Answer:    Functional magnetic resonance imaging (fMRI)

Explanation:  Whether in the right or left hemisphere, increased brain activity associated with increased blood flow is measured by functional magnetic resonance imaging (fMRI) or functional MRI. This technique is based on the fact that the activation of neurons in the brain is related to blood flow also in the brain. When the brain is strained by some perceptual task, that is, the part of the brain responsible for some perceptual function, then the blood flow through that part of the brain increases. This again means a change in the magnetic image being recorded, due to the fact that the blood carries certain charges and with their increase that can be recorded, and due to the activity of the part of the brain, the increased activity of neurons can be measured.

Mrac [35]

Answer:

because an educated slave would be more difficult to control.

Explanation:

The main reason why plantation owners did not want to educate their slaves was because they believed that an educated slave would be more difficult to control. If a slave was educated, he would be able to read. Reading usually exposes people to new ideas. It leads them to question rules, society, other people and themselves. An educated slave would most likely become more unhappy with his situation and would believe that change was necessary. This could lead him to become more rebellious.

<span>Originalism. Originalism is the philosophy/perspective that the Constitution is stable in its meaning and interpretation and should not diverge from what the framers of the Constitution laid out in its creation. Most originalists adhere to the "original meaning" doctrine, which advocates that the Constitution must be interpreted in the cultural and political contexts that were present when the document was created; that is to say that modern moral and philosophical leanings should not factor into how issues are addressed by the Constitution as it stands.</span>
