Step-by-step explanation:
The four factors that affect how diversity is changing society today are ethnicity, gender, politics, and education.
Ethnicity plays a significant role in shaping society as different ethnic groups bring diverse perspectives, cultures, and traditions. Gender also influences society by affecting power dynamics, opportunities, and social norms.
Politics can impact diversity by shaping policies, laws, and the inclusion or exclusion of certain groups. Education is another crucial factor as it can provide equal opportunities, promote understanding, and bridge gaps between different cultures and backgrounds.
