Answer:
True
Explanation:
Advocacy is similar to activism in the sense that it is an activity that has the goal of influencing broad decisions that affect social, economic, or legal matters.
Lobbying is a more specific activity in which private groups or individuals try to influence legislators or regulators decisions about specific issues that may affect their interests.
For example, a corporation can be an advocate of lower taxes in general, and fund a think tank that does economic research that supports lower taxes. The same corporation can have lobbysts in Congress trying to influence member of Congress to lower specific tax rates during the discussion of a tax reform.
