After Lana got a low grade on her first French exam, she told her roommate that she was dropping the course because she wasn't good at foreign languages and would never be able to figure out French grammar. Lana is best classified as having a pessimistic explanatory style because: A. she tends to blame others for failures and setbacks in her life and takes personal credit for positive outcomes. B. she uses internal, stable, and global explanations for negative events. C. she uses external, unstable, and specific explanations for negative events. D. she has a behavioral and emotional style characterized by a sense of time urgency, hostility, and competitiveness.

she uses internal, stable, and global explanations for negative events.

Explanation:

intemality (It's me) , stability (It's going to last  forever)  and globality (It's going to  undermine everything I do) does are the characteristics perculier to Pessimistic explanatory style.

Pessimists personally blame themselves for bad occurence and consider  the root cause to be a fixed factor and believe that such events will continue indefinitely.Also, individuals with pessimistic explanatory styles are more likely to experience extensive and chronic signs of helplessness when faced with uncontrollable negative events. In the case of Lana, because she failed french one time, she believes she is never good at foreign language (internality: its me) and would never be able to understand it (stability: it would last forever) which resulted in her concluding that she will drop the course (globality: its going to undermine everything she does).

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.
