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: The problem wasn't so much that she resurrected him, as how she did it. She controlled time itself and wrapped it around him, giving him life with a power that she didn't understand. Imagine it as someone who has a prosthetic limb and needs to learn to control it. She tried to place something (his life) gently back into time and instead punched out violently. Time around him solidified as if it were that paste that goes solid with kinetic energy. She made it so that his death was something that just couldn't happen, wrapping him in time energy that jumpstarts his system whenever he dies, almost like an antivirus seeking out a problem with a program and fixing it. Of course, over time that energy would wear down and eventually dissipate, in this case by his own choice which allowed him to finally die. Exposure to time travellers would likely drain some of the energy too, as would the vortex he guarded in Torchwood. It never got explained but I like to think that the whole Face of Boe thing came about due to cellular mutations introduced in his system over the course of millions of reconstitutions over the years. Having the effect turn off (like it did in Miracle Day, for example) every so often would allow him to be mutated from radiation enough that over centuries he could become as he was when he died. That's my personal view on things.  <sep>  Q: How did Rose make Jack immortal? A: She made it so that his death was something that just couldn't happen  Q: How did she revive Jack? A: She controlled time itself and wrapped it around him, giving him life with a power that she didn't understand  Q: How did Rose use the Time Vortex power? A: wrapping him in time energy that jumpstarts his system whenever he dies, almost like an antivirus seeking out a problem with a program and fixing it  <sep> FOLLOWUP_Q: How often does he die and need this done?
[EX A]: Yes

[EX Q]: CONTEXT: I think he was talking about his dead wife: Parry is saying he remembers everything about what happened and forgives Jack, so Jack can find peace, that's why he was crying (Jack is the wounded, tormented Fisher King and Parry the simple-minded man that helps him, in my interpretation of the movie).  <sep>  Q: Which girl Parry was referring to after waking up?
[EX A]: Yes

[EX Q]: CONTEXT: Travellers is about saving people in the future not in the present by altering the course of history. The people from the future can only do this safely and without unpredictable side-effects on the timeline if they don't "save" lives in the past. Their future technology actually does allow them to replace people who were not about to die, but they regard this as a moral problem and it is forbidden. But they can take over those lives if they were about to be eliminated from the timeline, hence the apparent paradox of "saving" McClaren. But they haven't actually saved McClaren at all, they have replaced him with a traveller. Early in the series only people about to die get replaced. Obviously the whole point is to alter the timeline but the travellers are aiming not for minor alterations like saving a single, random life, but for big alterations that radically change the course of history. One of their protocols actually forbids them from saving other lives as well even when they know someone is about to die (but not be replaced). This [minor spoiler alert] becomes a source of some dramatic tension in later episodes.  <sep>  Q: Why does MacLaren die in the first episode of Travelers? A: Travellers is about saving people in the future not in the present by altering the course of history  <sep> FOLLOWUP_Q: what does this mean, How can people do this?
[EX A]:
Yes
