The properly marked source document states: (c) the training exercise will last three days. (s) the training exercise will begin 21 april. the security classification guide (scg) states: the length of the training exercise is confidential. the dates of the training exercise are secret. the new document states: ( ) the training exercise lasts three days, ending on 24 april. what is the classification of the statement in the new document?

Secret.

Explanation:

Derivative classification involves the incorporation of new information which has previously been classified and the labeling of the new document as per its classification. It identifies the authorized sources while classifying with the concepts 'revealed by' and 'contained in'.

As per the question, the statement in the new document could be classified as secret as it exemplifies confidential information relating to the length of the training exercise. Thus, it could be classified as 'secret'.

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.
