Final answer:
The ritual of sending away a scapegoat to symbolize the removal of people's sins is known as the Day of Atonement or Yom Kippur in Jewish tradition.
Step-by-step explanation:
The ritual that included the sending away of a scapegoat as a symbol of the removal of the people's sins is known as the Day of Atonement or Yom Kippur. This ancient Jewish practice involves a scapegoat being symbolically burdened with the sins of the people and then sent into the wilderness, signifying the cleansing and forgiveness of the community's transgressions.
Unlike the ritual sacrifices of Mesoamerica or Greek traditions that usually involved offerings made at temples or altars, the scapegoat ritual was unique in its symbolic gesture of banishing sins away from the populace.
