After working hard and earning honors during his first year in a difficult engineering program, andrew was awarded the best student in his group. while handing him the certificate, his professor said, "well done," without any enthusiasm, and andrew also noticed the professor didn’t meet his eye. from the professor’s reaction, andrew knew he was not happy with him for some reason. which dimension of communication message is implied by the professor

The correct answer is Relational dimension.

Explanation:

In communication there are two dimensions the actual content of a communication which is the content or the information being explicitly discussed and the other dimension which is the relational dimension which is the part of the communication that is not explicit in it but it's whatever the message communicate about the messenger's feelings towards the other person or the listener. Therefore in Andrew's interaction with the professor we can clearly evidence that the message that the professor gave corresponds to the Relational dimension.

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.
