instruction:
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:`.
question:
CONTEXT: Finally found time to scan through the book. In it, Robert Highland is not an Inspector but rather a Sergeant. He is the #2 Scotland Yard officer working with the Sean Miller investigation after Commander Owens, although Owens thought he had a good mind for investigations and would make a fine Inspector some day. In the book version of events, Highland did not know about the schedule or route - they were picked by Commander Owens. Highland also did not have the conversation with Miller, and he survived the rescue despite being shot, remaining in critical condition with the bullet lodged near his spine. He then spent several months learning to walk again with a cane and leg braces. There is no indication in the book that Robert Highland was allied, or even sympathetic to, Kevin O'Donnell or his group of terrorists.  <sep>  Q: Was Inspector Highland the inside man? A: There is no indication in the book that Robert Highland was allied, or even sympathetic to, Kevin O'Donnell or his group of terrorists  <sep> FOLLOWUP_Q: When did the officers not seem to know what was going on?
answer:
No


question:
CONTEXT: It's hard to say because we really don't know what he's been doing exactly or why. He could be waiting for winter as he needs a way around/through the wall and waiting for the ocean near Eastwatch to freeze would allow him to walk around the wall. Or now that he "marked" Bran he is going to be able to break the magic barrier of the wall the same way he broke the barrier around the 3 eyed raven's cave. But a likely explanation is that him and his army simply move at the speed of plot. So he hasn't made it there because it's not time for that in the story and it's just a plot hole.  <sep>  Q: How is the night king not at the wall yet? A: It's hard to say because we really don't know what he's been doing exactly or why  <sep> FOLLOWUP_Q: True. It takes a long time for any background information to really come to light.
answer:
Yes


question:
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?
answer:

No
