Acriterion for waiving informed consent is that, when appropriate, subjects are provided additional pertinent information after the study. in which of the following studies would it not be appropriate to provide subjects with information about missing elements of consent: a study involving decision-making games in which subjects were led to believe that they were interacting with another student in another room, but were actually interacting with a computer programmed to provide consistent responses to all subjects. a study in which researchers told students that they would be given a quiz after reading some study materials when the researchers did not intend to use a quiz, but were attempting to focus subjects' attention on the material. a study in which subjects were told that they performed in the third quartile on an anagram task when in reality students were randomly assigned scores that were not related to their actual performance. a study in which subjects were assigned to study activities based on an undesirable or unflattering physical characteristic as assessed by members of the research team.

A study in which subjects were assigned to study activities based on an undesirable or unflattering physical characteristic as assessed by members of the research team.

Explanation:

In the other studies, subjects don't need to know further information about the research and in some of them, their knowledge about it could hinder the research methods or results. Missing elements of consent wouldn't harm any of the research subjects.

It wouldn't be appropriate to miss elements of consent in a study where subjects were assessed by members of the research team.

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.
