Answer:
The general, ultimate goal of extremist groups is to change society in a particular way. Extremist groups often hold strong ideological beliefs and seek to impose those beliefs on society through various means, which can include violence, propaganda, or political action. The ultimate goal is typically to create a society that reflects their ideology and values, which can be at odds with mainstream society. While violence can be a tactic used by extremist groups, it is often seen as a means to achieve the larger goal of societal change. The other options listed, such as growing by gaining new members or spreading terror to other parts of the world, may be strategies used by some extremist groups, but they are not the ultimate goal of extremism itself.
