Achild who lives in a stressful home environment is fearful when interacting with other children in kindergarten, despite the teacher's efforts to encourage her. she is increasingly ignored by her peers and as a result does not develop skills in initiating play. her family moves, she starts first grade at a new school, and she is ignored by peers and picked on by a bully, who is easily able to make her fearful and upset. the best term to describe this developmental pattern is

a developmental cascade        

Explanation:

Developmental cascade: It refers to the increasing consequences for many interactions and transaction development that occurs in a developing system and results in a lay-out effect across different levels, among the realm at the same level, and across various generations and systems.

The transactions and interactions that occur in developmental cascade exist within and between macroscopic i.e cultural and microscopic i.e biological factors constituting the system.

According to the question, the child is being affected by both microscopic and macroscopic factors.

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.
