This question is incomplete, here´s the complete question.
A group of migrant farm workers only employs one lobbyist, so it isn't able to convince many legislators to support its agenda.
What possible disadvantage of interest groups does this scenario illustrate?
A. They serve as watchdogs over government activity.
B. They inspire people to participate in politics.
C. They sometimes resort to unethical tactics.
D. They lack power unless they are well funded.
Answer: D. They lack power unless they are well funded.
Explanation:
Interest groups need a lot of money to be able to lobby because maintaining an office in Washington, D.C, in addition to them paying for meals, trips, and other operational expenses of the lobbyist, can be extremely expensive.
While money alone doesn´t guarantee that the interest group will have a stronger influence, the lack of money might be completely crippling.
