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: Largely he gains his confidence from Tony Stark. Their working together and sharing their personal issues caused Banner to rethink the way he thought of "the other guy". Stark coped with his condition by turning it into the Iron Man, and helping others. Banner still feared what "the other guy" would do when unleashed. This was then reinforced after he is induced into becoming the Hulk on the Helicarrier. Upon awaking in the abandoned warehouse and learning the Hulk aimed for it to prevent casualties, Banner came to realize that the Hulk isn't always a danger to others. Thusly he chose to join the other heroes in New York City to defend Earth, whereas earlier in the film he had made it abundantly clear that his only role was to identify the location of the Tesseract. <sep> Q: Why does Banner finally allow the Hulk to come out? A: Banner came to realize that the Hulk isn't always a danger to others <sep> FOLLOWUP_Q: Where does he get the confident he needs to be sure he can point the beast towards the enemy, and not towards the Avengers?
Answer:
Yes
