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:`.

Positive Example 1 -
Input: 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?
Output: No

Positive Example 2 -
Input: CONTEXT: Spider-Man: Homecoming is following the Captain America: Civil War. I've seen the same trailer - and the clip with Spidey holding Cap's shield seems to be lifted straight from the CA:CW movie during the airport fight. Later in the trailer (or in another trailer), Peter is boasting to his friend about meeting Iron Man and the Avengers, and how he stole Captain America's shield from him.  <sep> FOLLOWUP_Q: When did Spider-Man steal Captain America's shield?
Output: Yes

Negative Example 1 -
Input: CONTEXT: Logan's plan earlier in the movie was to buy a sailboat and sail to the ocean with the Professor, where they would spend their last days. Out on the sea, the Professor wouldn't pose a threat to other humans when he lost his control over his ability. If I am not mistaken the Professor liked that idea - being out on the sea. When he died and Logan buried him, it was near a lake, so he was at least near water - Since Logan was emotional about the death of the Professor these were the only words he managed to say as a kind of eulogy. <sep> Q: What was Logan's plan? A: to buy a sailboat and sail to the ocean with the Professor <sep> FOLLOWUP_Q: Where did logan bury Professor?
Output: No

Negative Example 2 -
Input: CONTEXT: Yes. He's supposed to be the same character. The timeline of the story arc is all over the place now but Spectre could be regarded as a prequel to the series before Daniel Craig. Some say a reboot but apparently its all supposed to be the same story. This falls apart because of Judi Denchs M, Bond's previous encounters with Spectre and Blofeld etc though. <sep> Q: Is Franz Oberhauser related to the original Blofeld? A: He's supposed to be the same character <sep> FOLLOWUP_Q: Why was Bond running over the train?
Output: Yes

Now complete the following example -
Input: 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  Q: How many dream levels are there? A: he needs 3 dream levels  <sep> FOLLOWUP_Q: Is it possible to go further than 3?
Output: 


Answer: No
