a) the principle of checks and balances
b)the practice of judicial review
c)the unwritten constitution
d)article i of the constitution

The correct answer is C. The two major political parties in the United States are considered part of the unwritten constitution.

Explanation:

The "Unwritten Constitution" is the series of legal, judicial and ethical precepts that, although not included in the Constitution, are part of the fundamental pillars that organize the government and guarantee the preeminence of the rule of law in the nation.

These are concepts that govern the country because they are fully accepted by society, which identifies positive results in them. In this sense, the existence of two predominant political parties (Democrats and Republicans) that agglutinate and monopolize the vast majority of the national political spectrum is socially accepted and considered positive, since it is considered to generate political and partisan stability, which may not exist in case of a multiplicity of political parties.

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.
