Given a paragraph about movies, and a set of conversational question answers about the paragraph, answer a follow-up question from the paragraph. 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: I believe that being raised as a wight requires active work on the part of the Walkers; I don't believe anyone killed by a wight will resurrect themselves automatically. Beyond that, I don't think we know all of the details about how that process works, what's required, etc. The only time, as far as I can remember, that we've seen it at work is the huge battle near the end of Season 5, where the Night King personally raised an army of dead wildlings as wights. It's also pretty clear that the characters in-universe don't understand it either. The Night's Watch is hyper-aware of the possibility of their dead coming back to life. They have burned the corpses of dead Night's Watchmen before. In fact, I believe in the Saason 6 trailer we've seen them trying to burn Jon's body as well, despite there being little chance of a Walker getting near it.  <sep>  Q: Requirements to join the Wights (The Army of the Dead) A: I believe that being raised as a wight requires active work on the part of the Walkers  Q: What is the process? A: Beyond that, I don't think we know all of the details about how that process works, what's required, etc  <sep> FOLLOWUP_Q: Do you have any examples?

[EX Q]: CONTEXT: In Prometheus, Elizabeth Shaw and Charlie Holloway are scientific partners who are also in a relationship before the events of the movie. They discover the location of LV-223 and get the support from Weyland to fund a scientific trip. It is entirely coincidental that they are in a relationship, though of course that fact is used later in the plot. They are a couple on the ship because they are responsible for the expedition. The situation in Alien Covenant is entirely different. This is a colonization ship, a deliberate, one-way trip to settle on another planet. It is clearly deliberate that the ship is (entirely?) crewed by couples who are likely to want to settle and raise families in their destination. I don't think you can extrapolate the second example to say it is 'encouraged officially'. Its clearly encouraged, possibly a requirement for the people funding a colonization of another planet, but why would it be a general requirement? The trip in Prometheus and the later Nostromo isn't one-way and is largely crewed by single people.  <sep>  Q: Is it a coincidence that there are many couples boarding ships in Alien? A: The situation in Alien Covenant is entirely different. This is a colonization ship, a deliberate, one-way trip to settle on another planet  <sep> FOLLOWUP_Q: I am wondering in the Alien universe, having a married couple to go onto the same trip is encouraged officially?
[EX A]: I don't think you can extrapolate the second example to say it is 'encouraged officially'. Its clearly encouraged

[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  <sep> FOLLOWUP_Q: Did Walter want Lydia to survive?
