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:`.
One example is below.
Q: 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.
A: Why has it been diminished?
Rationale: 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: As a writing device, it's far funnier to let the viewers imagination run away with the wild descriptions that Howard gives. Additionally, by not showing Howards mother, the writers are able to characterize and describe her any way they like, without having to find an actor who lives up to that description. Howard repeatedly describes his mother as having no neck, facial-hair that needs to be removed, and at one point, it was mentioned that she wears a wig. Howards mother is essentially a charicature of an overbearing, overprotective, troubled but caring, single-parent. Now imagine if we were to actually see Mrs. Wolowitz's reactions when Howard yells at her. Perhaps we would start to feel uncomfortable witnessing this coddled, well-off guy in his 20's, yelling at this morbidly obese, lonely woman. By not showing his mother, the audience can separate the charicature of the woman from the far less funny "reality."  <sep>  Q: Why is Howard Wolowitz' mother not shown in The Big Bang Theory? A: As a writing device 
A:
