Step-by-step explanation:
The three basic types of gangs, based on their primary activities and values, are economically-driven gangs, reputation-oriented gangs, and politically-motivated gangs. An economically-driven gang is primarily involved in criminal activities aimed at financial gain, such as drug trafficking and theft. Reputation-oriented gangs seek social status and dominance within a particular area through fear and intimidation. Lastly, politically-motivated gangs are those that have origins or ties with political organizations and may engage in activities that are designed to influence political power or provide financial support to certain political parties.
