Final answer:
Competitors are willing to cooperate and form lobbying associations to represent the interests of their industry more effectively.
Step-by-step explanation:
Business groups are indeed influential because their lobbying and other efforts are well-coordinated. This is true because when competitors come together to form lobbying associations, they can pool their resources, expertise, and influence to effectively advocate for the interests of their industry. For example, trade associations and professional organizations represent the interests of particular industries and professions, and they employ specialists to advocate for their clients among lawmakers. By working together, business groups can amplify their voices and achieve their desired outcomes.
