Answer:
The youngest girl in the clan was sacrificed to insure a good crop.
Explanation:
The New Yam Festival (The Feast of the New Yam) is a celebration showing how important yam is in the social-cultural life of Igbo people. It symbolizes the conclusion of a harvest and the beginning of the next work cycle. It's held every year at the end of the rainy season in early August.
The evening before the day of the festival, all old yams of the previous year are consumed or discarded. As the festival is an occasion for giving thanks to Ani, the Earth goddess, who is considered to be the source of fertility, the arbiter of morality, and in close contact with dead ancestors of the clan, new yams are offered to her. All cooking and serving utensils are washed.
The only thing that doesn't take place during this festival is the sacrifice of the youngest girl in the clan.
