Final answer:
Ignoring the issue is the only option listed that cannot be used to lobby Congress to increase funding for Pell Grants. Proactive measures like writing letters, grassroots campaigns, and meeting with policymakers are effective methods for lobbying.
Step-by-step explanation:
The only option that could not be used to lobby Congress to change education policy and increase the amount of funding for Pell Grants is c. Ignoring the issue. Tactics such as writing letters to representatives (a), organizing a grassroots campaign (b), and meeting with policymakers (d) are all proactive approaches to influencing policy change.
Interest groups commonly engage in activities such as inside lobbying, outside lobbying, and promoting ballot initiatives to influence government policy. They also harness the power of organized group activities and civic engagement to increase their influence on governmental actions. Civically engaged individuals can write letters, join interest groups, and donate to political campaigns as individual-level ways to participate in the political process.
Conversely, ignoring the issue does not constitute a form of political participation in any way and would not assist in changing public policy or increasing funding for any cause, including Pell Grants.
