Given a paragraph about movies and a set of conversational questions and answers about the paragraph, say whether the passage contains sufficient information to answer the follow-up question. Say Yes if it is answerable; otherwise, say No. The paragraph has the prefix 'CONTEXT:'. Each conversation question has a prefix 'Q:' followed by the answer prefix 'A:', and the follow-up question has a prefix 'FOLLOWUP_Q:'.

Let me give you an example: CONTEXT: I think it's deliberately ambiguous. If it's real, the inconsistencies are easily explained by Vidal's fascist belief system. These elements simply are not part of his world. If it's fantasy, then of course only Ofelia can see these thing because she imagined them. I think part of Del Toro's purpose in the film was to maintain the plausibility of both of these interpretations. <sep> Q: Is Ofelia just dreaming things to get herself in a fairy world? A: If it's fantasy, then of course only Ofelia can see these thing because she imagined them Q: Are the things happening for real but visible only to Ofelia? A: If it's real, the inconsistencies are easily explained by Vidal's fascist belief system. These elements simply are not part of his world <sep> FOLLOWUP_Q: When Vidal pulls the mandrake root out of Ofelia's mother's bed, is it just a normal root?
The answer to this example can be: No
Here is why: The answer is not mentioned in the text. Hence not answerable.

OK. solve this:
CONTEXT: In the books it is yet to be discovered if he is brought back to life for what greater purpose. But one thing is for sure, it isn't just one thing he did, but many. Probably in the books he is the one who kills the Night King, because it was clear from David Benioff's interview that they wanted to subvert expectations, they wanted someone who was not Jon to kill the Night King. So I think in the books he came back to life for also killing the NK. He was brought back to do a lot of things if you start to see it that way, a chain of events that led to a lot of things. Defeated Ramsay, showed the World that the dead are coming, prepared for the Long Night and battle of Winterfell. Successfully defeating NK would not have been possible without him. What the Lord of Light could have wanted? Well, we don't even know what LoL was, didn't know what his intentions were, who were his enemy but one thing we know for sure, all victories inevitably came at a cost. To bring a new World, Jon Snow had to stab his love in the belly. So there we have the Azor Ahai theory jumping in, not totally similar but was a good deal. <sep> Q: What was the purpose of bringing back Jon? A: He was brought back to do a lot of things if you start to see it that way, a chain of events that led to a lot of things <sep> FOLLOWUP_Q: What are some of the reasons?
Answer:
Yes
