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: Ricin is extremely toxic. It has an LD50 (the lethal dose for 50% of people exposed) of 30–40mg per kilogram when ingested (its much much more dangerous when introduced to the body in other ways). Guessing Lydia's weight at around 50kg (110 lbs) would lead one to think the LD50 would be no more than 2g of ricin. It has a military-developed antidote, which has had only limited trials in humans. Ricin is a chemical subject to the Chemical Weapons Convention, in the same schedule as nerve agents Sarin and VX. (All this information gleaned from Wikipedia) Walt also only told her when she'd already begun to experience symptoms, so less likely to recover even if treated. Even if she sought attention and gave them this information it seems unlikely that she would recover. Even if she's not been given a lethal dose, survivors of ricin often suffer from long term organ damage, so she would have a pretty miserable and presumably shortened life even if she does survive. I think Walt probably weighed her slim improved chances of survival, against the pleasure of knowing that she was aware who had done this to her. I considered an answer like @Keen's too — perhaps she would not go to a hospital in fear of the attention, but I think this is less likely, even the risk averse would put fear of death above prison.  <sep>  Q: What is ricin? A: Ricin is a chemical subject to the Chemical Weapons Convention, in the same schedule as nerve agents Sarin and VX  Q: Could Lydia get medical help and survive a ricin poisoning? A: Even if she sought attention and gave them this information it seems unlikely that she would recover  Q: Did Walter want Lydia to survive? A: I think Walt probably weighed her slim improved chances of survival, against the pleasure of knowing that she was aware who had done this to her  Q: Why did Walter tell Lydia what he did to her? A: I think Walt probably weighed her slim improved chances of survival, against the pleasure of knowing that she was aware who had done this to her  <sep> FOLLOWUP_Q: Why did Walt poison Lydia with ricin?
[EX A]: No

[EX Q]: CONTEXT: The short answer, which is probably the best answer, is that he was an experienced hunter and wanted to hunt "the most dangerous game"; a combat soldier. You'll note that he never kills unarmed humans (which is why Anna got sent to the chopper unarmed), and at the conclusion he decided to engage in hand-to-hand combat against Dutch, whom he deemed to be a worthy opponent.  <sep>  Q: Why did the first Predator come to Earth? A: The short answer, which is probably the best answer, is that he was an experienced hunter and wanted to hunt "the most dangerous game"; a combat soldier  Q: Was he already an established hunter? A: he was an experienced hunter  Q: Was he just hunting for more trophies? A: wanted to hunt "the most dangerous game"; a combat soldier. You'll note that he never kills unarmed humans  <sep> FOLLOWUP_Q: I see. So he would only attack armed humans. Got it
[EX A]: Yes

[EX Q]: CONTEXT: That is just a simple plot twist, or character development. The Harry Potter series is a pretty straight forward tale of good vs evil, and does not deviate much from that. A twist ending would be Harry becoming a worse villain than Voldy, or Voldy winning and everybody dying. Or that it was all a dream of Harry, who's still living under the crawlspace.  <sep>  Q: Is a twist ending that occurs at the end of a series of films still called a twist ending? A: A twist ending would be Harry becoming a worse villain than Voldy, or Voldy winning and everybody dying  Q: Are you talking about Harry Potter? A: That is just a simple plot twist, or character development  Q: Is Harry a good guy or bad guy in the story? A: The Harry Potter series is a pretty straight forward tale of good vs evil, and does not deviate much from that  <sep> FOLLOWUP_Q: Can you tell me anything else about the movie, it sounds interesting?
[EX A]:
