislative branch created in Article I. The College Board wants you to know how the two chambers differ in structure, powers, and functions, and why the framers built a bicameral legislature. These differences explain everything Congress does in the topics that follow.
Why Congress is bicameral
The two-chamber design is deliberate friction. Because a bill must pass both houses in identical form, legislation is filtered through two bodies with different terms, sizes, and constituencies. This slows lawmaking but, as Federalist No. 51 argues, weakens the strong legislative branch by dividing it.
How the chambers differ
The contrast between the chambers is among the most tested content in Unit 2.
The unique powers of each chamber
Each chamber holds constitutional powers the other does not:
- House only: all revenue (tax) bills must originate in the House (Article I, Section 7); the House holds the sole power to impeach (formally accuse) federal officials.
- Senate only: the Senate confirms presidential appointments (cabinet, judges, ambassadors) and ratifies treaties (by two-thirds vote), and it conducts the trial of impeached officials, removing them on a two-thirds vote.
These distinct powers connect Congress to the other branches and are the levers for many of the checks studied later in the unit.
Why this matters for the exam
Knowing which chamber does what is essential for Concept Application scenarios (a confirmation, an impeachment, a revenue bill) and for Argument Essays on whether Congress's structure helps or hinders effective government.
Try this
Q1. Name two powers unique to the Senate. [Recall]
- Cue. Confirming presidential appointments and ratifying treaties (also trying impeachments).
Q2. Explain why the Senate is more deliberative than the House. [Short explanation]
- Cue. It is smaller, with longer six-year terms and rules allowing extended debate (the filibuster), insulating it from short-term public pressure.

AP 2018 (style)3 marksA bill to raise federal income taxes must begin in one chamber, while the confirmation of a cabinet official occurs in the other. A. Identify the chamber where revenue bills must originate. B. Explain one structural reason the Senate handles confirmations rather than the House. C. Explain how bicameralism slows the policymaking process.Show worked answer →
A Concept Application FRQ, 3 points (A, B, C).
A. Identify: the House of Representatives, where all revenue bills must originate (Article I, Section 7).
B. Explain: the Senate's smaller size, longer six-year terms, and role representing the states make it the deliberative chamber the framers entrusted with confirmations and treaties.
C. Explain bicameralism: a bill must pass both chambers in identical form, so two differently structured houses must agree, which slows and filters legislation.
Markers reward the correct origination rule and a structural (not vague) reason for the Senate's distinct role.
AP 2021 (style)6 marksDevelop an argument about whether the differences between the House and the Senate make Congress more or less effective as a lawmaking body. Use at least one piece of evidence from one of the following: the Constitution of the United States or Federalist No. 51. Provide a defensible thesis, evidence and reasoning, and a response to an opposing perspective.Show worked answer →
An Argument Essay FRQ, 6-point rubric.
Thesis (1): e.g. "The differences make Congress less efficient but more deliberative, improving the quality of law at the cost of speed."
Evidence (up to 3): the origination, confirmation, and treaty powers in Article I and II; Federalist No. 51 on dividing the legislature to weaken it.
Reasoning (1): explain how two chambers with different terms and constituencies filter hasty legislation.
Alternative perspective (1): concede that bicameralism causes gridlock, then argue deliberation is the framers' intended trade-off.
