Answer:
illegitimate Opportunity Structures
Step-by-step explanation:
Cloward and Ohlin emphasized that when individuals are blocked from pursuing success and wealth through a traditional and legitimate opportunity structure, they might tend to seek for wealth and success through non-traditional and illegitimate opportunity structures. These individuals tend to join gangs, become criminals etc. because the socially illegitimate groups could provide the means to gain access to material rewards and attain social status, that was originally not available to them.
