Answers

The plantation system became dependent upon slave labor during the 1700s because agriculture became more popular in the Southern colonies and they ended up heavily relying on plantations for their source of income.

During this time, the South was primarily getting their income from plantations and growing cash crops. Cash crops were crops that sold for a lot, mostly overseas. Southern colonists would focus on selling cash crops and trying to expand their plantations, which caused them to need a lot of slave labor. First, they focused on mostly indentured servants, people who were trying to repay their masters for buying their passage to the colonies, but when that deemed to be too much work, many Southerners turned to slaves for their labor.

The North was not focused on agriculture like the South was, they were focused on industrialization. They did not need slave labor in order to maintain their income, so they did not have to worry about if what they were doing was morally wrong or not.

Answers

Answer:

englightened is = having a deep spiritual understanding.

nirvana is = a state of perfect happiness in which there is no suffering.

Upanishads is = a collection of texts that form the basis of the Hindu religion

the eight fold path is = a way to end suffering, also called the middle way.

karma is = the belief that every action causes a reaction in the universe

The following are correctly matched with its description.

enlightened is = having a deep spiritual understanding. The idea of spiritual enlightenment has come to be associated with self-realization, the true self, and the false self in western culture, where it is thought to be a significant essence that is obscured by social conditioning.

nirvana is = a state of perfect happiness in which there is no suffering. Nirvana is an idealized state of bliss and contentment similar to heaven. Nirvana is the highest state that a person can achieve in both Hinduism and Buddhism. It is a state of enlightenment in which a person's personal desires and suffering vanish.

Upanishads are = a collection of texts that form the basis of the Hindu religion. The Upanishads depict a world that is interconnected and has a single, overarching principle that underlies the apparent diversity of the universe. This principle is known as brahman and can be expressed in any way.

the eightfold path is = a way to end suffering, also called the middle way. The term "middle way" describes the Buddhist understanding of practical life, which steers clear of the extremes of self-denial and self-indulgence, as well as the perspective on reality, which steers clear of the extremes of eternalism and annihilationism.

karma is = the belief that every action causes a reaction in the universe. The idea of karma states that you will receive back from the universe whatever you put out into it, good or bad.

What did the Buddha say about karma?

According to what the Buddha taught, beings are tethered to the cycle of rebirth because of their past actions. The only way to be free from karma is to give up on the idea that one has a real, permanent self.

Thus, the mentioned above are correctly matched with its description.

Answers

Answer:

Two commitments that could have been used to prevent or delay civil war were the Clay commitment and the Missouri commitment.

Explanation:

The Clay compromise (1850) and the Missouri compromise (1820) attempted to lessen tension between the southern and northern states and to establish guidelines on slave labor in the country and the expansion of slavery. The intention of these two commitments was to make agreements that would benefit both states within their particularities, delaying tensions between them that would create separatist movements that would provoke a war that tried to separate the country, as was the war of secession.

Both agreements dealt with the slavery issue, but did not prohibit it throughout the national territory, nor did it even create an improvement in life and treatment for the black population, because, as it is worth mentioning, not even the southern states had the will to free the slaves and preferred leave southern states with the right to enslave, if that would prevent a major conflict.

Why were Native Americans willing to temporarily be the military allies of European powers in North America?

The Native Americans were willing to temporarily be the military allies of European powers in North America as they are usually promised autonomy and "freedom". On top of that, it can also be a guarantee to being able to continue to stay on their native lands. A relationship with the Europeans would also open up access to European goods and weapons, which was proven superior against the traditional bow and arrows.
