A free negro of the African race, whose ancestors were brought to this country and sold as slaves, is not a "citizen” within the meaning of the Constitution of the United States. When the Constitution was adopted, they were not regarded in any of the States as members of the community which constituted the State, and were not numbered among its "people or citizens.” Consequently, the special rights and immunities guarantied to citizens do not apply to them. And not being "citizens” within the meaning of the Constitution, they are not entitled to sue in that character in a court of the United States, and the Circuit Court has not jurisdiction in such a suit.

–Dred Scott v. Sandford,
Supreme Court of the United States

Which details does Taney use as evidence to support his reasoning? Check all that apply.

“A free negro of the African race”
“whose ancestors were brought to this country and sold as slaves”
“not a ‘citizen’ within the meaning of the Constitution of the United States”
“they were not regarded in any of the States as members of the community”
“not numbered among its ‘people or citizens’”

Select the correct answer.
Read this excerpt from Thomas Paine's essay "Common Sense":

Mankind being originally equals in the order of creation, the equality could only be destroyed by some subsequent circumstance; the distinctions of rich, and poor, may in a great measure be accounted for, and that without having recourse to the harsh, ill-sounding names of oppression and avarice. Oppression is often the CONSEQUENCE, but seldom or never the MEANS of riches; and though avarice will preserve a man from being necessitously poor, it generally makes him too timorous to be wealthy.

But there is another and greater distinction, for which no truly natural or religious reason can be assigned, and that is, the distinction of men into KINGS and SUBJECTS. Male and female are the distinctions of nature, good and bad the distinctions of heaven; but how a race of men came into the world so exalted above the rest, and distinguished like some new species, is worth inquiring into, and whether they are the means of happiness or of misery to mankind.

What is Thomas Paine's central claim in this excerpt?

A.
There will always be a distinction between kings and their subjects.
B.
The equality that humans enjoyed during creation has been ruined because of war and famine.
C.
Not all people who belonged to the upper sections of society were cruel.
D.
The differences between the kings and the subjects were not religious or natural.
