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:'.

[EX Q]: CONTEXT: I think it comes down to one point - can one mind actively dream two or more states simultaneously. For the dream within a dream thing to work .... the dreamer in level 1 (Yusuf) has to dream the Pasiv (sleep) machine into existence, in order to allow people to go down to the next level (the hotel dream of Arthur). For someone to simultaneously be maintaining level 1 and be able to go to 'sleep' and maintain level 2 seems unlikely - you'd essentially have to be 'awake' in each dream state. So it appears for the dream within a dream thing to work, you need as many people to dream as levels you wish to descend. This appears to be why Cobb wants Yusuf to 'go into the field', as he needs 3 dream levels (Yusuf, Arthur, Eames) - and he does not want to be a dreamer himself (for obvious reasons), and Ariadne was a late addition to the team. <sep> Q: Was it impossible to go into same person's dream each level down, or did it serve a purpose? A: I think it comes down to one point - can one mind actively dream two or more states simultaneously Q: Why did they have to choose a different person each time they went one level deeper in Inception? A: For the dream within a dream thing to work .... the dreamer in level 1 (Yusuf) has to dream the Pasiv (sleep) machine into existence Q: Couldn't they have kept going into Yusuf's dream all the way down? A: This appears to be why Cobb wants Yusuf to 'go into the field', as he needs 3 dream levels (Yusuf, Arthur, Eames <sep> FOLLOWUP_Q: How many dream levels are there?
[EX A]: Yes

[EX Q]: CONTEXT: The wiki states that the smaller portals were inter-dimensional "wounds" that would close/collapse quickly after forming, and that only the Demogorgon could make them because they took a lot of energy to create. Presumably the "demo dogs" are too weak to make portals like this, which is why they dig the tunnels instead. <sep> Q: Why is the portal so hard to close in Stranger Things 2, when the monster opened many in the first season? A: the smaller portals were inter-dimensional "wounds Q: So what makes them easier to close? A: would close/collapse quickly after forming Q: Who made these portals? A: only the Demogorgon could make them because they took a lot of energy to create Q: Is there anything else you can tell me about these portals? A: Presumably the "demo dogs" are too weak to make portals like this <sep> FOLLOWUP_Q: What do the demo dogs do in stranger things?
[EX A]: Yes

[EX Q]: CONTEXT: It's a nice scene just when the song Ecstasy of Gold starts. Actually the dog was not part of the original script. It was Leone's dog and it ran and escaped when the scene was shot. Elli's reaction is a natural instinct on being startled. Leone (perfectionist as he may be) liked the result so much that he decided to keep it <sep> Q: What is the meaning of the apearance of dogs in the good the bad the ugly? A: Actually the dog was not part of the original script <sep> FOLLOWUP_Q: Did the dog just walk on set and they kept the footage?
[EX A]:
Yes
