Final answer:
Ideas for bills come from various sources including constituents, interest groups and lobbyists, specialized committees, and policy proposals from the executive branch.
Step-by-step explanation:
One of the three main sources of ideas for bills is from constituents who approach their legislators with issues in their community, such as the need for more school funding. Additionally, legislators may find inspiration for bills through their own initiatives or interests, as well as through recommendations from various interest groups and lobbyists, including those from corporations, labor unions, and advocacy organizations.
Moreover, ideas for legislation can also surface from the examination of issues within specialized committees, from policy diffusion from the federal government, or from laws that have been successful in other state legislatures. The executive branch of the government, such as the president or prime minister, often submits policy proposals to the legislature for consideration as well.
