Teacher:Given a paragraph about movies, and a set of conversational question answers about the paragraph, answer a follow-up question from the paragraph. The paragraph has the prefix 'CONTEXT:'. Each conversation question has a prefix `Q:` followed by the answer prefix `A:`, and the follow-up question has a prefix `FOLLOWUP_Q:`.
Teacher: Now, understand the problem? Solve this instance: CONTEXT: Being choked unconscious can result in short term memory loss. It is likely that Harvey Dent may not remember Rachel asking or the question. Or the assault. Choking someone out doesn't knock them out for very long either. It is possible Batman drugged Dent inside the panic room and then took him home later and he woke up in his own bed.  <sep>  Q: Did Harvey Dent know that it was Bruce Wayne who locked him up? A: It is likely that Harvey Dent may not remember Rachel asking or the question  Q: Who did Harvey think locked him up? A: Rachel  <sep> FOLLOWUP_Q: Who actually locked Harvey up?
Student:
Batman drugged Dent
