One of the functions of pressure groups is to articulate the opinion of their members.
Pressure groups are organizations that bring together individuals who share a common interest or concern and aim to influence government policy or decision-making. They provide a platform for their members to voice their opinions and concerns, and to advocate for change.
The goal of pressure groups is to represent the interests of their members and to influence the decisions and actions of those in positions of power, such as elected officials and government agencies. By articulating the opinions and concerns of their members, pressure groups can help shape public policy and bring attention to important issues.
