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 don't have official source or script to draw from. However, my read on that scene is that they were waiting for the humans. The whole nest seems to be in a sort of button-up-and-fortify mode. The most the Vikings sniff of a dragon is the tail that gets whisked out of sight. This is more than likely intentional - note that the eerie sound that continues while the Vikings land and fortify continues right up until they punch the hole. It's a very similar sound to the sound the other Alpha dragons make in the second movie, while exerting dominance or control. The Alpha is holding it's nest on tight guard, possibly to pounce once it feels right. That all seems to go out the window when Stoick signals a fireball launched in. Whether that was just an agressive surprise, or read as some kind of direct challenge, I couldn't say for sure. The dragons in the tunnel though, didn't move until that moment, and it mostly seems to be an action of I'm-getting-the-heck-out-of-the-way as that Alpha decides to muscle out and deal with this personally.  <sep>  Q: Why didn't the dragons leave their lair earlier? A: The Alpha is holding it's nest on tight guard  Q: What is the Alpha and how is it different to the other dragons? A: exerting dominance or control  Q: How do the Alpha dragons exert dominance or control? A: The Alpha is holding it's nest on tight guard, possibly to pounce once it feels right  Q: What else can you tell me about the dragons or their lair? A: The dragons in the tunnel though, didn't move until that moment, and it mostly seems to be an action of I'm-getting-the-heck-out-of-the-way  <sep> FOLLOWUP_Q: I was wondering if the dragons lost their friends?
Output: 


Answer: Yes
