Step-by-step explanation:
In the development of public policy, political parties, interest groups, the media, and individuals all play important roles.
Political parties inform the public about topics and issues through their platforms and propose solutions.
Interest groups advocate for specific policy positions and work to influence policymakers.
The media serves as a gatekeeper, influencing public opinion and agenda-setting by determining which issues receive attention.
