- the money earned at work
- the study session given up Correct answer.
- the cost of the commute

- Egypt
- Sumer Correct answer.
- the Indus Valley
- the Huang He valley
Explanation
Sumerian city-states such as Ur and Uruk developed in southern Mesopotamia by about 3500 BCE and produced early writing, law, and urban government. The other options name civilizations that developed in different river systems.

- the Virginia Plan
- the Federalist Papers
- the Articles of Confederation
- the Bill of Rights Correct answer.
Explanation
Ratified in 1791, the first ten amendments are called the Bill of Rights and protect liberties such as speech, religion, and due process. The other terms refer to documents or proposals from the founding era that served different purposes.
Question 7Social Studies Content

- the Brazos River
- the Sabine River
- the Rio Grande Correct answer.
- the Red River

The Rio Grande separates Texas from Mexico from the El Paso area to the Gulf of Mexico. Texas's other major border rivers separate it from neighboring U.S. states.
Question 8Social Studies Content
In a market economy, if demand for a product rises while supply stays the same, the price of the product generally
- is set by the government
- falls
- stays the same
- rises Correct answer.
Explanation
When demand increases and supply is unchanged, buyers compete for a limited quantity of goods, pushing the equilibrium price upward. Prices adjust rather than remaining fixed in a market system.
Question 9Social Studies Content
The Thirteenth Amendment to the U.S. Constitution
- gave Black men the vote
- guaranteed due process
- abolished slavery Correct answer.
- banned poll taxes
Explanation
Ratified in 1865, the Thirteenth Amendment abolished slavery and involuntary servitude except as punishment for a crime. The other protections came from later amendments in the Reconstruction and civil rights eras.

Question 11Social Studies Content
The Magna Carta of 1215 is important to the development of democratic government because it
- limited the king's power under law Correct answer.
- abolished the feudal system
- created the first written constitution

Explanation
English nobles forced King John to accept that the monarch was bound by law and owed certain protections to free men, a principle later invoked to support limited government and due process. The charter did not restructure English society or government wholesale.
Question 12Social Studies Content
After the Civil War, Texas ranchers drove cattle north primarily to
- reach railroad shipping points in Kansas Correct answer.
- find better grazing land in the northern plains
- escape the high taxes charged by state officials
- avoid raids by American Indian groups
Explanation
Railheads such as Abilene connected Texas longhorn herds to eastern beef markets, making the long drives profitable in the 1870s and 1880s. Hazards along the trail, such as raids, were risks rather than reasons for the drives.
Question 13Social Studies Content

- the president serves as commander in chief
- the courts may review laws passed by Congress
- power is divided between national and state governments Correct answer.
- each branch of government can check the other two branches
Explanation
Federalism divides governing authority between a national government and state governments, each with its own powers and responsibilities. The other options describe checks and balances, judicial review, and civilian control of the military.

The Soviets agreed in October 1962 to withdraw their missiles in exchange for a U.S. pledge not to invade Cuba and the quiet removal of U.S. missiles from Turkey. The standoff ended through negotiation rather than invasion.
Question 15Social Studies Content
The Industrial Revolution began in Great Britain in the 1700s largely because Britain had
- a large peasant population loyal to the crown
- a powerful navy that controlled the Atlantic
- coal, iron ore, and capital for investment Correct answer.
- great mineral wealth in its African colonies
Explanation
Britain possessed abundant coal and iron deposits, accumulated capital from commerce, and colonies that supplied raw materials and markets, which together allowed factory production to take off. The other factors were not the foundation of early industrialization.
Question 16Social Studies Content
Which of the following is an example of a push factor in migration?
- better schools at the destination
- abundant jobs at the destination
- political freedom at the destination
- famine in the home country Correct answer.
Explanation
Push factors are conditions that drive people away from a place, such as famine, war, or persecution, while pull factors attract them toward a new location. Famine in the home country is a classic push factor.
Question 17Social Studies Content
A distinctive feature of the current Texas Constitution, adopted in 1876, is that it
- limits the governor to a single term in office
- gives the governor strong cabinet powers
- provides for a parliamentary form of government
- has been amended more than 500 times Correct answer.
Explanation
Because the 1876 constitution is long and highly detailed and sharply limits state government, it has required hundreds of amendments since adoption. Texas retains a presidential-style system in which many executive officials are elected independently.

- the military draft of young men
- wartime rationing of food and gasoline
- Japanese American internment Correct answer.
- government sales of war bonds
Explanation
Executive Order 9066 led to the forced removal and confinement of about 120,000 Japanese Americans, most of them citizens; Congress later apologized and authorized reparations. The other measures applied broadly and were upheld as legitimate wartime policies.
Question 21Social Studies Content
The Supreme Court's decision in McCulloch v. Maryland (1819) established which principle?
- states may tax the agencies of the federal government
- the Supreme Court has original jurisdiction in all cases
- Congress may not charter a national bank
- federal law is supreme over conflicting state law Correct answer.
Explanation
Chief Justice Marshall held that Congress had the implied power to charter the Second Bank and that Maryland could not tax it, because the federal government is supreme within its sphere. The ruling relied on the necessary and proper clause and the supremacy clause.
Question 22Social Studies Content

European powers at Berlin agreed on procedures for claiming African territory, such as effective occupation, which accelerated the scramble for colonies. No African representatives took part in the negotiations.
Question 23Social Studies Content
Between 1910 and 1970, millions of African Americans left the rural South for northern cities. Which combination best explains this movement?
- industrial jobs in northern cities and continued racial violence in the South Correct answer.
- free land offered by the federal government and the promise of political office
- a federal relocation program and the growth of suburban housing
- the end of sharecropping alone and the collapse of southern agriculture
Explanation
The Great Migration is explained by the pull of industrial employment in northern cities together with the push of segregation, disenfranchisement, and racial violence in the South. Single-cause explanations miss either the direction or the scale of the movement.
Question 24Social Studies Content
During a severe recession, an economist following Keynesian theory would most likely recommend
- increasing government spending to stimulate demand Correct answer.
- waiting for wages and prices to fall without government action
- reducing the money supply to bring down inflation
- raising taxes and cutting spending to balance the budget
Explanation
Keynesians hold that during a downturn government should spend more or cut taxes to raise aggregate demand and reduce unemployment. Balanced-budget and monetary-contraction approaches reflect different schools of thought.

The annexation of Texas by the United States in 1845 contributed most directly to
- the completion of a transcontinental railroad
- the purchase of Alaska from Russia
- the outbreak of the Civil War
- war with Mexico and a dispute over the Texas border Correct answer.

- the reserved powers of the states
- a legislative override of a veto Correct answer.
- judicial review of a statute
- the formal amendment process
Explanation
The Constitution allows Congress to enact a bill over a presidential veto by a two-thirds vote in each house, one of several checks the branches exercise over one another.

- the Alamo
- Goliad
- San Jacinto Correct answer.
- Coleto Creek
Explanation
On April 21, 1836, Sam Houston's army defeated Santa Anna's forces at San Jacinto, and the captured Mexican president later recognized Texas independence.
Question 30Social Studies Content
A student writes a report using a diary kept by a soldier in 1863 and a chapter from a 2015 textbook about the Civil War. Which statement best classifies these sources?
- Both sources are primary sources.
- The diary is a primary source, and the textbook chapter is a secondary source. Correct answer.
- Both sources are secondary sources.
- The diary is a secondary source, and the textbook chapter is a primary source.
Explanation
A primary source is a firsthand record made by a participant or witness, while a secondary source interprets and analyzes such records after the fact. The soldier's diary is firsthand, and the later textbook chapter is an interpretation.

- the grade earned on the essay
- the cost of the essay's materials
- the two hours spent writing
- the math study time given up Correct answer.
Explanation
Opportunity cost is the value of the next best alternative that is forgone when a choice is made. Finishing the essay means giving up the math study time that could have been used instead.
Question 33Social Studies Content
A population pyramid has a very broad base and a narrow top. This shape most strongly suggests a population with
- a declining total population
- a large migrant population
- high birth rates and low life expectancy Correct answer.
- a high proportion of elderly residents and low birth rates
Explanation
A broad base reflects a large share of children, which indicates high birth rates, while the narrow top reflects relatively few elderly people, a pattern typical of lower life expectancy.

- the discovery of the Americas by Columbus
- start of the Crusades
- the decline of the Silk Roads

Question 46Social Studies Content
Country A can produce a unit of cloth in 2 hours or a unit of wine in 4 hours. Country B can produce a unit of cloth in 3 hours or a unit of wine in 12 hours. According to the principle of comparative advantage, Country A should
- specialize in cloth production and trade for wine
- produce only cloth because it takes less time than Country B
- specialize in wine production and trade for cloth Correct answer.
- produce both goods because it uses less time for each
Explanation
Comparative advantage compares opportunity costs, not hours alone. Country A gives up 2 cloth to make a unit of wine while Country B gives up 4 cloth, so A should specialize in wine and B in cloth.
Question 47Social Studies Content
Moist air rises over a mountain range, cools, and drops heavy rain on the windward slope; on the leeward side, sinking air warms and stays dry. Which process best explains this pattern?
- the Coriolis effect deflecting wind
- warm ocean currents along the coast
- adiabatic cooling and warming of air Correct answer.
- convection from urban heat islands
Explanation
Rising air expands and cools adiabatically, so it releases moisture as precipitation, while descending air on the far side compresses and warms, raising its moisture capacity and producing a rain shadow.
Question 48Social Studies Content
