Explanation
The matching is based on understanding the nature of each concept. Affirmative action involves differential or special treatment for specific groups to promote equality, hence it matches with banks offering higher interest rates to senior citizens. Equality of opportunity means ensuring that everyone gets a fair chance to develop their capabilities, which is reflected in every child getting free education. Equal Rights refers to identical treatment and same legal entitlements for all citizens, exemplified by every adult citizen having the right to vote regardless of any distinction.
