<human>:  Who discovered the North and South pole?
<bot>: The North and South poles were discovered by the explorers who were sent to find them. The explorers were called explorers because they were exploring the world. They were sent to find the North and South poles because these locations were very far away from the rest of the world, and therefore it would take a very long time for someone to get there. The explorers found the poles and named them the North and South poles because they were in the north and south.
