What is a failed state? Offer three examples of failed states with an explanation on each one?

The correct answer is B. Many of the settlers of Missouri were slaveowners from the South.

Explanation:

Missouri's first settlers were slaveholders that had large plantations in the area.

Missouri, initially part of the Purchase of Louisiana, was admitted as a slave state on August 10, 1821 as part of the Missouri Compromise.

In the early years of the nineteenth century, although a slave state, Missouri was not a fiery defender of slavery, so the controversy on this issue was very broad. When Abraham Lincoln won the presidential election, the state government convened a convention to reconsider its relationship with the Union; In the voting, the secessionist delegates were defeated and it was declared that there was no cause to break with the Union.

Therefore, during the Civil War, Missouri was divided: some parts adhered to the Union while others joined the Confederate states.
