Timelines are tools that help historians represent and understand the past. On a timeline, you can see major events, when they happened and how they relate to one another.
Timelines are visual aids. They list major events in chronological order. They help us see
cause and effect, and they can show how groups and events overlap in time, too. For
example, a timeline of ancient Mexico might show the dates when different civilizations
flourished. You might see on that timeline that the Olmec and Zapotecs were in different
parts of the country during the same period of time.
Which of these questions could you most likely use a timeline of ancient Mexico to
answer?
А
What colors are on the Mexican flag?
B) What languages are spoken in Mexico?
When did the Olmec civilization flourish?
What did the ancient Zapotecs typically eat?

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.
