Kurt Lewin believed that to create long-lasting social change,an action plan needs to

A) involve the cooperation of the people from the setting of interest
B) be based on a broadly defined social problem
C) receive consistent government funding
D) be based on the interest of the stakeholders only

Kurt Lewin believed that involving the cooperation of the people from the setting of interest is essential to create long-lasting social change. This approach is called the participatory approach, which emphasizes the involvement of stakeholders, including those affected by the social problem, in the creation of the action plan. This helps to ensure that the plan is practical, relevant, and effective in achieving its intended goals. Thus, choice A is the best answer. Choices B, C, and D are not supported by Lewin's ideas. While a broadly defined social problem may be important for identifying the scope of the issue, it is not sufficient to create a long-lasting social change. Consistent government funding may be helpful, but it is not necessary for creating social change. Lastly, an action plan based on stakeholders' interests only may not be effective in achieving the broader goals of social change.
