What did christopher's trip to london do for his self confidence? has to do with the book 'the curious incident of the dog in the nighttime'.

First off, The Curious Incident of the Dog in the Nighttime was an amazing book, just saying. 
Second, I'll give the answer a go!
Christopher's trip to London helped make him feel more independent and to show him that he could do things on his own. He was able to go all on his own with no help (except from his rat, Toby, of course). And so, this trip showed him that he was even smarter than he thought he was.
This is not the full answer. If you need more, maybe go back over the book a little bit!
I hope this helps out!

I'm not going to write 150 words lol, but i will you with giving you examples of how they kept the animal population from revolting. napoleon made a list of rules, and told everyone how "important they are even though he was known to break them and then have them changed by the only animal who could read on the farm. none of the animals were intelligent enough to read, so they never knew if they had been changed or not which was an advantage to napoleon. napoleon constantly reminded them that if they revolted they would have to go back to mr. jones' way of things, which in retrospect was "worse" (wasn't really worse though, he was just saying that to intimidate since he didn't wanna lose his power). one of the main reasons they revolted in the first place was food, and of course if they revolt napoleon will not share food with them.
