Given the task definition and input, reply with output. 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: Stupid? Not at all. The FBI tells Sonny Black that Donnie was an agent, to let them know that the FBI can infiltrate them at will. This will create suspicion for every new member going forward, and the whole idea is to break down the walls of trust so they'll rat on each other. It's actually a quite brilliant move on the FBI's part. <sep> Q: In the film Donnie Brasco, why did the FBI tell the mafia that Donnie was an undercover agent?
Yes
