instruction:
Given a paragraph about movies, and a set of conversational question answers about the paragraph, generate a relevant question to the topic of the paragraph. The paragraph has the prefix 'CONTEXT:'. Each conversation question has a prefix `Q:` followed by the answer prefix `A:`.
question:
CONTEXT: Leverage. Xavier's seizures cause everyone to be paralyzed. Logan's healing factor allows him some movement, but the closer he moves to Xavier the stronger the effect by Xavier is. By stabbing the walls, he uses them to climb towards an increasingly difficult to reach Xavier. It provides a hand hold he can push against, like rock climbing or climbing a rope.  <sep>  Q: Why does Logan stab walls? A: By stabbing the walls, he uses them to climb towards an increasingly difficult to reach Xavier 
answer:
Where was Xavier?


question:
CONTEXT: Keeping in mind what we now know (that the monster is The Man In Black), we can only speculate at what John actually saw. Each person who saw the smoke monster presumably saw more than just a large cloud of smoke - they saw some kind of vision in the monster (if memory serves, this is what happened with Mr. Eko for example). What John saw probably affected him in a way that he wanted to keep whatever vision he saw to himself.  <sep>  Q: Why didn't Locke say he saw the monster? A: What John saw probably affected him in a way that he wanted to keep whatever vision he saw to himself 
answer:
Why do you think John wanted to do this?


question:
CONTEXT: It is a common fact on TV that combat and injuries are stylized to make it look good rather than realistic. Have a look at pretty much any film fight where someone knows a martial art and compare that to someone who knows a martial art fighting for real. They are worlds apart. Even if you look at American Wrestling and BJJ you can see the difference. Knocking someone out with one punch is extremely difficult, especially if they are used to combat. I have taken an unpulled hit from a quarter staff on the top of my head which caused me to blackout later but I still didn't go down at the time. After almost 20 years of martial arts and living in rough areas I have only been knocked unconscious with one punch once, when I was 17 by the European Kickboxing champion. I was punched to the ground by a bouncer in Portsmouth when I was 20 but was still conscious until he stamped on my head. Most of the people in the Walking Dead would have starved or succumb to injuries by now if they were suffering this scenario for real. Not to mention being struck down by illness. It is just a convention of the media that people are routinely knocked out in one hit and recover completely when the plot demands it and don't when the plot demands that instead.  <sep>  Q: Are there a lot of head injuries in the Walking Dead? A: It is just a convention of the media that people are routinely knocked out in one hit and recover completely when the plot demands it and don't when the plot demands that instead 
answer:

Who is one of the characters that has a lot of head injuries?
