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: David was of great historical interest to the future A.I.s, since he had actual memories of human beings, who are apparently long extinct by their time. Beyond that, he was actually built by humans, where they are undoubtedly built by other A.I.s. Studying him would help them understand their own past. They wanted to preserve him, and although they are not organic, seem to have a morality which prevents them from simply taking him apart or locking him in a cage. <sep> Q: Why was David's happiness so important to the Mecha descendants? A: he had actual memories of human beings, who are apparently long extinct by their time <sep> FOLLOWUP_Q: What movie was this event in?
No

CONTEXT: Well, in answer to the first part: Yes, the water in which John Loomis (Chiwetel Ejiofor) was swimming/bathing when Ann Burden (Margot Robbie) came up to him is irradiated. Without getting too "spoilery", the area in which Ann lives seems to be one of very few (if not the only) radiation-free zones at the time of the story. However, the water in which John was swimming comes from outside of that area (the waterfall). As for the beneficial effects of the bath, I think the link to the "Silkwood Shower" reference by @Will-Feldman is probably as good an explanation as any. Try to get as much of the irradiated water off of the body as possible. John is obviously still going to be affected by his exposure, but there's no reason to allow more of the radiation to seep in if it can be prevented. <sep> Q: Why does Margot Robbie wash Chiwetel Ejiofor in Z for Zachariah? A: the water in which John was swimming comes from outside of that area (the waterfall Q: Is there radiation in the water? A: irradiated Q: What does irradiated mean? A: irradiated <sep> FOLLOWUP_Q: Does Margo have to wash anyone else?
Yes

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 <sep> FOLLOWUP_Q: Is it true that the queen kept dragons as prisoners?
No
