Step-by-step explanation:
Multiple Resource Theory (MRT) is a concept in social movement theory that explains movement success in terms of acquiring and mobilizing resources. According to McCarthy and Zald (1977), resources such as time and money are crucial for the power and effectiveness of organized movements. In this theory, social movement organizations (SMOs) with similar goals form a social movement industry (SMI), which represents the sum of all social movements in a society. The core idea behind MRT is that the greater the resources available and mobilized by a movement, the higher its chances of success.
