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!

i want to say death; parole, probation, and fines are still being used all the time.
