Final answer:
People of color (POCs) become aware of racial groups based on their personal experiences and exposure to racial discrimination or prejudice.
Step-by-step explanation:
Racial groups have existed for a long time, but the realization of their existence varies for different people. People of color (POCs) become aware of racial groups based on their personal experiences and exposure to racial discrimination or prejudice. For example, historical events like the building of railroads by Asian people in the underground city of Pendleton, Oregon made students realize the harsh treatment faced by certain racial groups. Similarly, college students of color in a sociology class became aware of the academic disadvantages they faced when being grouped solely by their race.
