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: IMDb credits are generated by the filmmakers themselves (for smaller, independent productions) or representatives for the filmmakers/producers. On occasion crew and cast members get left off the submission form. I speak from experience as I appear as three different entities on IMDb because the filmmakers I worked for neglected to see if I was already represented and created a new page for me each time. This is certainly the case with other actors/crew members, and could go some way to explaining the discrepancies you have discovered. Bottom line is IMDb is not infallible, and it would indeed require some serious cross-checking with other sites in order to confirm the actor you are researching is the right one. <sep> Q: How to correctly identify an actor/actresses is in something that is not listed on their IMDB profile?
Solution:
Yes
