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: 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 is here: Why has it been diminished?
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.

Now, solve this: CONTEXT: There is no published in or out of universe explanation about Guinan/her people and Q/the Q. It was never expanded on in the show, movies, in canon or non-canon books or video games, or any of the released production notes or interviews. Given how extensive the information we have about TNG and star trek in general, compared to other shows, that's very telling. Production must not want it to be known. It was a plot point that was abandoned and never brought up again in any shape or form. It almost makes it a discontinuity.  <sep>  Q: What was the prior relationship between Q and Guinan? A: There is no published in or out of universe explanation about Guinan/her people and Q/the Q 
Solution:
Did Guinan have any defensive powers against q's powers?
