Given a paragraph about movies, and a set of conversational question answers about the paragraph, generate a relevant question to the topic of the paragraph. The paragraph has the prefix 'CONTEXT:'. Each conversation question has a prefix `Q:` followed by the answer prefix `A:`.

Example input: CONTEXT: The balance of power had shifted considerably since the first set of quotes. King Joffrey is dead, and his younger brother Tommen is now king. Unlike his wild card of an elder brother, Tommen is gentler and more prone to manipulation by his new bride. The Lannisters impeccable image has also been shattered. They failed to prevent the assassination of their king in the midst of his own wedding day, and the suspected assassin is the king's Lannister uncle. Not only do they look incompetent, they are divided among themselves. On the other hand, the Tyrells' situation is much stronger now. Tommen is already wrapped around Margaery's pretty little finger, and she knows that the assassination was orchestrated in part by her own family. In Margaery's eyes, the Lannisters look disoriented and lost. Putting on a show trial for one of their own, whom she knows is innocent of any wrongdoing. Whatever power Cersei held over Margaery has now been diminished. <sep>  Q: What was Margaery's motivation to call Cersei 'sister' again? A: Whatever power Cersei held over Margaery has now been diminished.
Example output: Why has it been diminished?
Example explanation: The question is valid since it is on the same topic and a follow-up of the previous answer in the conversation. The question asks about the reason why the power held over Margaery by Cersei have diminished.
Q: CONTEXT: For the same reason that Jeff doesn't immediately call the police with his suspicions: fear that if Thorwald realizes he has been made by an outside observer, he will dispose of all the evidence and escape without prosecution... Lisa is buying more time by being taken under arrest, and the event was intended to appease Thorwald to some extent. He was already making mistakes (retaining his wife's wedding ring due to sentimentality), and Lisa was clinging onto the thought that their plan was not yet foiled. The arrest itself was actually a means of getting Lisa safely out of the apartment, and of getting the wedding ring (as evidence) into the hands of the police.  <sep>  Q: Why didn't Lisa tell the truth about Thorwald to the police? A: fear that if Thorwald realizes he has been made by an outside observer, he will dispose of all the evidence and escape without prosecution 
A:
Why did she get herself arrested?
