Answer 1

To narrow the scope of your research, the claim that would be most effective is: "The laws passed by the city government this year have had many support."

This claim specifically focuses on a particular timeframe ("this year") and a specific level of government ("city government"), which helps to concentrate the research on a defined set of legislation and public support.
