Definition: 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:`.
Input: CONTEXT: The implication is that the inmates are potentially violent and presumably the biggest danger from unarmed but psychotic patients is biting/scratching/gouging at the face and eyes. Clearly the protection is deliberately crude and underlines the primitive and brutal conditions in that setting in a way that more refined protection might not. You could also speculate that the head cages reflect the appearance of the barred cells and by placing them on the guard's heads it is a metaphor for the idea that the inmates are prisoners of their own madness. Equally by obscuring the guards faces with a crude and claustrophobic cage they are somewhat dehumanised and more like automata than medical staff. Indeed the whole visual style of the film uses a lot of elements which evoke stylized dreamlike of hallucinogenic states which confuse individual sense of identity and many of the characters are driven by some sort of obsession and it is implied that Dr Seward is as much a prisoner of his work as the peopel he treats (or at least studies).  <sep>  Q: Why are the asylum guards wearing cages on their heads?

Yes
