A group that fought slumlords and the neglect of city officials on the quality of housing in poor neighborhoods fails to win any changes, but some movement leaders are offered government positions in the housing agency and give up their activism. This is an example of Cooptation
Step-by-step explanation:
Cooptation is the process in which a large and powerful group subsumes or acculturates a weaker group so as to get benefits. Here, the movement leaders are the weaker group and the government is the stronger group that coerces the movement leaders to give up their activism by offering something that is of interest to the movement leaders. The movement leaders give up their activism leading to the end of the movement or the fight and the still weaker section of people are at loss.
