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 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:'.

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?
Solution: No
Why? The answer is not mentioned in the text. Hence not answerable.

New input: CONTEXT: He first sends the message of STAY. Remember the scene in the beginning of the movie just before Cooper visits the teachers of his children. We are shown that Murph has some thick lines on her book. In the end we are shown that she is actually figuring out the morse code behind the falling books represented by the thick lines. Thus she was indeed receiving the messages of STAY before getting the co-ordinates. Now in the teseract Cooper initially wants Murph to stay in the room, so he sends the message of STAY. When he realises that what has happened in the past cannot be changed, then he wants to save the future of mankind. That is why he sends the location of NASA to his past self. <sep> Q: If Cooper wanted to stay, why did he send the NASA Coordinates?
Solution:
Yes
