Step-by-step explanation:
The concept of 'race' is socially constructed, meaning that it is defined by society rather than being based on scientific or biological factors.
Historically, race has been categorized based on physical traits like skin color, but these categories have changed over time and vary across cultures.
The labels for racial groups have often connoted regions or skin tones. While there are genetic markers for certain physical characteristics, such as skin color, race is not scientifically valid as a way to categorize people. Instead, race is a social construct that has been used to justify discrimination and inequality.
