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:'.

Let me give you an example: CONTEXT: The balance of power had shifted considerably since the first set of quotes. King Joffrey is dead, and his younger brother Tommen is now king. Unlike his wild card of an elder brother, Tommen is gentler and more prone to manipulation by his new bride. The Lannisters impeccable image has also been shattered. They failed to prevent the assassination of their king in the midst of his own wedding day, and the suspected assassin is the king's Lannister uncle. Not only do they look incompetent, they are divided among themselves. On the other hand, the Tyrells' situation is much stronger now. Tommen is already wrapped around Margaery's pretty little finger, and she knows that the assassination was orchestrated in part by her own family. In Margaery's eyes, the Lannisters look disoriented and lost. Putting on a show trial for one of their own, whom she knows is innocent of any wrongdoing. Whatever power Cersei held over Margaery has now been diminished. <sep> Q: What was Margaery's motivation to call Cersei 'sister' again? A: Whatever power Cersei held over Margaery has now been diminished.
The answer to this example can be: Why has it been diminished?
Here is why: The question is valid since it is on the same topic and a follow-up of the previous answer in the conversation. The question asks about the reason why the power held over Margaery by Cersei have diminished.

OK. solve this:
CONTEXT: I think that 90 seconds is just the amount of time it takes to take out the tracker. The reason they wanted to remove the tracker was to implant their own tracker into Lane. Lane, should he have gotten free, would've removed the tracker himself but now if he were to be freed he wouldn't know that he still had a tracker on him. This new tracker having been put in place by the IMF and not the Parisian authorities that were holding Lane and trying to get him back from Hunt's team making not only Lane but Walker not realizing that Lane was still being tracked. I also believe they did this in order to set Lane's tracker as visible again and when they set the drone away with Lane's tracker to keep the authorities on a goose chase thinking that Lane was still on the move while Hunt's team escaped with Lane. When they finally set the drone free you can hear helicopters passing by overhead. They drew the authorities closer to the tracker and then set it free instead of them trying to follow them to the sewers. <sep> Q: Why did Hunt's team set a 90 seconds limit to take out the tracker from Lane's neck? A: I think that 90 seconds is just the amount of time it takes to take out the tracker Q: Why did they want to remove the tracker? A: The reason they wanted to remove the tracker was to implant their own tracker into Lane
Answer:
How hard was it remove and implant the new one?
