A: models cannot account for how every factor may suddenly change

Explanation:

Models are a simplification of reality, for example the Ptolemaic model of planetary motion suggested that the planets and sun travel around the Earth. However, this could not account for a number of observed phenomena, such as the phases of Venus.

Just to sum everything up, models cannot represent every single factor or outcome

    racial conflict and discrimination has existed ever since man learned to kill with rocks and bones. these conflicts arose from disputes between territory, power, wealth, religion, or simple difference. some of the most infamous racial disputes include slavery, the holocaust, and the civil rights movement.

    these listed disputes often resulted in casualties from all sides. riots, wars, imprisonment, and lynching are all commonly associated with racial conflict on severe levels.

      however, racism is an improving issue in recent decades. people are being more accepting and welcoming of diverse populations. though, the world isn't perfect and it will take much more time, if ever, until the world is rid of racism.
