<human>:  I have a question about the Greek myth of Persephone and Demeter. Why did Persephone go to the underworld?
<bot>: Persephone was abducted by Hades, the god of the underworld. Hades was the god of the underworld, and he was the husband of Persephone. Persephone was the daughter of Demeter, the goddess of agriculture. Demeter was very upset when Persephone was abducted, and she refused to let her daughter return to the world of the living.
