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: I have not seen the movie so I have not seen the tools themselves. However operations which require cutting bone often require tools which might at first glance look like conventional power tools, such as drills. Tools designed for operations are designed to be very controllable in terms of speeds and the cutting implements themselves are made of high quality materials to prevent contamination, and can be autoclaved to be sterilized (using high pressure and temperature) but essentially they are not that far removed from hardware tools. In terms of being awake during surgery. The main reason to anaesthetise a patient in an operation is to prevent the pain and stop any movement which would disturb the operation. The scalp itself has pain receptors but the brain has none, once the work has progressed into the brain itself no pain from that part would be felt, but with a local topical anaesthetic the scalp might not be too painful. One could imagine that you could be awake but not be in much discomfort in a brain operation.  <sep>  Q: Is the brain sequence similar to reality or not? A: operations which require cutting bone often require tools which might at first glance look like conventional power tools, such as drills  Q: How can a person speak during his open brain surgery? A: The scalp itself has pain receptors but the brain has none, once the work has progressed into the brain itself no pain from that part would be felt  Q: How can they perform an operation where hardware tools are used rather than medical instruments? A: Tools designed for operations are designed to be very controllable in terms of speeds and the cutting implements themselves are made of high quality materials to prevent contamination 
answer:
But, is there any similarity between this operation sequence and reality?


question:
CONTEXT: It's a replaceable - some say rechargeable - power cell. You can see a spare on Ronon's belt in many shots, but there is as far as I can recall only one time you see him actually replace the power cell. In the tavern scene near the beginning of S2E7 "Instinct," he replaces the cell near the end of the conversation, just before he stands up. In S4E5 "Travelers" at about the 26 minute mark, you see Shepard ask Larrin if she has more "of these," referring to either the weapon, or the power cell he removes from the depleted gun. They are both weaponless because the gun is out of power. The show never actually shows how he replaces/recharges the cells, though. Probably for the same reason they never show the SG teams loading ammo into magazines. :)  <sep>  Q: Why doesn't Ronon's gun run out of power? A: It's a replaceable - some say rechargeable - power cell  Q: How does he recharge this power cell gun? A: You can see a spare on Ronon's belt in many shots, but there is as far as I can recall only one time you see him actually replace the power cell  Q: When does he do this exactly, I can't recall seeing him recharge it? A: In the tavern scene near the beginning of S2E7 "Instinct," he replaces the cell near the end of the conversation, just before he stands up 
answer:
Is this the only time he is seen recharging the gun?


question:
CONTEXT: It is not explained, but we can theorize. We don't know when he rented those books. He might have done so before buying his own (to ensure he indeed should buy them), or because the books weren't easy (or cheap) to purchase. Also remember that instead of renting books on a subject he is well versed in, he probably became well versed on the subject thanks to renting those books. Finally, despite those books in his apartment, IIRC we are never told what those books are about. They might have had nothing to do with the seven deadly sins (John Doe wanted to avoid having incriminating evidence on his home, perhaps?), and thus all of his knowledge came from renting the books in the library. The books in his house might have been educational on a ton of other subjects or philosophies. Also keep in mind, the Internet still wasn't a thing back then. And books such as the ones mentioned (on bondage, homicide, or by Italian Dominican friars) might have not been easily found in your regular old book store. Finally, you can also claim that he rented them to make the plot move along, as this was their main lead.  <sep>  Q: Why did John Doe need to check out books at a public library? A: It is not explained, but we can theorize 
answer:

What is your theory?
