FSOT Flashcards

Three branches of the U.S. government

Legislative (Congress — makes laws), Executive (President — enforces laws), and Judicial (the courts — interprets laws). The Constitution separates these powers and balances them through checks and balances.

Checks and balances

The system by which each branch of government can limit the powers of the others — e.g., the President vetoes bills, Congress overrides vetoes and confirms appointments, and the courts can rule actions unconstitutional.

Separation of powers

The division of government into legislative, executive, and judicial branches so that no single branch holds all power. It is a foundational principle of the U.S. Constitution.

Federalism

The division of power between a national (federal) government and state governments, each with its own areas of authority. Some powers are shared (concurrent) and some are reserved to the states.

Bill of Rights

The first ten amendments to the U.S. Constitution (ratified 1791), guaranteeing rights such as free speech, religion, and press (1st), the right to bear arms (2nd), and due process (5th).

First Amendment

Protects five freedoms: religion, speech, press, assembly, and petition. It bars Congress from establishing a religion or abridging free expression.

How a bill becomes a law (federal)

A bill is introduced in the House or Senate, passes committee, is approved by both chambers in identical form, then is signed by the President — or becomes law over a veto by a two-thirds vote in each chamber.

Marbury v. Madison (1803)

The Supreme Court case that established judicial review — the power of the courts to declare a law or executive action unconstitutional. It made the judiciary a co-equal branch.

Declaration of Independence (1776)

Drafted primarily by Thomas Jefferson, it declared the thirteen colonies independent of Britain and asserted that all people have unalienable rights to life, liberty, and the pursuit of happiness.

U.S. Constitution

Ratified in 1788, it is the supreme law of the United States. It creates the three branches, divides power between federal and state governments, and can be amended (27 amendments to date).

Monroe Doctrine (1823)

A U.S. foreign-policy statement opposing further European colonization or intervention in the Western Hemisphere, while pledging U.S. non-interference in existing European colonies and European affairs.

Truman Doctrine (1947)

U.S. policy to provide political, military, and economic aid to nations threatened by communism. It launched the Cold War strategy of containment.

Marshall Plan

The U.S. program (1948) that gave billions in aid to rebuild Western European economies after World War II, partly to resist the spread of communism.

Containment

The Cold War U.S. strategy of preventing the spread of communism beyond its existing borders, articulated by diplomat George Kennan and enacted through the Truman Doctrine, NATO, and other policies.

Emancipation Proclamation (1863)

President Abraham Lincoln's order declaring enslaved people in Confederate-held territory to be free. It reframed the Civil War as a fight against slavery.

Civil Rights Act of 1964

Landmark U.S. law that outlawed discrimination based on race, color, religion, sex, or national origin and ended segregation in public places.

The amendment process

An amendment to the U.S. Constitution is proposed by a two-thirds vote of both houses of Congress (or a national convention) and ratified by three-fourths of the states.

Electoral College

The body that formally elects the U.S. President. Each state's electors equal its members of Congress; a candidate needs 270 of 538 electoral votes to win.

Powers of Congress

Enumerated in Article I: to tax, borrow, regulate interstate and foreign commerce, declare war, raise armies, coin money, and make laws 'necessary and proper' to carry out its duties.

Roles of the U.S. Secretary of State

The Secretary of State is the President's chief foreign-affairs adviser and head of the Department of State, leading U.S. diplomacy, negotiating treaties, and directing the Foreign Service.

Treaty of Westphalia (1648)

Ended the Thirty Years' War and is widely seen as the origin of the modern system of sovereign nation-states, establishing the principle of state sovereignty.

Treaty of Tordesillas (1494)

An agreement between Spain and Portugal, mediated by the Pope, dividing newly discovered lands outside Europe between them along a meridian west of the Cape Verde Islands.

Treaty of Versailles (1919)

Ended World War I, imposed reparations and territorial losses on Germany, and created the League of Nations. Its harsh terms are often linked to the rise of World War II.

The United Nations

Founded in 1945 to maintain international peace and security. Its principal organs include the General Assembly and the Security Council (five permanent members with veto power: U.S., U.K., France, Russia, China).

NATO

The North Atlantic Treaty Organization (1949), a collective-defense alliance in which an armed attack against one member is considered an attack against all (Article 5).

The Cold War

The period of geopolitical rivalry (roughly 1947–1991) between the U.S.-led Western bloc and the Soviet-led Eastern bloc, marked by an arms race, proxy wars, and ideological competition rather than direct war.

Non-Aligned Movement

A group of states, founded during the Cold War, that chose not to formally align with either the U.S. or the Soviet bloc, seeking to preserve their independence and sovereignty.

Decolonization

The process, peaking after World War II, by which colonies in Africa, Asia, and elsewhere gained independence from European powers, reshaping the modern map and the membership of the United Nations.

Latitude vs. longitude

Latitude lines run east–west and measure distance north or south of the Equator; longitude lines run north–south and measure distance east or west of the Prime Meridian.

The Equator and Prime Meridian

The Equator is 0° latitude, dividing Earth into Northern and Southern Hemispheres; the Prime Meridian is 0° longitude (through Greenwich), dividing it into Eastern and Western Hemispheres.

The seven continents

Africa, Antarctica, Asia, Australia, Europe, North America, and South America. Asia is the largest by area and population.

Bretton Woods system

The post–World War II international monetary framework (1944) that created the International Monetary Fund (IMF) and the World Bank and pegged currencies to the U.S. dollar.

The Suez Crisis (1956)

A conflict over Egypt's nationalization of the Suez Canal, in which Britain, France, and Israel intervened militarily but withdrew under U.S. and Soviet pressure — a marker of the decline of European colonial power.

The European Union

A political and economic union of European states that allows free movement of goods, services, capital, and people; many members share the euro currency.

The Industrial Revolution

The transition (beginning in late-18th-century Britain) to machine-based manufacturing, which transformed economies, urbanized populations, and reshaped global trade and power.

Supply and demand

The model in which the price of a good is set where the quantity buyers want (demand) equals the quantity sellers offer (supply). Price rises when demand exceeds supply and falls when supply exceeds demand.

Gross Domestic Product (GDP)

The total market value of all final goods and services produced within a country in a given period — the broadest measure of an economy's size and output.

Inflation

A sustained rise in the general price level, which reduces the purchasing power of money. It is commonly measured by the Consumer Price Index (CPI).

Fiscal policy vs. monetary policy

Fiscal policy is the government's use of taxing and spending to influence the economy; monetary policy is the central bank's control of the money supply and interest rates.

The Federal Reserve

The central bank of the United States. It conducts monetary policy by setting interest-rate targets, regulating banks, and managing the money supply to promote stable prices and employment.

Comparative advantage

The principle that a country should specialize in producing what it can make at the lowest opportunity cost and trade for the rest — the economic basis for the gains from international trade.

Opportunity cost

The value of the next-best alternative given up when a choice is made. Every economic decision has an opportunity cost because resources are scarce.

Tariff

A tax on imported goods. Tariffs raise the price of imports to protect domestic industries or raise revenue, but they can reduce overall trade and raise consumer prices.

Most Favored Nation (MFN) status

A trade principle requiring a country to extend any trade advantage (such as a low tariff) granted to one trading partner to all other partners, ensuring non-discriminatory trade.

Free trade vs. protectionism

Free trade removes barriers (tariffs, quotas) between countries; protectionism uses barriers to shield domestic industries. Economists generally hold that free trade raises total output.

Recession

A significant, broad-based decline in economic activity lasting more than a few months, often defined informally as two consecutive quarters of falling GDP.

Balance of trade

The difference between the value of a country's exports and its imports. A surplus means exports exceed imports; a deficit means imports exceed exports.

Gross National Product (GNP) vs. GDP

GDP counts output produced within a country's borders; GNP counts output produced by a country's residents wherever they are. They differ by net income earned abroad.

Exchange rate

The price of one currency in terms of another. A stronger (appreciating) currency makes a country's imports cheaper and its exports more expensive abroad.

The World Trade Organization (WTO)

The international body that sets the rules of global trade and provides a forum for negotiating agreements and resolving trade disputes among member states.

Percentage change formula

Percentage change $= \frac{\text{new value} - \text{old value}}{\text{old value}} \times 100$. A move from 50 to 60 is $\frac{10}{50}\times 100 = 20\%$.

Mean, median, and mode

The mean is the average (sum ÷ count); the median is the middle value when data are ordered; the mode is the most frequent value. They are the three common measures of central tendency.

How to convert a fraction to a percent

Divide the numerator by the denominator and multiply by 100. For example, $\frac{3}{4} = 0.75 = 75\%$.

Ratio

A comparison of two quantities by division, written a : b or $\frac{a}{b}$. A ratio of 3 : 1 means the first quantity is three times the second.

Range and standard deviation

The range is the difference between the largest and smallest values; standard deviation measures how spread out values are around the mean. Both describe variability.

Probability of an event

Probability $= \frac{\text{favorable outcomes}}{\text{total possible outcomes}}$, a number from 0 (impossible) to 1 (certain). The probability of rolling a 4 on a fair die is $\frac{1}{6}$.

Reading a data table or chart

Identify the variables on each axis or column, note the units and scale, then read values at the point of interest. Watch for misleading scales or truncated axes.

Percent increase vs. percentage points

A rise from 4% to 6% is a 2-percentage-point increase but a 50% relative increase $\left(\frac{2}{4}\times100\right)$. The two are not interchangeable.

Correlation

A statistical measure of how two variables move together, from −1 (perfect inverse) to +1 (perfect direct). Correlation does not by itself establish causation.

Order of operations (PEMDAS)

Evaluate in this order: Parentheses, Exponents, Multiplication and Division (left to right), then Addition and Subtraction (left to right).

Subject-verb agreement

A verb must agree in number with its subject. With indefinite pronouns like 'each,' 'every,' and 'either,' use a singular verb: 'Each of the employees has a desk' (not 'have').

Principal vs. principle

'Principal' means main/most important (or a school head or a sum of money); 'principle' is a rule or fundamental truth. 'The principal reason' uses the adjective.

Its vs. it's

'Its' is the possessive ('the dog wagged its tail'); 'it's' is the contraction of 'it is' or 'it has' ('it's raining'). The apostrophe never marks possession here.

Affect vs. effect

'Affect' is usually a verb meaning to influence ('the policy will affect trade'); 'effect' is usually a noun meaning a result ('the effect was clear').

Parallel structure

Items in a list or series should share the same grammatical form: 'comprehensive, informative, and well-organized' (all adjectives), not 'comprehensive, informative, and it was organized well.'

Using a semicolon

A semicolon joins two closely related independent clauses without a conjunction: 'The meeting was scheduled for 9 a.m.; however, it was postponed.' A comma alone would be a comma splice.

The serial (Oxford) comma

A comma before the final 'and' in a list of three or more items: 'her parents, Oprah Winfrey, and God.' It prevents ambiguity about whether the last items are separate.

Dangling / misplaced modifier

A modifier must clearly attach to the word it describes. 'Running for the gate, she hoped to catch her flight' is correct; 'Running for the gate, the flight was boarding' wrongly makes the flight run.

Who vs. whom

'Who' is the subject (who is calling?); 'whom' is the object (to whom did you speak?). Test: if you could answer with 'he,' use 'who'; if 'him,' use 'whom.'

Comma splice

Joining two independent clauses with only a comma ('It was late, we left'). Fix it with a period, a semicolon, or a comma plus a coordinating conjunction ('It was late, so we left').

Future perfect tense

Describes an action that will be completed before a point in the future: 'By the time the conference begins, the team will have finished its preparations.'

Active vs. passive voice

In active voice the subject performs the action ('The committee approved the plan'); in passive voice the subject receives it ('The plan was approved'). Clear writing usually favors the active voice.

Finding the main idea of a passage

The main idea is the central point the whole passage supports — stated in a thesis or inferred from the topic plus the author's stance. It covers the passage as a whole, not a single detail.

Determining the author's tone

Infer tone from word choice — especially evaluative adjectives and qualifiers. Tones may be neutral, critical, approving, or skeptical; distinguish the author's view from views they merely report.

Word meaning in context

When a passage uses a word you don't know, use surrounding clues — definitions, contrasts, examples — to infer its meaning, rather than relying on a single dictionary sense.

Avoiding redundancy (wordiness)

Cut words that repeat an idea already implied: 'final outcome,' 'climbed up,' and 'enough sufficient' are redundant. Concise, precise prose is the standard for English usage questions.

Premise vs. conclusion

A premise is a statement offered as evidence or support; the conclusion is the main point the premises are meant to prove. Find the conclusion first by asking what the argument is trying to convince you of.

Assumption (logical reasoning)

An unstated premise an argument needs in order to work — the gap between the stated evidence and the conclusion. Identifying assumptions is one of the abilities the FSOT Logical Reasoning section measures.

Valid inference

A conclusion that must be true given the stated information. A valid inference is fully supported by the passage and adds no outside knowledge — choose the answer the text logically locks in.

Sufficient vs. necessary condition

A sufficient condition guarantees a result (in 'If A then B,' A is enough to know B); a necessary condition is required for it (B must hold for A). Confusing the two is a classic reasoning error.

The contrapositive

From 'If A then B,' the valid 'If not B then not A' — negate both terms and flip them. It is always true when the original conditional is true.

Modus ponens

A valid argument form: 'If A then B; A is true; therefore B.' Affirming the sufficient condition lets you conclude the necessary one.

Modus tollens

A valid argument form: 'If A then B; B is false; therefore A is false.' Denying the necessary condition lets you deny the sufficient one — the contrapositive in action.

Affirming the consequent (fallacy)

The invalid move of concluding 'A' from 'If A then B' and 'B.' B can have other causes, so B being true does not prove A.

Denying the antecedent (fallacy)

The invalid move of concluding 'not B' from 'If A then B' and 'not A.' B may still hold for another reason, so 'not A' does not prove 'not B.'

Correlation vs. causation

Two things varying together (correlation) does not prove one causes the other (causation). The link may be coincidence, reverse causation, or a third factor. Treating correlation as cause is a common flaw.

Strengthening an argument

Add a fact that makes the conclusion more likely — typically by supporting the link between evidence and conclusion or ruling out an alternative explanation.

Weakening an argument

Add a fact that makes the conclusion less likely — for causal arguments, the strongest weakener is usually an alternative cause or a case where the effect occurs without the supposed cause.

Appeal to ignorance

The flaw of treating the absence of evidence against a claim as evidence for it: 'No one has proven it ineffective, so it must work.' Lack of disproof is not proof.

Circular reasoning

Assuming the conclusion as a premise — the argument 'proves' a claim by relying on that very claim. The reasoning goes in a circle and establishes nothing.

Straw man fallacy

Distorting an opponent's position into a weaker version, then attacking that weaker version instead of the real argument.

False dichotomy

Presenting only two options as if they were the only possibilities when other alternatives exist: 'Either we cut costs or we fail.'

Unrepresentative sample

Drawing a broad conclusion from a sample that is too small or biased to represent the whole group — a flaw in inductive reasoning.

'Some' and 'most' (quantifiers)

'Some' means at least one and reverses (some A are B → some B are A); 'most' means more than half and does not reverse. Two 'most' statements about one group guarantee a 'some' overlap.

Reasoning from the passage only

On FSOT Logical Reasoning items, the correct answer must follow from the stated information, not from facts you happen to know. Each item is self-contained — reason within the four corners of the passage.

Justifying a conclusion

To justify a conclusion is to supply the premise or principle that, added to the argument, makes the conclusion follow. It bridges the evidence to the claim the argument seeks to prove.

Parallel reasoning

Recognizing that two arguments share the same logical structure regardless of topic. Match the form — the conclusion type, the validity, and the pattern — and ignore the subject matter.

Five Foreign Service career tracks (cones)

Consular, Economic, Management, Political, and Public Diplomacy. Candidates choose one track when they register for the FSOT.

The Diplomatic and Consular functions

Diplomats represent and advance their country's interests abroad and report on conditions; consular officers protect citizens overseas and adjudicate visas and passports.

Soft power

A concept developed by Joseph Nye: a country's ability to influence others through attraction — its culture, values, and policies — rather than through coercion or payment.

Pacta sunt servanda

A Latin principle of international law meaning 'agreements must be kept' — states are obligated to carry out their treaty commitments in good faith.

State sovereignty

The principle that each state has supreme authority within its own territory and is free from outside interference — a cornerstone of the modern international system since Westphalia.

Diplomatic immunity

Under the Vienna Convention on Diplomatic Relations (1961), accredited diplomats are protected from arrest and prosecution in the host country so they can perform their duties without coercion.

Bicameral legislature

A lawmaking body with two chambers. The U.S. Congress is bicameral: the House of Representatives (by population) and the Senate (two per state).

Veto and override

The President can veto (reject) a bill passed by Congress; Congress can override the veto and make the bill law with a two-thirds vote in each chamber.

Judicial review

The power of courts to determine whether a law or government action conforms to the Constitution and to strike down those that do not. It was established in Marbury v. Madison (1803).

World War I (1914–1918)

A global conflict triggered by alliances and the assassination of Archduke Franz Ferdinand. The U.S. entered in 1917; the war ended with the Treaty of Versailles in 1919.

World War II (1939–1945)

A global conflict between the Allied and Axis powers. The U.S. entered after Pearl Harbor (1941); it ended in 1945 and reshaped the global order, leading to the Cold War and the United Nations.

The Berlin Wall

Built in 1961 to divide Soviet-controlled East Berlin from West Berlin, it became the symbol of the Cold War's 'Iron Curtain' and fell in 1989 as communism collapsed in Eastern Europe.

Globalization

The increasing interconnection of economies, cultures, and populations through trade, technology, and the movement of people and ideas across borders.

Quota (trade)

A government limit on the quantity of a good that may be imported. Like a tariff, it protects domestic producers but raises prices and reduces the supply available to consumers.

Budget deficit vs. national debt

A deficit is the shortfall when a government spends more than it collects in a single year; the national debt is the cumulative total of past deficits the government still owes.

Unemployment rate

The percentage of the labor force that is jobless and actively seeking work. It excludes people who are not looking for work, so it does not capture all who lack jobs.

Mean vs. median in skewed data

When data are skewed by outliers (such as a few very high incomes), the median often represents the 'typical' value better than the mean, which the extreme values pull upward.

Reading an FSOT logic stimulus

Separate the premises (support) from the conclusion (main point), identify any conditional statements, and note the gap the argument assumes — then answer exactly what the question asks.

Identifying a logical flaw

Name the error in how the argument reasons from evidence to conclusion — e.g., mistaking correlation for cause, treating a necessary condition as sufficient, or generalizing from a biased sample.

The QEP (Qualifications Evaluation Panel)

After the FSOT, a panel reviews each candidate using a total-candidate approach — weighing the FSOT score together with education, work background, and personal-narrative responses to decide who advances.

How FSOT candidates are selected to advance

The revamped FSOT has no fixed passing score. The Department invites candidates to the next step based on the highest scores and the needs of the Foreign Service — a competitive ranking, not a pass/fail cutoff.
