After suffering trauma to his brain, Jack experienced profound alterations in his personality. Prior to his accident he was a prudent, responsible employee. Afterward, he was childlike in mental capacity, impulsive, and unable to control his emotions. Jack's injuries were most likely located in which area of the brain

Prefrontal cortex.

Explanation:

The prefrontal cortex is an integral part of an individual's cognitive control functioning. It covers the front part of the frontal lobe, where various sensory modalities are integrated.

So, when Jack suffers the trauma to his brain, the alterations to his personality are the effects of the damage in his prefrontal cortex. Since this part of the brain is responsible for one's executive movements like focus, understanding the consequences of one's actions, personality development, decision making, etc, Jack's trauma left him devoid of these abilities.

Thus, his injury is in his brain's prefrontal cortex.

step-by-step explanation:

trade regulation is a field of law, often bracketed with antitrust (as in the phrase “antitrust and trade regulation law”), including government regulation of unfair methods of competition and unfair or deceptive business acts or practices. antitrust law is often considered a subset of trade regulation law. franchise and distribution law, consumer protection law, and advertising law are sometimes considered parts of trade regulation law.

in general the theory of economics says that the more open to trade a country is the better   the result for the same country and the whole economies.

in real life countries impose taxes, quotas, etc which is not so good for the economies.

this kind of commercial war between the usa and china is slowing down the growth of the whole world so we can say that it is a draw back of trade regulations. and the free trade agreements are benefits of trade regulations.
