Detailed Instructions: 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.

See one example below:
Problem: 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?
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.

Problem: CONTEXT: It's hard to say because we really don't know what he's been doing exactly or why. He could be waiting for winter as he needs a way around/through the wall and waiting for the ocean near Eastwatch to freeze would allow him to walk around the wall. Or now that he "marked" Bran he is going to be able to break the magic barrier of the wall the same way he broke the barrier around the 3 eyed raven's cave. But a likely explanation is that him and his army simply move at the speed of plot. So he hasn't made it there because it's not time for that in the story and it's just a plot hole.  <sep>  Q: How is the night king not at the wall yet? A: It's hard to say because we really don't know what he's been doing exactly or why  Q: True. It takes a long time for any background information to really come to light. A: But a likely explanation is that him and his army simply move at the speed of plot. So he hasn't made it there because it's not time for that in the story and it's just a plot hole 
Solution:
Right. Are all white walkers from north of the wall?
