TASK 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:`.
PROBLEM: 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?

SOLUTION: No

PROBLEM: CONTEXT: No. The 1994 version was based off of Norse mythology, as the wearer of the mask became a reincarnation of Loki (yes, the same Loki from Thor/The Avengers fame, and a bonafide prankster) whereas the 1961 Mask was a psychological thriller/horror movie where the wearer of the mask was slowly driven insane. There is a fine line between becoming a prankster and committing murder, but the line exists, nonetheless. However, in a larger context, the 1994 movie was based on the Dark Horse comic of the same name, which shared a closer storyline with the 1961 movie. The 1994 version was also intended to be a horror series, but the story was changed along the way. So, in some cases they are, in fact, related.  <sep>  Q: Was the The Mask 1994 (and subsequent cartoon) inspired by The Mask 1961 A: No. The 1994 version was based off of Norse mythology  Q: Norse mythology, how did this shape the film?

A: The 1994 version was also intended to be a horror series, but the story was changed along the way. So, in some cases they are, in fact, related  Q: What was changed about the story? A: the wearer of the mask was slowly driven insane. There is a fine line between becoming a prankster and committing murder, but the line exists, nonetheless  <sep> FOLLOWUP_Q: Can you tell me anything else about the Mask that might find interesting?

SOLUTION: No

PROBLEM: CONTEXT: Yes, multiple dogs can talk. Another one that has in multiple episodes is Brian's gay cousin Jasper in L.A., whom has a full time job and even gay married a human.
