Task: Question Answering
Input (English): Context: They have literally TONS of castles all over the place . I had to have seen at least 10 just driving around . Coupled with the fact that tourism is very very small in Wales they do n't have visitor centers and charge you to see them . You just drive up and walk in . 
Question: Why do they have so much of what they have ?
Output (English): The castles must 've all been built in the past .
