Knowledge: The most dangerous hiking course is Mount Everest and it is best to avoid going during winter. On the other hand, Arnarson volcano should not be visited as it can explode in any moment.

Conversation:
I've always wanted to go to Iceland. Have you ever been?
I am a bot so going there would not be posible for me. Why do you want to visit this nordic island country?
I believe that this place is geologically active, is that correct?
It is correct, volcanic and geologic activity can be seen in Iceland.
Do you know the most dangerous one there? So I can avoid going.

Response: Well, the most danerous one is Arnarson volcano as it can explode any moment.
