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: The Transformers aren't very well explored in the Michael Bay movies, so we'll have to judge according to the other (better explored) continuities. While the process of switching alternate modes in the movie seemed effortless, it might not have been. In other continuities the switch is either energy consuming or a major physical operation. So just changing to another vehicle might be a very expensive step that one does not take lightly. Also, the alt-mode seems to be a very personal aspect for each Transformer, which serve a similar function as clothes do to humans. They are a reflection of the owner, and once it is chosen it tends to stay the same. Transformers have been known to keep the same alt mode for thousands of years, which isn't really that long when you remember that their life span can stretch into the millions of years. <sep> Q: Why do the Transformers always transform into the same cars? A: just changing to another vehicle might be a very expensive step that one does not take lightly Q: Why is changing into another vehicle so difficult? A: the alt-mode seems to be a very personal aspect for each Transformer, which serve a similar function as clothes do to humans Q: What is the alt-mode and why is it significant? A: a very personal aspect for each Transformer, which serve a similar function as clothes do to humans. They are a reflection of the owner Q: How do the vehicles reflect the personality of the transformers? A: a similar function as clothes do to humans Q: What else can you tell me about the transformers? A: Transformers have been known to keep the same alt mode for thousands of years <sep> FOLLOWUP_Q: What makes a transformer change their alt-mode?
Answer:
No
