Which of the following is/are tactics used by interest groups to influence public opinion? Publicizing voting records of members of Congress Funding and publishing research Lobbying Advertising I don't know

Publicizing Voting Records and Publishing Research.

Explanation:

As they seek to influence the public opinion and not the government in this question, lobbying would be out as it is a tactic to influence congress members directly and not the public. Publishing voting records could be a valid tactic if said vote records were in favor of the group interest. Funding and publishing research is a valid tactic as well because it serves as a platform to get facts and data to the public, influencing its decision (in the scenario a research findings benefits the interest groups vision, obviously).
