You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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:`.

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.
Solution: Why has it been diminished?
Why? 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.

New input: CONTEXT: Under civil law frameworks based on common law (which we have in the US), there is the doctrine of res judicata -- or "already judged." Once the appeals process is complete, or the time frame for filing appeal has run out, res judicata states that the suit cannot be brought again, even for new evidence (there are exceptions, such as proof of fraud). Its purpose is to strike a balance between the rights of the defendants and plantiffs as well as to make the courts run more efficiently ... kind of like the principle of double jeopardy under criminal law. The U.S. military has affirmed it holds to the doctrine of res judicata. So in this episode, where the time for an appeal of the original case had likely long expired, it could not be brought again, as it would be dismissed as already ruled upon.  <sep>  Q: Does it seem to you that The Good wife season 4 episode 6 ending was wrong? A: where the time for an appeal of the original case had likely long expired, it could not be brought again, as it would be dismissed as already ruled upon  Q: Do you have legal knowledge to confirm that facts presented were mainly wrong? A: Under civil law frameworks based on common law (which we have in the US), there is the doctrine of res judicata -- or "already judged  Q: What are the grounds to reopen a military case? A: The U.S. military has affirmed it holds to the doctrine of res judicata  Q: Shouldn't the have Alicia, Kalinda or Will point that the case should be reopened? A: Once the appeals process is complete, or the time frame for filing appeal has run out, res judicata states that the suit cannot be brought again
