System of Government: Practice Questions & Explanations

There are 100 US Senators — two from each of the 50 states. This is set by Article I of the Constitution, which gives each state equal representation in the Senate regardless of population. Senators serve six-year terms, and elections are staggered so that roughly one-third of the Senate is up for election every two years. The Senate has unique powers including ratifying treaties (two-thirds majority required), confirming presidential appointments, and trying impeachment cases. The 435 figure refers to members of the House of Representatives, which is based on state population. The composition of the Senate is one of the central compromises of the Constitution: it balances the population-based House with equal state representation in the upper chamber.

Senators serve six-year terms. The Constitution sets the term length and staggers elections so that one-third of the Senate is up for election every two years. This staggered system means the Senate never turns over completely in a single election, providing institutional continuity. There is no constitutional limit on how many terms a Senator may serve, and many Senators have served for decades. By contrast, members of the House of Representatives serve two-year terms with all seats up for election simultaneously, and the President serves four-year terms with a two-term limit set by the 22nd Amendment. The longer Senate term was designed to give Senators more independence from immediate political pressure than House members.

The House of Representatives has 435 voting members. This number was set by the Reapportionment Act of 1929 and has not changed since. Each state's number of representatives is based on its population as measured by the census every ten years. The Constitution requires at least one representative per state, so the least populous states (Wyoming, Vermont, Alaska, North Dakota, South Dakota) have one each, while California has 52. Representatives serve two-year terms and all 435 seats are up for election in every even-numbered year. The 538 figure refers to the Electoral College, which includes 435 representatives plus 100 senators plus 3 electors for the District of Columbia.

US Representatives serve two-year terms. The Constitution sets this short term because the framers wanted the House to remain closely accountable to the people. All 435 House seats are up for election in every general election (every even-numbered year). There is no constitutional term limit. The Senate's six-year terms, by contrast, were designed to insulate Senators from short-term political pressure. The President's four-year term sits between the two. The combination of staggered terms across the branches was intended to slow rapid political change and force compromise.

The President of the United States is elected for a four-year term. The 22nd Amendment, ratified in 1951, limits a person to being elected President twice, for a maximum of eight years (or up to ten years if they assumed the presidency mid-term and served less than two years of the previous President's term). Before the 22nd Amendment, there was no constitutional limit, though all Presidents had voluntarily followed George Washington's two-term precedent until Franklin D. Roosevelt was elected four times. The presidential election occurs on the first Tuesday after the first Monday in November of years divisible by four. The President-elect is inaugurated on January 20th of the following year.

CHECKS AND BALANCES is the system by which each branch of the federal government has the power to limit or check the power of the other two branches, preventing any single branch from becoming too powerful. Both 'checks and balances' and 'separation of powers' are acceptable answers on the USCIS test. The Founders designed these systems based on their experience with unchecked governmental power (the British monarchy) and their study of political philosophy (Montesquieu's 'The Spirit of the Laws'). EXAMPLES of checks and balances: LEGISLATIVE checks on the EXECUTIVE: Congress can override a presidential veto with a 2/3 vote of both chambers; the Senate confirms presidential appointments and ratifies treaties; Congress can impeach and remove the president; Congress controls the budget. EXECUTIVE checks on the LEGISLATIVE: the President can veto bills passed by Congress; the President calls Congress into special session. JUDICIAL checks on both: the Supreme Court can declare laws or executive actions unconstitutional (judicial review). EXECUTIVE checks on the JUDICIAL: the President nominates federal judges including Supreme Court justices. LEGISLATIVE checks on the JUDICIAL: the Senate confirms judicial appointments; Congress can propose constitutional amendments to override court decisions; Congress sets the jurisdiction of lower federal courts. SEPARATION OF POWERS refers to dividing government into three distinct branches (legislative, executive, judicial) with different functions — each branch has its own authority and none can fully control the others.

The TENTH AMENDMENT to the Constitution establishes FEDERALISM by reserving to the states (or to the people) all powers not specifically granted to the federal government. USCIS Civics Question 45 asks for one power of the states. Acceptable answers: PROVIDE SCHOOLING AND EDUCATION; PROVIDE PROTECTION (police); PROVIDE SAFETY (fire departments); GIVE A DRIVER'S LICENSE; APPROVE ZONING AND LAND USE. Any one of these is correct. FEDERAL vs. STATE POWERS: ONLY FEDERAL: print money; declare war; create an army; make treaties with foreign nations; regulate interstate commerce. ONLY STATES: education; police; fire departments; driver's licenses; zoning/land use; marriage laws; most criminal law. SHARED (concurrent): taxation; building roads; making and enforcing laws; establishing courts. This division of power is called FEDERALISM — the constitutional system that balances power between the national government and the states. Debates about the proper scope of federal vs. state power have been present throughout American history (states' rights debates, Civil War, New Deal, civil rights era, and ongoing today). The system was designed to: keep government close to the people on local matters; allow states to serve as 'laboratories of democracy' experimenting with different policies; prevent concentration of all power at the national level.

The Supreme Court is the highest court in the United States. Its primary role is CONSTITUTIONAL INTERPRETATION — deciding whether laws and government actions comply with the Constitution. This is JUDICIAL REVIEW, established by Marbury v. Madison (1803). Nine Justices sit on the Supreme Court: one Chief Justice and eight Associate Justices. They are nominated by the President and confirmed by the Senate. They serve for LIFE (or until they resign or are removed). USCIS Question 39: 'What does the judicial branch do?' — Answer: reviews laws, explains laws, resolves disputes, decides if a law goes against the Constitution.

The U.S. Constitution has 27 AMENDMENTS. The first 10 amendments are the Bill of Rights (ratified 1791). The most recent, the 27th Amendment (concerning Congressional pay), was ratified in 1992. USCIS Civics Question: 'How many amendments does the Constitution have?' — Answer: twenty-seven (27). The amendments allow the Constitution to be changed over time; amending requires a proposal by two-thirds of both houses of Congress (or a constitutional convention) and ratification by three-fourths of the states.

The PRESIDENT is in charge of the EXECUTIVE BRANCH. The executive branch carries out and enforces federal laws. It includes the President, Vice President, the Cabinet, and federal agencies and departments. USCIS Civics Question: 'Who is in charge of the executive branch?' — Answer: the President. THE THREE BRANCHES: Legislative (Congress — makes laws); Executive (President — enforces laws); Judicial (courts — interprets laws). The President is both the head of state and head of government, as well as commander-in-chief of the military.

The two parts of Congress are the SENATE and the HOUSE OF REPRESENTATIVES. Together they form the bicameral (two-chamber) legislative branch. SENATE: 100 senators (2 per state), 6-year terms; HOUSE OF REPRESENTATIVES: 435 voting members, based on state population, 2-year terms; USCIS Civics Question: 'What are the two parts of the U.S. Congress?' — Answer: the Senate and House (of Representatives). Both chambers must pass a bill for it to become law (after the President signs it or a veto is overridden). The bicameral structure was a compromise (the Great Compromise) balancing representation between large and small states.

There are 100 U.S. SENATORS — two from each of the 50 states. USCIS Civics Question: 'How many U.S. Senators are there?' — Answer: one hundred (100). Each state has equal representation in the Senate (2 senators each) regardless of population — this was part of the Great Compromise. Senators serve 6-year terms, with about one-third up for election every two years. Compare: the House of Representatives has 435 voting members, apportioned by state population.

A U.S. Senator is elected for 6 YEARS. USCIS Civics Question: 'We elect a U.S. Senator for how many years?' — Answer: six (6). Senate terms are staggered so that approximately one-third of the Senate is up for election every two years, providing continuity. TERM LENGTHS to know: U.S. Senator — 6 years; U.S. Representative — 2 years; President — 4 years (maximum two terms per the 22nd Amendment); these term lengths are common USCIS civics questions.

The JUDICIAL BRANCH: Reviews and explains laws; resolves disputes (disagreements); decides if a law goes against (is consistent with) the Constitution. USCIS Civics Question: 'What does the judicial branch do?' — Accepted answers: reviews laws; explains laws; resolves disputes (disagreements); decides if a law goes against the Constitution. The judicial branch includes the Supreme Court and the federal courts. JUDICIAL REVIEW (established in Marbury v. Madison, 1803) is the power to declare laws unconstitutional. The Supreme Court is the highest court, with 9 justices who serve for life.

The SUPREME COURT is the highest court in the United States. USCIS Civics Question: 'What is the highest court in the United States?' — Answer: the Supreme Court. It has 9 justices (1 Chief Justice and 8 Associate Justices), appointed by the President and confirmed by the Senate, who serve for life (during good behavior). The Supreme Court has the final say on questions of federal law and the Constitution; its decisions are binding on all lower courts. It can declare laws and executive actions unconstitutional (judicial review).

One term for the President is four (4) years. This is an official USCIS civics question. The President is elected to a four-year term and, under the Twenty-second Amendment, may be elected to no more than two terms (a maximum of eight years, with a narrow exception for a vice president who succeeds to the office). Presidential elections are held every four years. Distinguishing the four-year presidential term from the six-year Senate term and two-year House term is a commonly tested point on the civics exam.

The President is the Commander in Chief of the military. This is an official USCIS civics question. The Constitution places civilian control over the armed forces by designating the President — an elected civilian official — as their commander in chief. While military officers lead the forces operationally, ultimate command authority rests with the President. Congress, however, holds the power to declare war and to fund the military. The principle of civilian control of the military, embodied in the President's role as commander in chief, is an important system-of-government concept.
