How could the state have attempted to ensure that fracking continued?

It could have offered other cities tax breaks to allow the activity. A tax break is an item which avoids taxes. This includes tax exemptions, tax deductions and tax credits. In the United States, it is also used to refer to favorable tax treatment of a class of persons.

Hope this will do!

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.

i believe your answer is mountains.
