(A) Freeing all enslaved people living in the western territories
(B) Immediately ending the importation of enslaved people from Africa
(C) Admitting Missouri as a slave state and Maine as a free state, and banning slavery north of the 36 degrees 30 minutes line in the rest of the Louisiana Territory ✓
(D) Letting the settlers of each new territory decide the slavery question by popular vote

By pairing Missouri and Maine, the compromise kept the Senate evenly divided between free and slave states, and it drew a geographic line north of which slavery was banned in the remaining Louisiana Purchase lands.

Question 19 · 2 pts

In the Dred Scott v. Sandford decision of 1857, the Supreme Court ruled that

(A) an enslaved person who entered a free state was automatically made free
(B) racial segregation of public facilities was legal as long as the facilities were equal
(C) enslaved people were property, were not citizens, and Congress could not prohibit slavery in the territories ✓

(A) The 15th Amendment
(B) The 13th Amendment
(C) The 14th Amendment ✓
(D) The 10th Amendment

Ratified in 1868, the 14th Amendment made all persons born or naturalized in the United States citizens and required states to provide equal protection of the laws, overturning the Dred Scott ruling on citizenship.

Question 23 · 2 pts

Which development was a major cause of the rising sectional tension between the North and South during the 1850s?

(A) A debate over quotas limiting immigration from southern and eastern Europe
(B) A conflict over granting women the right to vote nationwide
(C) A dispute over whether the United States should join the League of Nations
(D) Disagreement over whether slavery should be allowed to expand into the western territories ✓

Events like the Kansas-Nebraska Act and the Dred Scott decision deepened the divide over the spread of slavery into new territories, which was the defining sectional issue of the 1850s.

Question 26 · 2 pts

The Missouri Compromise of 1820 attempted to ease sectional tensions over slavery by taking which action?

(A) Immediately abolishing slavery everywhere in the Louisiana Territory
(B) Allowing the settlers of each new territory to decide the slavery question by popular vote
(C) Admitting Missouri as a slave state and Maine as a free state, and banning slavery in the northern part of the Louisiana Territory ✓

(B) It declared enslaved people free in the Confederate states still in rebellion, but did not apply to the loyal border states ✓
(C) It granted formerly enslaved people the right to vote

(A) The amendment that granted citizenship and guaranteed equal protection of the laws

(C) A guarantee that the right to vote could not be denied on account of race, color, or previous condition of servitude ✓

Question 3 · 2 pts

The Missouri Compromise of 1820 admitted Missouri as a slave state and Maine as a free state, and banned slavery in the rest of the Louisiana Purchase territory north of the 36°30' line. The primary purpose of this compromise was to

(A) allow each new territory to vote on slavery through popular sovereignty
(B) abolish slavery immediately throughout all United States territories
(C) maintain the balance between free and slave states in the United States Senate ✓
(D) give Congress the power to regulate slavery only within existing state borders

Worked solution

$Before 1820 there were 11 free states and 11 slave states, keeping Senate power balanced.$

$Missouri's admission as a slave state alone would have upset that balance.$

$Pairing Missouri with Maine, and drawing the 36°30' line, preserved the sectional balance in the Senate.$

Answer: maintain the balance between free and slave states in the United States Senate

The Missouri Compromise was designed to preserve the equal number of free and slave states so that neither North nor South could dominate the Senate, temporarily easing sectional tensions over slavery's expansion.

Question 10 · 2 pts

The 14th Amendment (1868) states, in part, "No State shall... deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws." This amendment was primarily adopted during Reconstruction in order to

(A) abolish slavery throughout the United States
(B) guarantee citizenship and legal protections to formerly enslaved African Americans ✓
(C) give the President the power to appoint state governors in the former Confederacy
(D) grant women the right to vote in federal elections

Worked solution

$The 13th Amendment (1865) had already abolished slavery, but freedpeople's citizenship status and rights remained uncertain.$

$Southern states passed Black Codes restricting the rights of freedpeople after the Civil War.$

$The 14th Amendment guaranteed citizenship to all persons born in the United States and required equal protection and due process under state law.$

Answer: guarantee citizenship and legal protections to formerly enslaved African Americans

The 14th Amendment was adopted to secure citizenship and constitutional protections for newly freed African Americans against discriminatory state laws passed after the Civil War, such as the Black Codes.

Question 17 · 2 pts

During the 1840s, many Americans supported the idea of Manifest Destiny, the belief that the United States was destined to expand across the North American continent. This belief was primarily used to justify

(A) the annexation of Texas and the acquisition of Oregon and California territories ✓
(B) the establishment of the Monroe Doctrine in 1823
(C) the construction of the transcontinental railroad after the Civil War
(D) the purchase of Alaska from Russia

Worked solution

$Manifest Destiny held that American expansion was inevitable and justified by providence and progress.$ define the idea

$This belief fueled support for annexing Texas (1845), settling the Oregon boundary dispute, and acquiring California and the Southwest through the Mexican-American War (1846-1848).$

$The Alaska purchase (1867) and the Monroe Doctrine (1823) occurred in different contexts and time periods.$

Answer: the annexation of Texas and the acquisition of Oregon and California territories

Manifest Destiny was the ideology used in the 1840s to justify westward expansion, most directly the annexation of Texas and the acquisition of Oregon and Mexican Cession territory, since Americans believed expansion across the continent was both justified and inevitable.

Question 27 · 4 pts · constructed response

Read the summary below of the Supreme Court's decision in Dred Scott v. Sandford (1857), then answer the question that follows. In its ruling, the Supreme Court held that enslaved people and their descendants were not and could never become United States citizens, and therefore had no standing to sue in federal court. The Court also ruled that Congress had no constitutional authority to ban slavery in the territories, declaring the Missouri Compromise's restriction on slavery unconstitutional. Explain one way this decision intensified sectional conflict over slavery in the years leading up to the Civil War.

Model answer: By ruling that Congress could not prohibit slavery in the territories, the decision struck down the Missouri Compromise line and removed any judicial limit on slavery's expansion, alarming Northerners who feared slavery would spread nationwide. This convinced many antislavery Northerners that compromise was impossible and strengthened the new Republican Party, which had formed to oppose the extension of slavery, while it emboldened Southern slaveholders, deepening the sectional divide that led toward secession and war.

Worked solution

$Identify the ruling's two key holdings: no citizenship for Black Americans, and no congressional power to ban slavery in territories.$

$Recognize this invalidated the Missouri Compromise's restriction on slavery north of 36°30'.$

$Explain the Northern reaction: fear that slavery could spread into all territories, growing support for the Republican Party.$

$Explain the Southern reaction: emboldened defense of slavery's expansion.$

$Conclude that the ruling removed a political compromise and deepened distrust between North and South.$

Answer: By ruling that Congress could not prohibit slavery in the territories, the decision struck down the Missouri Compromise line and removed any judicial limit on slavery's expansion, alarming Northerners who feared slavery would spread nationwide. This convinced many antislavery Northerners that compromise was impossible and strengthened the new Republican Party, which had formed to oppose the extension of slavery, while it emboldened Southern slaveholders, deepening the sectional divide that led toward secession and war.

Dred Scott v. Sandford eliminated the compromise framework that had limited slavery's spread since 1820, convincing many Northerners that the political system could no longer contain the slave power and strengthening the Republican Party's antislavery coalition, while Southern leaders saw the ruling as vindication. This mutual hardening of positions is a direct cause historians cite for the escalating sectional crisis of the late 1850s.

Question 4 · 2 pts

The Missouri Compromise of 1820 attempted to address sectional conflict over slavery by

(A) admitting Missouri as a slave state and Maine as a free state while banning slavery north of the 36°30' line in the remaining Louisiana Territory ✓
(B) allowing popular sovereignty to decide the slavery question in every new territory
(C) immediately abolishing slavery in all territories acquired from the Louisiana Purchase
(D) admitting Missouri and Maine both as slave states to preserve the balance in Congress

Worked solution

$Missouri's request for admission as a slave state threatened the balance of free and slave states in the Senate.$

$Congress paired Missouri's admission with Maine's admission as a free state to maintain balance.$

$A geographic line, 36°30' latitude, was drawn to determine future slave and free territory in the Louisiana Purchase lands.$

Answer: admitting Missouri as a slave state and Maine as a free state while banning slavery north of the 36°30' line in the remaining Louisiana Territory

The Missouri Compromise preserved the North-South balance of power in the Senate by admitting Missouri as a slave state and Maine as a free state, and it drew the 36°30' line to regulate slavery's expansion into remaining western territories.

Question 5 · 2 pts

President Abraham Lincoln issued the Emancipation Proclamation in January 1863 primarily to

(A) end the Civil War by offering the Confederacy a peace settlement
(B) immediately end slavery throughout the entire United States, including the loyal border states
(C) declare that enslaved people in Confederate-held territory were free, weakening the South's war effort and adding a moral purpose to the Union cause ✓
(D) grant full citizenship and voting rights to all formerly enslaved African Americans

Worked solution

$The Proclamation applied only to areas still in rebellion against the Union, not to loyal border states.$

$It reframed the Civil War as a fight to end slavery, discouraging European support for the Confederacy.$

$It also permitted the enlistment of Black soldiers into the Union army.$

Answer: declare that enslaved people in Confederate-held territory were free, weakening the South's war effort and adding a moral purpose to the Union cause

The Emancipation Proclamation freed enslaved people only in Confederate territory, using presidential war powers to undermine the South's labor force while giving the Union cause a stronger moral dimension; full abolition required the 13th Amendment.

Question 14 · 2 pts

In 1820, Congress resolved a dispute over the balance of free and slave states by admitting Missouri as a slave state and Maine as a free state, while banning slavery in the rest of the Louisiana Territory north of the 36 degrees 30 minutes latitude line. This agreement is known as the

(A) Missouri Compromise ✓
(B) Kansas-Nebraska Act
(C) Compromise of 1850
(D) Wilmot Proviso

Worked solution

$The stem describes the 1820 admission of Missouri and Maine and the 36 degrees 30 minutes line.$

$This specific pairing of states and the latitude line uniquely identifies the Missouri Compromise.$

$The Compromise of 1850 and Kansas-Nebraska Act (1854) addressed later disputes and are chronologically later.$

Answer: Missouri Compromise

The Missouri Compromise of 1820 temporarily eased sectional tension by maintaining an equal number of free and slave states and establishing a geographic line for future territories.

Question 27 · 4 pts · constructed response

In 1820, Congress passed a law admitting Missouri as a slave state and Maine as a free state at the same time, and it prohibited slavery in the remaining Louisiana Purchase territory north of the 36°30' latitude line. Identify this law, explain its immediate purpose, and describe why it only temporarily eased sectional tension over slavery.

Model answer: This was the Missouri Compromise of 1820. Its immediate purpose was to preserve the balance between free and slave states in the Senate by admitting Maine and Missouri together and to settle the future status of slavery in the rest of the Louisiana Purchase territory by drawing the 36°30' line. It only temporarily eased tensions because it did not resolve the underlying disagreement over whether slavery should expand into new territories, and as the nation continued to acquire land, most notably after the Mexican-American War, the same conflict over slavery's expansion resurfaced and deepened sectional division.

Worked solution

$Identify the law described: the Missouri Compromise of 1820.$

$State its immediate purpose: keep an equal number of free and slave states (via Maine/Missouri) and set a geographic line (36°30') for slavery's future expansion.$

$Explain why the underlying dispute remained: new territorial acquisitions kept reopening the question of whether slavery would spread.$

$Conclude that the compromise was a temporary fix that delayed rather than resolved sectional conflict, foreshadowing later crises.$

Answer: This was the Missouri Compromise of 1820. Its immediate purpose was to preserve the balance between free and slave states in the Senate by admitting Maine and Missouri together and to settle the future status of slavery in the rest of the Louisiana Purchase territory by drawing the 36°30' line. It only temporarily eased tensions because it did not resolve the underlying disagreement over whether slavery should expand into new territories, and as the nation continued to acquire land, most notably after the Mexican-American War, the same conflict over slavery's expansion resurfaced and deepened sectional division.

The Missouri Compromise maintained a fragile sectional balance in Congress and drew a line limiting slavery's expansion, but because it left the core dispute over slavery unresolved, later territorial growth reignited the conflict, contributing to the sectional crisis that led toward the Civil War.

Question 3 · 2 pts

"Missouri shall be admitted to the Union as a slave state, Maine shall be admitted as a free state, and slavery shall be prohibited in the remaining Louisiana Territory north of the 36°30' line." This 1820 agreement is known as the

(A) Missouri Compromise ✓
(B) Compromise of 1850
(C) Wilmot Proviso
(D) Kansas-Nebraska Act

Worked solution

$The date (1820) and the paired admission of Missouri and Maine identify the Missouri Compromise.$

$The 36°30' line was the specific geographic boundary set by this compromise for future slave/free territory.$

$The Compromise of 1850 and Kansas-Nebraska Act (1854) came later and used different mechanisms (popular sovereignty).$

Answer: Missouri Compromise

The Missouri Compromise of 1820 temporarily preserved the balance of slave and free states in Congress by admitting Maine and Missouri together and drawing the 36°30' line through the Louisiana Territory.
